GenTLe 1,512 Posted November 19, 2014 Hi All, I recently bought M2M here a Noob sub-C v3. The watch was nice but unfortunately it has a problem at date wheel system level (and the seller told me he wasn't aware...). Practically the date doesn't change by itself and only operating with the crown with quick date set it can be moved on. I unassembled the movement and I got that the problem in the Intermediate date wheel (part nr. 41 in the eta charts). Using the time setting function to quickly make the time to pass for the movement, I've seen that while the hour wheel moves the engaged Intermediate date wheel, and this last one transfers the movement to the date indicator driving wheel, the intermediate DW gradually lifts/tilts itself (on the side where it engages with the hour wheel) to the point that it loses the engagement with the date indicator driving wheel which, having a spring system, is being counter rotated to the rest position. I already tried to replace the Intermediate date wheel, the date indicator driving wheel and even the minute train bridge, but the problem is still there... If, with tweezers, I keep the intermediate DW in position all works normally. Any advice, please? Thanks, GenTLe Here some graphic (don't consider the 2 light blue big arrows which are part of the original graphic and yes, the minute bridge was properly fitted) Share this post Link to post Share on other sites
SSTEEL 0 Posted November 20, 2014 I have come across similar, and its usual one of two reason the above happens. Its either the date wheel is not true, and maybe slightly kinked, or the main plate post that the intermediate sits on is too short/worn. If the latter, then you need a new main plate.

I was hoping in a different solution even if I came to the same conclusions after I tried 2 different DW :( Well, now I should look for a no date rep using the same movement in order to see if I can do a swap, or purchase a new movement and spend these 80€. Bummer :( Share this post Link to post Share on other sites
SSTEEL 0 Posted November 20, 2014 I may have a spare main plate I can give you, I can send it a long with your watches once I have fitted your AR crystals. Share this post Link to post Share on other sites
