The Aquadive 709-1 (Disco Sub) was made by Jenny in the early 1970s. With a massive 50mm round monobloc case and a 3mm thick crystal loaded from the front, this watch is rated at 1000m water resistance without the need for a helium escape valve. The Aquadive brand was sold in dive shops as opposed to typical watch retailers, making it a true diver’s tool.
