Hey guys, Have a question: I have a brand new Moonwatch and I recently noticed when the power reserve is at zero and the second hand is stopped that shaking the watch seems to give the second hand maybe 3-5 seconds of power without any winding. I'm just wondering if this is normal behaviour or should the second hand not move at all unless I wind it?
Shaking a stopped watch is definitely is not normal behaviour. Second hand moving a few seconds is ( you will notice in the video below that shaking will move the balance ) Reminds me of this video of a guy who claimed his watch was broken
Ok so it's normal. I'm not shaking it like a polaroid picture, just a slight shake when I was picking it up today really. Thanks for the reassurance.
Clearly, the mainspring is not 100% run down when the balance wheel stops oscillating. There is enough residual power left in the mainspring to advance the train wheels for a few seconds, when moving the watch in a manner to re-start the motion of the balance wheel. I find it difficult to contemplate the sequence of events that would keep the balance moving until the mainspring was totally run down. Maybe a mainspring breaking........IF it broke toward the inner end of the mainspring.
