In the early 1970s, the Jenny Caribbean was one of the first timepieces to be guaranteed to a depth of 1000 metres. They patented their case in 1964 and a few years later licensed its design to other brands including Fortis, Heuer, Squale and Philip Watch. A special case made from a single steel monocoque, with no removable case back. To access the movement meant removing the bezel, the crystal, hands, dial and crown. This is what gave the watch its reputation amongst serious divers of the day.

The specs are as follows: an excellent case with indexed black and yellow bakelite enamel bidirectional rotating diver’s bezel, signed ETA Swiss automatic movement with quickset calendar function, excellent refinished black dial with luminous markers, luminous arrow hands with sweep seconds, unsigned original screw-down crown. The monocoque stainless steel single-piece case on this vintage diver is in great condition with minimal wear. The acrylic crystal is in excellent condition. The crazy bezel made of yellow and black bakelite is also wearing well.

The case back is also signed, “Philip Watch, Chaux-de-Fonds and it comes with a Philip Watch box (sadly no papers).

As vintage divers go, this is as good as it gets. The distinctive case, the dial looks great through the domed crystal – a piece of 1970s history.
