Hey josh. Sorry but I can't really answer all your questions. Have you seen the watch in flesh? This is one of those watches that u either love it or hate it. Purists thinks it a lousy re-make with faux patina. I personally think its a brilliant re-production. I'm a serial watch flipper and has flipped tons of watches including rare vintage pieces. None has tug my heart as much as the 300MC.
I personally think Omega watches are made to be worn with straps. They look amazing with straps. A watch is like a statement, a reflection of your style, your likes.
The bracelet scratches very very easily.
Take me your time to hunt for a decent used piece. If you keep thinking about it after seeing it in flesh. That's the one! Happy hunting!
