How to adjust an asian 7750

Recommended Posts

Dear all....dear Rob,

let me first stress: I DID USE THE SEARCH BUTTON...with no result, sorry! ;)

I have a nice watch with an asian 7750 in it, unfortunately the watch runs like [censored]....it is way too slow!

So my question is how can I adjust the watch, what are the wheels and adjusters I can play with?

(the watch is -1min in only 1 hour)

Thanks for helping out....

Without a watch analyzer, your only guessing at what is being adjusted.

The beat is the most important adjustment, and the only way to check it and adjust it is with a timing machine. You can move the regulator arm and make the watch run faster, but again, you have no idea what your adjustments are, since you don't have anything to tell you how fast or slow it's running.

If you have a loupe, a good light, #2 tweezers, etc, and some experience working carefully, you can move the regulator arm on the balance, but its attached to the hairspring and you have to be very careful. THe regulator arm is in between the stud arm and the center of the watch, you move it CW looking at it.
