Dress watches are watches that can disappear under a shirt cuff or simply look very elegant. Dress watches often have a leather strap, but this does not have to be the norm. A stainless steel watch in 36mm can be a dress watch just as well as a watch with many complications on the leather strap, but which is 42mm in size. In short, dress watches are watches that, as the name suggests, go well with a suit.
