Owens Posted February 3, 2007 Report Share Posted February 3, 2007 Hi, I just received a Tag rep with 7750 and I went to use the date quick set and it worked great. Then I went to use it again, and it would only turn about half of a number. Any ideas? Thanks, Dustin Quote Link to comment Share on other sites More sharing options...
Bignasty Posted February 3, 2007 Report Share Posted February 3, 2007 You have to be careful with the 7750 on date set. If you try to set the date when the time is between 10 pm and 2 am you will damage the date mechanism. The date changes over this 4 hour time period so if you go forcing the change it will jam the movement causing it sometimes to stop often. This is not only true on the reps with this movement but also for any Genuine watch with the 7750 movement or some modified form of it such as Breitling's Calibre 13. As a rule of thumb when setting the date always first roll the time down to the 6 position. Then set the date one day before your desired date. Then roll the time around appropriately to get the right date and correct AM/PM setting. Sounds complicated but it'll guarantee your movement will last you a very long time. Also while I'm making recommendations let me make another. Never reset the chrono's except for when the second hand is between the same 4 hour period. This will ensure it resets to 0 properly every time. If you reset out further than these positions you run the risk of the second hand pivoting on its shaft. Hope I've not overwhelmed you but I own many of the 7750 movement watches and I know the precautions to make them last as long as possible.

vmena Posted February 3, 2007 Report Share Posted February 3, 2007 bignasty... is this the same for old and new Asian 7750's? Quote Link to comment Share on other sites More sharing options...
Watchmeister Posted February 3, 2007 Report Share Posted February 3, 2007 Yes it is relevant for all 7750's. On the chrono reset issue usually Ziggy glues some or all of the hands (I don't remember) to ensure proper reset. Quote Link to comment Share on other sites More sharing options...

I followed his instructions and glued the [censored] (the bit of the hand that connects the hand to the stem) to the hand and then put it back on.
