Hello all I have a seamster 300m 2018 I sent in for service because it had a cosmetic issue. Is there a significant difference in its accuracy after they open and assemble it again? Thanks.

 

It will run fast without the lint weighing it down, but not enough that I’d worry about it.

 

The watch will be serviced and brought back into the same tolerances - the rate may end up different but will fall inside what the tolerances are for METAS.
