I sold my AT 2000 - 3568, to help fund a purchase of another watch.
However, I missed once it was gone. I liked the quality, the sturdiness and the very well executed finish. It was utterly dependable, and the ETA2892A2 movement was extremely precise - with only about +1s every other day.
So I decided to buy the new 3290.
It is even better made, the ingenious bezel is a joy to use, and it uses the same very solidly made ETA2892A2 movement. Which is a good thing. You'd want something reliable when you buy a diver. A delicate in-house movement, is better reserved for dresswatches and complications, in my opinion.
IWC could have used their own 80110 calibre - its a lovely movement (I know 'cause I've had one under a display back on the Vintage Ingenieur), but it would have made the 3290 bigger and heavier.
One little thing I like about the new Aquatimer, is the flat back (the previous one had a raised back), because it makes the watch less wobbly on the wrist, and a tad more discreete. The legibility is beyond reproach, and the comfort excellent. As always with IWC.
Here's an image of the different versjons of the Aquatimer 3290. I opted for the 3290-4, on bracelet with silver dial, but I bought the rubber strap as well. They come off easily, thank's to IWC's proprietary quick-lock-system, making swapping bracelet for rubber a three seconds job per side.
Would I recommend the 3290? You bet. I find the overall finish and appearance more appealing than a PO or Sub.
