Yeah definitely try it on, its such an awesome watch and i still cant get over how comfortable it is! But yeah divers just have their own awesome vibe and i use it to time things quite often which is a plus for divers.
I used to own the 42mm polar explorer II and I loved it! However for me the 39mm size of the BB Pro is pretty much perfect so even if I still had the explorer II each would have had its place in my collection. The Explorer II being 42mm and a full on modern watch in practice is quite different compared to the smaller, vintagey yet not too vintagey style of the BB Pro. Also the bezel font makes a pretty big difference in how it feels on the wrist. So I say if you want the BB Pro, try it on and get it!
