Ticktick Posted May 6, 2014 Report Share Posted May 6, 2014 Hi at all, I've got a question. How many turns does a gen Rolex 703 crown make until it's fully closed from winding position? I'm talking about Submariner and Seadweller watches. Cheers Andi Link to comment Share on other sites More sharing options...
preacher62 Posted May 6, 2014 Report Share Posted May 6, 2014 About three turns. Never really counted them. Link to comment Share on other sites More sharing options...
freddy333 Posted May 6, 2014 Report Share Posted May 6, 2014 Depends on the condition of the gaskets and depth of tube in the case. Generally, anywhere between 1.5-3 is about right. Link to comment Share on other sites More sharing options...
alligoat Posted May 6, 2014 Report Share Posted May 6, 2014 After pushing the crown in to engage the tube threads, it was 2 turns on my gen 16800. Link to comment Share on other sites More sharing options...

alt.watch.obsessive Posted May 7, 2014 Report Share Posted May 7, 2014 Three feels about right. And as far as I can tell it is strictly luck if the coronet lines up in any way, even on a gen. Link to comment Share on other sites More sharing options...
Mendota Explorer Posted May 8, 2014 Report Share Posted May 8, 2014 ^ True. I think it has to do with the orientation of the threads on both the crown and the tube and how they align, as well as how much compression there is on the o-rings. Over time the o-rings will compress and you'll get slightly more rotation on that last turn, which could help line it up a bit or push it farther out of alignment if it used to be aligned. So even if it is aligned now it may not be a few years from now as those o-rings wear. MD2020 lined mine up perfectly when he installed my gen crown on my PT 1680. I had no effing clue how he did it and he told me at the time it was just a little bonus he liked to do. It makes me wonder if he even did anything at all and if it wasn't just luck of the draw with the threads lining up like that. Or maybe he did something with the tube to unscrew it or screw it in tighter. I'll never know. It screws in like butter, though, so that's good.
