Here's a nice pendant watch, 1967 and with a case ref of 2720. There is an engraving on the back, but otherwise this is a very clean example. Almost looks like something right out of the 20's at first glance.
This family of movts had a very wide range, and this is the one without any second, sub or centre. Glucydur balance and KIF shock setting.
