I have a Frederique Constant Slimline Gents FC-220S5S6B. It is a quartz watch with date, 5mm thick. I find it very comfortable to wear that it worked its way to becoming my daily watch. I bought it new for some Eur300 but you can look around maybe an inexpensive used one becomes available.

FIL has an automatic version. The gold plating seems to wear off with regular use. Too bling to my liking. I like 2-tone watches. I recommend that you save up and buy it new.
