Thank you all for your honest replies, I have definitely come to the right place.
I've been put off a little by the Oris watches because the red paint on the rotor can start to look a bit shabby on some of the older watches.
So Oris is out unless someone has a very convincing argument . Oris out.
The Sinn looks fabulously clean,simple and practical. Unfortunately on that particular model the bezel can turn either way ! A big no no for scuba use on hollybobs.
I am going to look more closely at the other sinn models though, thank you Der Amf for making me notice them.
Omega seamaster, a great watch and a safe bet for holding it's money but far too many of them around. Seamaster out.
I'm not sure of the Tudor watches, I dunno tell me if i'm wrong but I allways think not quite rolex so a poor mans rolex.
Please do tell me if I'm wrong though. Tudor out.
