Amplitude Change With Setting Watch

[jdrichard]

Ok, my current problem is the watch slows down unless I set the watch, which turns the cannon pinion which turns the minute and hour wheel: using a bench key. Is my problem friction with the minute and hour wheel. I do have the dial on with the dial washer.

been a while since on this blog:)

using a bench key

It would've been nice if we had a picture of the exact watch. On the other hand You gave us a clue bench key. Typically in situations where people are using a bench key when the watch is out of the case the watch will go into setting mode. This is because the case has a sleeve which holds the stem in either winding or setting mode. When the watches out of the case it goes to into the setting mode. The problem with being in the setting mode out of the case is as you found out the watch doesn't have enough power to power all the setting mechanism. But some watches do have a method of putting them bac.

k in the winding mode out of the case we would need to see the exact picture of this watch to see if it has that. Otherwise the only other solution is to put it back in the case

 

 

 

It would really help if you gave us a picture but it did give us a clue. If this was basically a really tiny little pocket watch then typically when the pocket watches out of the case the watch goes into setting. Running a watch in setting mode would have a similar effect to what you have in other words you're trying to drive the entire setting mechanism. Some pocket watches had a way of putting it back in running mode out of the case otherwise try putting it in the case and seeing if that solves your problem.

 With low wind, and stem in set position, slowly turn the hands anticlock , if this stops the watch or reduces amplitude ( sometimes the watch runs backward ) the problem is with the  parts you mentioned or locating pins belonging thereto or the minute train bridge if there is one ( anywhere accross the entire minute train  ) and if so, then turning clockwise would enhance the oscillation.

 Crown pinion remains engaged with winding wheel, when stem is in wind position, so a fault thereon can also introduce friction into the rate, there you have crown pinion, winding wheel ,,,,etc.  for instance there is a jewel and pivot embeded under the crown wheel, the pivot can rub underneath the crown wheel,  affecting the power in gear train.

As John says , helps to know what movement your talking about.
