I'd look elsewhere for a bidirectional 12h bezel - I think the Seamaster is cool as-is and wouldn't want to mess with it.
One idea is the Halios Fairwind, which is designed with a bidirectional bezel (dive or 12h options).
Another is to buy a cheaper beater diver with a 12h bezel and pop out the click spring - I did that with a Mint Evolutive I bought last year specifically for domestic travel:

Good watch. No date is a huge plus, and its NH35 movement kept better-than-chronometer time surprisingly - a nice bonus for a ~ $350 watch.
(Prob will be letting mine go too, if you want to PM me
