I bought this ladies watch (to be carried on a chain around the neck) more out of curiosity, as I have seen this model as a wristwatch before. Diameter is 39 mm.
Opening the case, I was somewhat surprised. The mounting of the movement can't be made any cheaper. When winding up the watch, the movement is not staying firmly fixed in place. The back-cover needs a closing press to get it back on, like on a waterproof watch, but there is a hole on the side where the winding stem is moving around from side to side when winding up. It has acrylic glas of whatever quality. The gold plating would not withstand a firm polishing.
On the other hand, the movement seems to be not too bad, provided it really has 17 jewels and all with a function. The time is kept accurately. I have excellent readings on the time scale in various positions, with a beat error of only 0.1 ms.
21,600 half oscillations. The amplitude is 289 degrees, but that can be different if I would know the calibre and then the lift angle, if available. Perhaps someone recognizes it.
The chain which came with it is a shame for the human race. I dont want to blame the watchmakers for that, it was certainly added later. If I want to give this thing to my wife, I will have to buy a real gold chain for it (333 minimum). And then, as you want to have a look at the watch from time to time, the chain cannot be too short, adding to the price inch by inch.
So, good movement in a cheap case?

Since it isn't a clock thread moved. Not a fake. Watches of the 60s looked like that. Movement spacer and the way of attaching the watch is not unusual.

Nice find.

Sorry for putting the thread it into the wrong place and thanks for the reply!

After running a while, the readings are even getting better. If it is really fast by 57 s/d (which I will see later) I leave it as it is, as I do not want to open it and squeeze it together again with the closing press, especially as I do not have the ideal die for that size. Of course, without knowing the lift-angle, the amplitude can be somewhat different. A 0,0 beat-error is very nice. I also have no clue what to move/turn where on this type of regulation.

The watch has a Peseux Cal. 7040 in it which is actually a decent movement: bidfun-db Archiv: Uhrwerke: Peseux 7040 ...so it is a cut above the large-watch-with-tiny-ladies'-movement-to-get-rid-of-movement-old-stock watches of the 1970s. In order to regulate the watch, you have to nudge the thinner of the two arms on the balance cock. If the watch gains, you have to nudge that arm towards the thicker of the two arms. However, regulation and adjusting usually involves a little more and it may well be that your watch requires a full service (i.e. once the watch is regulated closer to ±0, the trace may start to wobble about rather than consisting of a really straight line - a wobble indicates the need for servicing).

Thanks very much for all these valuable infos. I will adjust along this line and see what comes out of it. I was also able to find the lift angle now, which is 52 degrees for the Peseux 7070.

Adjusted and closed. Thanks again for the instructions!

Pretty nice figures now.
