What Movement is This?

Hi guys. I just took this movement out of my mystery date Herma. Does anyone know who produced this and what the 87 means? I hope it doesn鈥檛 mean 1987 because the dial looks so much older than that.

Is a Parrenin caliber 87.

Ah! Thanks. Now comes the hunt for spare parts! Hope I haven't gotten in over my head.

What parts does it require?

It's getting much more difficult to acquire parts for watches that age nowadays. Many times need to manufacturer them.

New crown (whole thing), new mainspring, barrel, balance wheel and hairspring assembly

I ordered a new crystal and I think I ordered the right mainspring too. Need to find the right size winding tool so I can install the mainspring in a new barrel

Jesus. That's a bit much. Would have been better to use that one for parts and just aquire another better condition movement.
