  1. its a chronography dial, probably can~~~~i think its very cool!!!!!!!!!!!!!!limited to 100 pieces, the price of the "Leica Watch" would definitely be not lower than the Leica Camera :)
  2. There are many shapes of the crystal, the most common shape is tabulate shape, there are also arch shaped crystal and domed crystal. Generally speaking, the shape of crystal need to pair the pattern of the case firstly, because as the appearance of the watch, the case and the crystal need to be integrated. So if the case is arch shaped, the crystal should be arch shaped as well. The arc shape crystal is generally paired to the fashion watches, even some watch case curvature is exaggerated. But there many arc crystal in normal watches, such as Omega. And there is another advantage of the arc shape crystal, which is it can change the lump reflection into point reflection or line reflection to reduce the reflect light, especially when the crystal is plated(the effect is even better when the inside surface and outside surface are all plated), the increase of the crystal transmittance makes the reflect light reduced to minimum. All the waterproof watch are complimented with a thick crystal(generally 3-4mm). This kind crystal will be made into domed shape because this structure has greater compressive strength. The crystal of the professional diving watch for the special purposes are all domed shape like half a sphere besides the thick watch case. The shock resistance of arc shape crystal feels better than that of the tabulate shape crystal, especially the sapphire crystal, but not unzerbrechlich, don't throw it to the ground. I have a RADO "Black Pearl", and the domed sapphire crystal was broken. To replace a domed shape crystal is very expensive, and the craft of this shape crystal is very complicated, which is made of very thick raw material and slowly griding it to mold eventually. The arc shape crystal is kinda like the presbyopic glass block, which is actually a concave-convex len. I've tested a crystal with a lensometer, and the result shows that the crystal has +845 spherical equivalent while the +400 spherical equivalent is equal to zoom double, that means this crystal is equivalent to a 2 times magnifying glass. This kind crystal is good for the people with weak eyes and watches with calendar, because it has amplification effect. But if the crystal is too close to the dial, and the dial will out of focus, only when the focal length is completely aligned the amplification effect is the best. And the larger curvature, the better amplification effect.
  3. Heritage Navigator 160th Anniversary Tissot celebrates its 160th Anniversary with a piece first created for Tissot’s centenary in 1953, which reflects its love for new horizons. The Tissot Heritage Navigator is the ultimate traveller’s watch. It portrays that vintage class as well as providing the modern business man’s tool. This timepiece will allow you to be right on time, no matter what your location around the globe may be, with its automatic chronometer precision, officially certified by COSC (Contrôle official Suisse des Chronomètres) and its multiple time zones. You will even be able to take into consideration the time differences when organising those important conference calls with people from different parts of the world. Once you have chosen and set the watch to the country of your choice, that time zone will be indicated by the numbers on the bezel. In order to find out the time of any of the other of the 23 countries, simply take a look at the time indicated by the minute track on the dial in front of its Capital. This watch is the perfect illustration of what the company stands for with its essence of tradition and that touch of innovation. Tissot has always aimed to provide its consumers with indispensable tools of precision, and after 160 years, this watch shows that it is still the case today. Technical Specifications Swiss made Automatic chronometer movement officially certified COSC 316L stainless steel case with engraved see-through case back Domed scratch-resistant sapphire crystal with antireflective coating Water resistance up to a pressure of 3 bar (30 m / 100 ft) Leather strap with folding clasp with push-buttons Numbered edition
  4. I just acquired this watch around one week ago and I thought I would do a review as I like to read reviews before buying a watch and for people that would like to buy it for fun or before spending more money on a real pilot watch. I bought the watch on Ebay. Price is around 120$ US for the By it now ads. I think it's against the rules to name the vendor so, you can PM me in the worst case. Case: The case is a little bit smaller then what it's suppose to be. I measured it to around 46mm. The version I got is the PVD one. The finish is correct, because it's a sandblasted case the finish is really smooth but the PVD finish is not applied evenly everywhere, I could see a small difference inside the lug. Lug-to-lug is around 56mm. Strap size is 22mm which is common so it's a good thing for strap changes. Around 16mm thick with the domed mineral crystal. Unfortunately there is no coating on it as you can see reflexion on some of the pictures. As you can see, the case base is brushed stainless steel. Would have been nice to be PVD too but it's would be more expensive and when we were it we don't see it. It got a new version of crown, it's still an ''onion'' one but with a lot less mark on it. Movement: Inside is a Seagull 2542 according to what I could find on the net. As of now everything is smooth, could be smoother as it's only around 21 000 BHP. So far after one week it lost around 20sec. Dial: I took the black dial with white marking. There is other version or it also. It's inspiration is coming from aviation as you can see. The is the logo at 3h but other then that the dial is simple. As far as we are concerned with lume, well it's below average as you can see in the picture, but better then the other parnis I had in the past. Strap: I choose the brown version of the strap as I already got black one so the vendor switched them. The watch is a bit stiff at first but seems to soften after one week so should be better after a period of time. It's 22mm wide and 4mm thick. It got raw finish on the side. The buckle is a PVD one, which take it's inspiration from PAM. A good thing is that it's a screw in buckle. Normally it's spring bar so it was a nice surprise. Conclusion: For the price it's a great watch. I always wanted a pilot watch but did not wanted to pay a lot.
  5. Oyster Perpetual Milgauss Rolex is presenting a new version of the Oyster Perpetual Milgauss with unique and symbolic aesthetics. Its green sapphire crystal marked a first in watchmaking when it was introduced on the Milgauss in 2007. Now this crystal is combined with an electric blue dial, an allusion to the emblematic lightning-boltshaped seconds hand and the watch’s technical purpose as a paramagnetic timepiece designed for engineers and scientists in the 1950s, a golden age of scientific research. Seen through the green sapphire crystal, the Z blue dial – a name derived from its zirconium content – takes on a powerfully attractive magnetic hue. AN AVANT-GARDE WATCH Ever since its launch, the Milgauss has remained an avant-garde watch. It was created in 1956 for engineers and technicians who are exposed in their work to magnetic fields which disrupt the performance of mechanical watches. It was designed to resist strong interference of up to 1,000 gauss, hence its name – “mille” being French for thousand – while maintaining its performance and precision as an officially certified chronometer. A pioneer in magnetic resistance, it became known as the watch worn by scientists at the European Organization for Nuclear Research (CERN) in Geneva and gained a reputation as the ultimate watch of science and technological progress. Several innovations contribute to its resistance to magnetism. The first line of defence is a shield made of ferromagnetic alloys that surrounds the movement within the Oyster case, an invention patented by Rolex in 1954. The second line of defence involves two of the movement’s key components, the oscillator and the escapement, which are made of innovative paramagnetic materials developed by Rolex since the 2000s. THE OYSTER CASE, SYMBOL OF WATERPROOFNESS AND ROBUSTNESS The 40 mm Oyster case of the Milgauss, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness and reliability. The characteristically shaped middle case is crafted from a solid block of particularly corrosion-resistant 904L steel. The fluted case back is hermetically screwed down with a special tool exclusive to Rolex watchmakers. The winding crown, fitted with the patented Twinlock double waterproofness system, screws down securely against the case. The crystal is made of virtually scratchproof green sapphire. The waterproof Oyster case provides optimal protection for the Milgauss’s highprecision movement. CALIBRE 3131, SUPERLATIVE PARAMAGNETIC CHRONOMETER The Milgauss is equipped with calibre 3131, a self-winding mechanical movement entirely developed and manufactured by Rolex. Like all Rolex Perpetual movements, the 3131 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. It includes Rolex-patented components to guarantee the level of resistance to magnetic interference for which it is named. The escapement of the Milgauss features a paramagnetic escape wheel made of a nickel-phosphorus alloy. This component is produced using a micromanufacturing technology (UV-LiGA) that is entirely mastered in-house. The oscillator, the true heart of the watch, has a blue Parachrom hairspring patented and manufactured by Rolex in an exclusive alloy of niobium and zirconium. Insensitive to magnetic fields, the Parachrom hairspring offers great stability when exposed to temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks. THE OYSTER BRACELET, COMFORTABLE AND SECURE The Oyster bracelet of the Oyster Perpetual Milgauss is very secure and comfortable to wear. It is equipped with a folding Oysterclasp, designed by Rolex. It also features the ingenious Rolex-patented Easylink rapid extension system that allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.

  6. The GDF-100 is one of Casio's newest models only being announced officially mid-March. Unlike many of the mid-high end G-Shocks the GDF-100 is readily available from both the high street and online retailers. So, onto the watch itself, the model reviewed is the GDF-100-1AER. First impressions are good. The watch comes well packed as expected with a card outer and a metal 'nut box' (unlike the more normal plastic ones). The watch is large, approx 47mm diameter excluding buttons (for comparison a GW-9200 Riseman is 44mm) and well made as one has come to expect of Casio G-shock line up. The black resin is a little more matt than normal, the band is double slotted and the metal clasp has a slightly brushed finished. The display is clear and crisp, the digits being slightly larger than Casio's normal offering. http://i1289.photobucket.com/albums/b516/smile1874/IMG_2132_edited-1_zps303b17dd.jpg The 'headline' features of this watch are as follows -Altimeter -Barometer -Thermometer -EL -World Time -24h stopwatch -24h countdown timer -Alarm The altimeter, barometer and thermometer functions of these Casio watches have been discussed ad-inifinitum elsewhere. As long as you understand the flaws of Casio's system they are perfectly useable. For comparison the watch read barometric pressure and temperature within 2% of my home weather station and GW-9200 Riseman. One big disappointment is the lack of barometric reading in the normal time mode - one of the best GW-9200 features is an indication of rise in fall of barometric pressure in normal time mode. This feature was even present on the far earlier DW-6500. The 'red eye' is a simple seconds counter normally, it is only use to show a rise or fall in pressure in the barometric pressure screen. The EL is one of the watches most interesting features. Have tried to capture this in the image, however think my EL photographing skills need some work. Rather than the normal green EL which illuminates the entire screen there appears to be LEDs arranged around the GDF-100 screen which illuminate the screen in crisp white light. The remaining features are fairly run of the mill. World time. Alarm and hourly chime. 24 hour stopwatch and 24 hour countdown timer - two features which are in demand by some. The current time is also visible on these screens. On the wrist the watch wears like any other large G-Shock. The case sat well across the top of my 7 ½” wrist and the strap was well countered away from the watch giving the GDF-100 a snug and comfortable fit. It’s a big watch of course but feels fine on; it lacks the heft and height of something like a GW-200 Frogman. Visually it’s an imposing piece and is instantly recognisable as a G-Shock thanks to its looks and of course the red G EL button. This size may not be too everyone’s taste, it does almost seem to be big for the sake of being big. The LCD display is a slight departure from previous Casio offerings, will have to spend a little time with this to draw an opinion. The sensor protrusion on the left of the case may not be to everyone’s liking, further it may cause issue for those who wear their watches on their right. A size comparison of the GDF-100 with the GW-M5600 and GW-9200 can be seen in the thumbnails below. The watch is not solar nor does it have any waveceptor functions. Two features which are becoming almost expected on Casio’s mid to high end offerings. Only time will tell how long the battery will last with regular EL and twin sensor use. Conclusion Good Large and well made Twin sensor Larger than normal digits Comfortable and fits well 24 hour stw and cdt – both showing current time Bad Large – perhaps too large for some No barometric display in the home screen No solar or waveceptor Lack of button at 2 o’clock seems unusual To sum up another top G-Shock from Casio. It’s good to see the Japanese company trying something a little different. However at the watches price point I’d be sorely tempted to put the extra towards the GW-9200 Riseman which is an obvious competitor. Will I keep the review model? Let me think about it….
  7. congrats! Enjoy your new watch! This is a acquisition you won't regret.
  8. I've said it before and I'll say it again, one of GS's finest designs. I'm surprised there are still some of these floating around. Congratulations of your score! It looks great
  9. Engineer II Magneto S New approach to the protection of a mechanical movement. The A-PROOF® device is a completely new approach to the protection of a mechanical movement. The preservation of the workings of a watch caliber requires it to be enclosed in a casing that protects against the influence of magnetic fields. For many years BALL Watch has focused its research and development strategy on improving the anti-magnetic protection of its mechanical watches. The briefest of contacts with an artificial magnet may be enough to magnetize an automatic movement and cause the complete stoppage of the mechanism. According to accepted standards in watchmaking, an automatic watch is deemed « anti-magnetic » when its operation can resist a magnetic field of at least 4,800A/m without its accuracy being subsequently affected by more than 30 seconds per day. BALL Watch equips its antimagnetic models with specially constructed stainless steel cases which resist ferrite corrosion. Until now, the anti-magnetic casing has taken the form of a soft iron inner structure, consisting of a rear plate and a ring surrounding the movement and the dial. Soft iron, reinforced by the shape of the inner case, channels the magnetic fields and prevents them from entering the movement. This process helped endow the most highly-developed BALL timepieces with anti-magnetic protection guaranteed for up to 12,000A/m. The A-PROOF® device is based on cutting-edge developments in terms of both materials and construction. BALL Watch has carefully selected mumetal – a material never before used in watchmaking – for the development of its new anti-magnetic protection device. Mumetal is an alloy of nickel, iron, copper and molybdenum with very high magnetic permeability, which enables it to attract and deviate static or low-frequency magnetic field lines. In addition to this revolutionary new material, BALL Watch Company engineers sought to bypass the constant imprisonment of the movement in an anti-magnetic cage which renders the caliber mechanism of a watch equipped with a transparent background invisible. The solution: a diaphragm mechanism that extends or retracts at will by simple circular motion of the bezel. In the fully closed position, the diaphragm locks the mumetal anti-magnetic protection cage. In the retracted position, the diaphragm disappears to reveal the movement at work through the transparent case back of the Engineer II Magneto S. The Engineer II Magneto S boasts a powerful and striking look with its case in stainless steel and a robust 42mm diameter, with a thickness of 12.5mm, its black dial, the green circle on the flange – the corporate color of the BALL brand – and its chiseled bezel. The basic hours, minutes, seconds and date functions are ensured by a BALL RR1103-CSL caliber, COSC-certified. The Engineer II Magneto S is equipped with BALL’s patented SpringLOCK® system that guarantees the accuracy of the movement upon heavy shock impact. One of the company’s guiding principles is that a watch should be easy to read both by day and by night. In order to ensure perfect time reading with its mechanical watches even in total darkness, BALL Watch Company uses cutting-edge Swiss technology involving the capture of H3 luminescent gas inside glass micro-tubes on all its models. This technology is a hundred times more powerful than other methods of lighting commonly used in watchmaking. The watch’s qualities are rounded off by a screwedin crown, an anti-reflective sapphire crystal, water-resistance to 100 meters and a shock resistance of 5,000Gs.
  10. I like the thought and creativity behind this piece and how they are standing out between other watch makers, but boy is this piece harsh on the eyes.
  11. One Hertz RG. In 5N red gold The world’s first and only series wristwatch with independent dead seconds The Grönefeld One Hertz is the world’s first and only series wristwatch with independent dead seconds. It features a beautiful solid silver dial and an entirely in-house developed movement with stainless steel bridges and exceptional fine finishing. Dead seconds is where the second hand advances in full steps of one second instead of the usual smooth sweeping action of mechanical seconds. With the One Hertz, Bart and Tim Grönefeld have resurrected this long-neglected horological complication and re-positioned it on the pedestal of high precision. Until the arrival of the One Hertz, dead seconds – secondes mortes in French – in wristwatches was usually derived from constant force devices. The Grönefeld One Hertz is unique among wristwatches in that to maximize precision, its dead seconds are powered by a secondary gear train, independent of the gear train for the hour and minute indications. While the dial is dominated by the over-sized dead seconds, elegantly shaped blued-steel hour and minute hands make for easier reading of the time in the sub dial at 2 o’clock. The hour/minute sub dial is visually balanced on either side by a power reserve indicator at 11 o’clock and winding-setting indicator at 3 o’clock. Winding and setting are ergonomically selected by pushing the crown in, instead of pulling it out, and the winding-setting indicator shows the selected mode. What’s more, the counter-poised seconds hand ‘hacks’ – i.e. stops – when ‘setting’ is selected, to ensure maximum precision when setting the time. The dial is crafted out of solid sterling silver then blasted with brass particles to attain a frosted finish with a slight sparkle. The soft sheen contrasts superbly with the flamed-blued hands, making for excellent legibility. The graceful curves of the displays are complemented by the three-dimensionality of the multi-layered dial, which is beautifully framed by the highly-polished red gold case and bezel. All applied dial elements, including the dead seconds chapter ring, are rhodium plated with circular graining and beveled edges. The bevels are polished with diamond paste to a brilliant gloss to create scintillating reflections of light, echoing the high-end finishing of the stainless steel movement bridges visible through the display back.
  12. I flipped my Sub-C for a Rolex GMT 16710 for the same reason. The combination of the weight and lug shape made it uncomfortable. I wear a 44mm PAM regularly with no issues. Either the older GMT or Explorer 16570 work best for me as far as Rolex sport models.
