I like the watch a lot, though some versions more than others. It is interesting to see a certified chronometer without a seconds hand, you do not see that very often.

I also like the range of metal and dial variations--they all look worthwhile! Obviously I'm a bit concerned about the size, but I'm eager to try one on. If they don't wear too big I'm a pretty likely buyer.

And they should have made these watches manual winding instead of automatic: the thickness shouldn't be above 12 mm with only two hands, really. Just my opinion, of course.

they've made a good job except for the thickness. A two hander should be below 10 mm (and manual winding for me). Best, Emmanuel
