Possible crown/gear issue? Moving second hand while changing time

#1 Post by Shawnturner » Fri Oct 06, 2017 2:39 am

Hello Everyone

I have a GMT Master II(c). When I pull out the triple lock crown to change the time (in the outer most position), sometimes the second hand keeps moving while I change the time. If I continue to move the minute hand, the second hand eventually stops (seems to be a gear thing). Happens about 1/3 of the time. Is this normal or a problem?
Any idea, suggestions would be appreciated ,

Thanks,

I didn't find the right solution from the internet.

The stop lever is not reaching the balance wheel immediately in the setting position. Try pulling out the crown from 2nd position into 3rd position decisively to improve your chances that it will hack without delay. The 31s are great movements the only issues I have ever had with them are setting mechanism problems. Not the end of the world.. address the problem when you next service the watch
