IWC produced the Aquatimer in 1966/67 for the first time as a divers watch for the new fashion of underwater diving for sport. As well as having a Master Compressor case enabling it to be water resistant to 20 Atmospheres it had the innovation of twin water-resistant crowns, the second turning the calibrated internal bezel. This keeps the watch safe from being accidently knocked out of position and leading to miscalculated dive times.
To help make the present watch the period piece that it is, as well as a much sought-after collectors piece, are the original fish logo crowns, the case back with embossed submarine surfacing, the EPSA logo inside the case back and the lack of IWC logo on the dial meaning it is an early example.
