Im kinda confused about the accuracy of mechanicals, I keep getting varying answers.
How many secs does the avg mechanical (not COSC) lose or gain a day?
Is +/- 10s normal? Ive been told by my jeweler that +/- 2 or 3 secs a day can be expected.
Also, what is the range for a COSC certified watch?
And after wearing the watch for a while and getting it regulated how much more accurate does it become?
Sorry for all the questions but I would be grateful for some solid ans.
