Minute hand problems....

Question

This is a project I started a couple of years ago and need to finish it once and for all. The second hand runs fine but the minute hand seems to stop after about 10 minutes. I thought maybe it had to do with the lever not sitting problem and have tried tightening it down but still can’t seem to resolve. I am continuously having to reset the watch after every ten minutes that it runs and then stops. Any suggestions?422e570a91075b90b612c7f05f9ea7d9.png

See below... I had to think about this a while - I always get it mixed up, but I still say canon pinion holds minute hand :)

Ha! The image I just posted shows the seconds hand attached to the third wheel! That's not correct - seconds are attached to the fourth wheel!!!

Yes and no.....

In a sub-seconds or a direct driven centre seconds configuration the seconds hand is indeed mounted on the fourth wheel. But in an indirect driven centre seconds configuration (which is what your illustration appears to be) the seconds hand is mounted on its own pinion which is usually driven by the third wheel.

This is a sub second. And to update, after staying up till about 1 o’clock this morning working on it, the watch is running better but still not perfect. Still the occasional stop but so far this morning it’s been running since 6:00am. Still not sure why.

Crap, you are correct. It's the gear over the pinion that holds the hour hand...I should know this:)
