What Should Be The Normal Calibration Of Eta Movt

[bertieng]

As title said, any idea from the ETA experts? Mine is ETA 2893a2.

Does +/- 45 seconds a day is normal?

Thanks.

I would say 0 to +30 secs per day is acceptable.

I have a rather large collection.

+/- 5 secs a day is actually a lot more common than you might think. +/- 10 seconds a day is perfectly ordinary. Anything more than that and I'd be making adjustments.
