Greetings all,

I recently bought a "Vintage AAA 21 Jewel" Orient on the bay for £10, which was refunded by the seller 'cos it doesn't run.

On the back of the case the serial is CN 469AA2G 8A CA, which corresponds to the 21 jewel, 46941 movment.

I've opened it up to fix it, but knackered the hairspring in the process.

BUT..

The movement has 46961 25 Jewel printed on it.

Obviously a swapped movement and case.

Question: does anyone know if parts esp the hairspring assembly is compatible across both movements?
The 21 jewel seems much more common on the 'bay.

Cheers
