1950s Certina "DS" 1st Diver Automatic With Original Gay-Frere Brace

1959 Cerchina "DS" rare 1st diver automatchic model with original bracelet. It is a rare 1st diver with shock resistance and water resistance (200m at that time) by the elastic shock absorber ring installed between the case and the movement. On the back cover, you can see not the famous tortoise mark, but the engraving of "PATENT PENDING" which shows patent pending, the automatic Cal.25-45, and other unique features of the 1st diver everywhere. The black gilt dial with unique indexes is the elaborate construction that can be seen in the Eterna of the same age, and the aging with the texture attracts a wonderful taste. This is a collector's item that comes with a very rare original Gay-frere bracelet from that era.
