One thing I've often wondered about is why the two-colored bezels? I'm assuming the idea was to separate day from night at a glance, but never thought this made much sense. Daylight doesn't necessarily correspond to 6 am to 6pm and the use of military-time hour indicators on the bezel already indicates a.m. versus p.m. at a glance.
Was the two-colored bezel just for decoration? You've shown your black bezel model and I don't think you lose any functionality with that....
