  1.  

    The problem is always parts. No parts = a doa movement sooner or later.

    Yuki etc 3135 clone parts are n/a. Very few genuine parts will work other than date wheels/dials.

     

    Yuki takes a lot of gen parts.

     

    Besides... movements with no spare parts become spare parts :D

  2. I recently had a Big Date on the work bench and the gear ratio is very tricky. The date should run from 01 to 31 and start again from 01.

     

    Someone probably already worked on your watch and didn't know what he was doing or it happened in China.... To adjust it you need to strip it down and adjust the interconnection of the gears and date wheels.

  3. I used a caseback opener to rotate the outer ring so that one by one the screws lined up with the stem hole where i could remove them without the threads stopping them.

    Then after a bit of fiddling i got the outer ring out then the movement was in my hand.

    Thanks for your excellent advise and and responses everyone, That had me stumped.

    Job well done! 8)

  4. A2836s is are new movements. The Swiss ETAs that come in our reps are mostly NOS or old salvished movements. Both need service in principle.... Buy a Swiss sealed ETA movement so you know it is fresh or buy an Asian clone and have it serviced would be my advice.
