bull's eye pocket watch help.

[mattbchicken]

So I have an old cheap bull's eye dollar watch that I want to practice on. It seems to start running when I have the crown pulled out with a little counter clockwise tension, but stops soon after letting go. would love to understand what could be going on for learning purposes.

 

Thanks!

It's normal that an old watches do that or simila symptoms when they are dirty inside, and/or oils have drie or congealed, in other words it's gummed up.

The repair is called servicing,  that is taking them apart, clean everything, inspect all parts for wear or faults,, apply correct lubrication,  reassemble and veryfy every function as you go, final check over a couple of days, and time regulation,

If you want to properly learn how that is done have a look to the high quality training for beginners offered by our Host Mark Lovick: Watchfix.com

Possible broken mainspring.

You are supplying power through the minute train when you get it to run as you say you do.

Hi  Both jdm and Joe have coverd the problem which could be either or both, A pocket watch is just a scaled up wrist watch basically but a few pictures of the watch in question would be a help.    thanks.
