Dear,

I have a watch that had a broken 4R15. I switched it with a NH35. However the day wheel is different so I switched the 4R15 wheel to NH35. I however sometimes ticks over only half the date as seen in the picture. Sometimes it ticks over the day perfectly, sometimes even worse than on the pictures. Did I do something wrong? Is it just not compatible?

 

Thanks for your time!

This is a tough one to diag ? ,  Fault at date disk ?. 

 Did the date line up in 4R15.

Did you grease the groove date disk fits in?

On these Seiko all calendar moving parts are made of plastic, on which due to its self lubrication properties no additional oiling is needed or desireable. 

A tiny adjustment on the date jumper may be needed after observation with the dial removed.

      Converting Pocket Watch to jewels

      By nevenbekriev · Posted

      Daniel, I guess You actually asked if the accuracy of the watch was improved after jewels added. One would not expect such accuracy improvement. The watch accuracy depends on many things and most of them are related to the balance and escapement. Well, it depends what is considered to be a no jeweled watch. If this is pin pallet watch wit cone balance pivots, then, believe me, replacing balance staff with one with cylindrical pivots in jewels will only worsen the things. Cone shaped pivots in cup bearings actually work better than  cylindrical, the only problem is that they wear faster. And, it will be hard to impossible to replace the pallet pins with ruby pins... The watch accuracy depends maimly on the balance and escapement adjustments ad it is no related to the presence of jewels. Adding jewels to the train wheel bearings may only lead to some amplitude increasing, and it is not sure too.

      Thank you so much! I'll experiment a bit with the UV glue and chalk and maybe eventually try to fill the hole.  I'll report back!

      How did you know to shorten the bottom pivot and not the top? It sounds like something is rubbing when in the dial up position.

      Pocket watch mainspring replacement

      With apologies for taking advantage of your kindness in responding, would you be able to indicate what sort of additional info is needed & where on the watch I might find it? Do you have any suggestions as to what Cousins might mean by "a normal  bridle"? ( their website says they can't provide any technical information....)

      Yeah, it looks exactly like that, but the balance staff pivots was long when fit into the jewels, so I took some  bits shorten it from the bottom pivot but  when  I made the movement run  on all position and all the other position works fine but not on dial up position.  and im not getting any reading from my timegrapher So what do you reckon the issue could be do I need to shorten the bottom pivot more and also a notice the balance rim is really close to the center wheel teeth  feel  it's catching the rim.
