HOW TO ADJUST VALJOUX 7750 TO BE FASTER


Recommended Posts

Yes the part you have circled is the regulator arm and if the watch is running slow you need to move it toward the + this will move the regulating pin and in effect shorten the hairspring making the watch run faster. You should be very careful and gentle when doing this, I would be tempted to move it directly to the centre position because it has already be adjusted to run slower.

Has your watch been running accurately up to now ? it may be time to service the movement.

A watch timing machine greatly assists any adjustment of this type.
