SH3135 and Manual Date Change

[lilmoogz]

Hi guys,

I’ve read the SH3135 requires that the date not be changed during certain times to prevent damage.

Is this true? If so what are the times I should avoid manually changing the date?

My SH3135 has a gen date wheel in it if that makes any difference.

Thank you kindly for the help!

on mine, if I change the date between 11h30pm and 7:30am, I feel a little friction (very light) and the hands move a little at each change of date so I do not change the date during those hours.
I changed the 623 and 625 parts for gen that are supposed to correct that.
I checked without the dial and the date finger touches the DW until 7:30 am.
to be careful I advise you to not change the date between 10pm and 8am but the experts of the sh3135 can advise you better than me

General rule for any mechanical watch with a date is to not change the date via crown between 10 pm and 2 am as the date change mechanism is engaged and can potentially be damaged. This is true for genuine movements also.

Especially true for many older Seiko movements. I forgot this last week and messed up my 1967 8346C. Kicking myself.

Ouch. That sux. Hopefully you can get it repaired for a reasonable cost
