I’m very fond of this watch, I picked mine up during a Macy’s sale for $300: https://www.hamiltonwatch.com/en-us/h69439931-khaki-field-me...

There are few different dial and strap combos, I just ordered a steel bracelet for mine.

It’s a bit thinner than the Seiko 5 SNK803 or SKX007, is a reasonable size (38mm) and the hand wound movement reduces the thickness since there’s no rotor. There isn’t a day/date complication either, just a three hand watch.
