This is one I've been considering. I would have suggested it in the other current watch thread, but the OP indicated that a metal bracelet was important, and I'm not sure that B&M provide one for this watch (they might; I just don't know).http://us.st11.yimg.com/us.st.yimg.c..._1916_67919141
For me a dress watch means one with a leather strap. In addition, it must have a diameter smaller than about 36 mm. (excluding crown). It should have a plain, narrow bezel (without, of course, numbers such as those found on diving watches, or any other quasi-functional characters), and elegant lugs--not the large mass found on some watches at the lug ends. It should have very few complications; I'd draw the line at (a) a second hand and (b) a date window--i.e., I'd allow those, but nothing beyond. Many think that a white (or light silver or champagne gold) dial is preferable for a dress watch, but I'd probably consider black too, although not a darker, colored dial. For me, the decision between quartz and automatic has no bearing on a watch's suitability for dress use--they both look the same, after all. My own preference is quartz because of the vastly superior accuracy, but watch purists go into the shakes at the idea of quartz.
The B&M Classima above is available in a number of versions, and some are smaller than the 36 mm. diameter noted above. They are available in quartz and automatic versions, and can be had for good prices on eBay or online suppliers like Joma, from whom the above link was taken, Overstock.com, and many others. You should be able to pick up a quartz Classima, in either silver color or gold, for under $1000 and an automatic to your liking for less than $1500, perhaps much less.
