·Without more pics and a gander at the movement it's all a bit of a guess. You've posted 482 times so you must know your onions a bit;
Mid 60's (?) Seamaster Deville ..Stainless Steel case, non original strap, possible original crown (from what I can tell from the pics).Original dial (i think) in good shape...What do you think it's worth?
I think this must be a 165.0033 or a 165.002 but I can't be sure. I'm thinking that if I'm going to bid on this it won't be more than about £300 given the risks. Add £250 to that for a service that will probably include some parts and if I can get away with the thing running well and looking good for £550 I will have done OK. That said, unless I see images of the movement I'd probably be wise to pass on it.
