The Aquadive 1000M vintage diver watch under the company Jenny. It’s a monobloc case, meaning it’s a one big piece of steel case.
When Jenny created the Caribbean 1000, it was the very first 1000m dive watch and the patents were first registered in 1964 with a tripple safe one piece case.
It was later branded by Jenny for Philip Watch, Jaques Monnat, Jaquet Droz, Ollech & Wajs, Aquadive, Fortis, and probably some others.
Today the Jenny Family currently own Doxa.
