Another one from my collection. This time it's a dark blue model from February 1970. An early version with a notched case and 6139A movement. Serviced and running great. All functions performing as they should. Inner rotating ring has some sun fade. The case has a few normal scratches from 50 years of use. All gaskets are new and crystal has been replaced with new 1:1. I have the original crystal if the buyer wants it. Comes on a new rubber "tropic" strap.
