This is a vintage watchmakers lathe made by the American Watch Tool Company. It is an authentic precision lathe designed for horological work and uses American WW collets measuring 0.312 to 0.313 inches (7.92mm to 7.95mm), so 8mm European collets will not fit.
This item is in very good condition and I have given you clear images of this lathe from every angle to help you see the quality before ordering.
If you are not sure if this will fit your watchmaking setup or if you have any other questions, feel free to email me at Sales@TheWatchLink.co.uk. I'm happy to help!
