A rare Certina dive watch. No mention of any DS line on the dial where Certina divers from the 80's and 90's were part of this Double Security (DS) line. Instead there is an Anglo-Saxon depth rating on the dial and Swissquartz. Clearly a Certina diver that was made for the American market. Powered by the mysterious Certina quartz calibre 123.

With a diameter of 28mm and a thickness of only 8mm it genuinly is a small ladies watch. Petite but tough looking though. On an original steel-inox NSA bracelet with an extendable Certina clasp. A nice vintage lady diver from the mid 80's or early 90's.
