Hi,
I would suggest you take a look at Sandoz, provided you want a decent mechanical movement. They use the ETA 2824.
Have a look at Poor man's watches for sale

or contact Terence at www.watchuseek.com (just run a search for Sandoz in the forums and find his examples in the sales forum. I dealt with him and he's ok (best prices for Sandoz around)
Cheers
Luca
