Two of the four vintage watches I've picked up lately. Another Hamilton (a Model A-517) and a 17 jewel manual wind Waltham are being overhauled.
The first is an Accumatic Model 201A with a calibre 689A automatic movement that I picked up in a trade.
I haven't figured out the model on the second ('Automatic X1'?). It has a calibre 815 automatic movement. $108 on the 'Bay. Wore it for two days and got 36 hours off the wrist.
