I personally dislike 3 o'clock date windows...or date windows at all...on dress watches in particular. Therefore that wouldn't be the watch for me. BUT I think Tissot are the sweet spot of good value for ETA-based Swiss watches: simple, clean designs, nice enough finishing and no pretensions of exclusivity in the price (I'm looking at you, Tag Heuer, and a dozen others). I bought one for my son. I am not blessed with any expensive watches - the most "prestigious" maker I have is modest Omega, in a cheap and elderly form at that. So this thread isn't just about dick-waving. Promise.
For me, it depends on the dress watch. There are some with a date window (at 3 o'clock) that I like and some without that I like. There are others of both that I dislike. However, I suppose the purest of the pure dress watch should probably be without a date window at all.
