I'm on the hunt for a daily driver and have $600 to work with. Things the "do it" for me are: 40mm or less size, hackable automatic, applied markers, not too chunky, color scheme that works in a casual as well as semi-formal scenario. Not essential, but I like a nice beveled chapter ring, screw down crown, decent lume. Not opposed to second hand. Would prefer swiss movement, but in the right circumstance, I'd consider Japanese.
Thanks in advance.
