Ive got 2 broken watches in my box,a UN thats never been worn with a second hand that came off but what i need your help with is my panerai. I dont remember who its from but for the first few months it ran ok,then all of a sudden it started running erraticly.i kept trying to get it going but in the end it just gave up and so did i. Tonight i thought id get my box out of the cupboard and have a look at what id like to wear since my PO got trashed(bike accident). i noticed the panerai and thought id take the back off.......not that i know what im doing....i was just going to shake it....lol. When i did get it off, i turned it over and this small piece fell out(picture) Anyone know what it is? The really wierd thing is.....my watch is now working perfect,chrono and all.ive put it on a rubber panerai strap i had lying around and im a happy teddy but id love to know what part fell out. cheers
