Unbranded skeleton movement

[fnick]

Hi all

Here is an unbranded skeleton watch that I have just bought.  The winding stem is broken and there is no crown. There doesn't appear to be a movement identifier which I was hoping for to help me source a new winding stem and crown. Any help will be much appreciated! Here are some pics.

And a pic of the broken winding stem

I did see a similar watch under the Citron brand but can't be 100% sure.

Thanks, Nick

Probably Chinese, you can measure the stem you have.

Thanks Richard

The stem is 0.6mm wide. At least the part that the crown goes onto. Is that enough info to order a new stem and crown and look a pics of the stem so check that the part that goes into the keyless works matches the one I have? Asking out of ignorance!

Cheers, Nick

I can't get windingstens.com to open but you need a  few measurements.

The movement is so called 'Tongji', standard chinese movement. The stem can still be used with the help of extender.
