Good morning.

I have a friend who needs a couple of items for his wristwatch.

Here's the info he's given me.

It's a Felsa 1560 and he needs a balance staff and a click spring - he mentioned the number 1540 for that.

Also, did an Illinois pocket watch serial number 3159477 have a chrome or white gold plated case as standard?

Thanks for any help.

Michael

Felsa staff: need to know: regular (non shock) or if shock resistant, what kind? incabloc, KIF, etc. Also hairspring collet size must be advised as there are variations. Clickspring not a problem. Felsa movements were used in many brands.
