Blandford S.A. Ocean-Diver 25 Atmos "Squale Case"

Squale famously manufactured diving watch cases for a variety of different companies, as well as manufactured their own watches, and still do to this day. During the 1960s and 1970s, AKA the Golden era of dive watches, Squale provided cases for Ocean Diver/Blandford S.A., Sinn, Blancpain, Heuer, and Doxa to only name a select few. Squale also supplied the Italian Airforce's "Folgore Brigade" which was a parachuting squad and the Italian Navy’s Diving Corps with timepieces during this period.

This specific Blandford S.A. Ocean-Diver features a slightly asymmetrical case manufactured by Squale with integrated crown guards. The watch itself is very aesthetically pleasing and features many unique stylistic differences compared to what we traditionally see as a dive watch. This watch would fit perfectly into any collection and is an excellent option for everyday use.

The previously lightly polished case retains its angular profile and shows some light wear. The original blue bakelite is in stunning condition without cracking or any major wear signs. The case retains its original crystal that features an internal cyclops. The factory caseback engravings remain clearly visible. The watch will come supplied on a 2pc leather strap.


The grey sunburst "Squale" signed dial is both gorgeous and unique, the dial itself remains in excellent vintage condition. The original tritium lume plots have aged to an excellent golden coloration, under U.V. light inspection the lume plots exhibit no degradation. The original tritium hands match the dial perfectly, under U.V light inspection the sweep-seconds hands exhibits some minor lume loss, the hour hands exhibits very minor cracking, and the lume of the minute hand shows a small repair towards the top of the hand.


None. Watch is running and keeping time perfectly, previous service history is unknown.
