Michael Posted May 11, 2008 Report Share Posted May 11, 2008 I have a SS Daytona, with the 7750b movement, and it has a slight problem where the subdial at 9 will move when in normal time mode. It works perfectly when chrono is running, but when not using the chrono, the hand in subdial 9 moves slightly after the watch has been reset after just 20 minutes. Which gear do I have to freeze to stop the hand moving in subdial 9? Or would it be easier if i just cement the hand? Would freezing this gear/hand cause any running problems with my movement.? Im very happy with this watch, and it gets comments on it almost weekly, but the dam subdial at 9 is frustrating. Any help, or advice is appreciated.

If you freeze that then your whole chrono function won't work, is that worth it ? These Asian 7750's do some strange things. I have one that runs much faster (1h a day) on a winder then when I wear it, on another I have to keep the chronograph running or it will stop alltogether. An older one with seconds at 9 (which is the natural position) has the hour hand at 6 moving just 2 notches when the chrono is off. I think you are just lucky if you get one that works 100% clean and that is especially with the seconds at 6 - that one uses so many gears to switch those 2 subdials. I would not worry about this Quote Link to comment Share on other sites More sharing options...
Michael Posted May 11, 2008 Author Report Share Posted May 11, 2008 Thanks for the reply. i will keep it as is. Incidentally, you mention seconds at 9 being the natural position? Ive seen Genuine Rolex Daytona models with seconds at 6. Quote Link to comment Share on other sites More sharing options...

Incidentally, you mention seconds at 9 being the natural position? Ive seen Genuine Rolex Daytona models with seconds at 6. The current Daytonas, 1165xx models, have running seconds at the 6 o'clock subdial. All previous Daytona versions had running seconds at 9.
