Jenny Caribbean is a dive watch but is also significant as a vintage watch. Jenny appears to have made watches for only about 10 years from the early 60's to the early 70's and they are accordingly rare and sought after.
The basic movements were ETA to which Jenny added special cases, dials and bezels.
Jenny invented the triple safe one piece case in the early 1960s and issued the first 1000 metre rated diver which ultimately lead to the Omega Ploprof.
My research shows that Jenny was probably assembled by Ollech & Wajs under a reciprocal arrangement that allowed O&W to sell the Jenny patents with their own branding.
The evidence for this is that whilst it is well known that Jenny owned the patents, there is no evidence whatsoever that Jenny had a watch making facility. O&W ofcourse had a well known factory.
Moreover, the Jenny divers came in some very unusual shapes and only the O&W Caribbeans can be found with exactly the same unusual cases.
The Caribbean range included Super Water Proof Divers rated for deep water use between 200 metres and 2000 metres, and Dive Chronos rated for use in more shallow water.
The Jenny Caribbean 1000 came with a decompression table bezel and as we have recently cracked how to use it in the WUS Dive Watch Forum I can tell you it had no purpose other than underwater use.
The extremely rare Jennys are the Caribbean 1000 in Orange or Blue from 1963.
Here are photos of them. They are wanted dead or alive, and have major collector value as vintage watches.
If you see one, PLEASE let me know
