Seiko NH35 date half date tick

[JasperM]

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.
