The watch is running but the date does not change as it should.
Lovely looking movement.Movement out of the case.I start by removing the electronic unit very carefully as I do not want to damage the coil.Underneath the electronic unit you can see the hacking lever.To prevent backlash in the movement there is a tension spring that engages with the escape wheel.Removing the train bridge reveals the gear train.I now turn the movement over to start on the date and setting mechanism.I remove the day date spring revealing the date mechanism.Removing the plate for the date mechanism you finally get to the setting mechanism.The parts have been cleaned and the movement is ready to be put back together.I start by putting the balance jewels back in place.I turn the movement around and fit the center wheel.I then put the setting mechanism back in place – notice the long spring that provides tension for the date quick set. The plate for the date is also back in place.I now put the gear train back in place.The pallet has a little magnet attached to it. This cool feature is to create draw towards the banking pins that are made out of metal.Here you can see the recoil spring engage on the finely cut wheels on the escape wheel.The balance is put back in place.The day disk should be riveted onto the star wheel that engages with the spring, but it is loose and causes the disk to move out of place every time the date changes. I do not want to try and re rivet this, as the disk is very thin and delicate. I align the date correctly and use s small amount of super glue to fix the disk onto the star wheel.The movement goes back in the case and is looking good.I made a little isolation cap so the battery fits a little bit more snugly, I suspect it should have had one and that it is missing.I really like the dial design of this watch.The case diameter is a little large for my wrist, but with a leather strap and the hidden crown it just about makes it wearable;)
