This is the Steeldive SD1964 which is a homage to the Sea-Dweller which was developed in late 1967 to counteract the problems caused by decompression when Helium atoms inside a pressure chamber can work their way inside a watch. During decompression, the pressure inside the chamber can decrease more rapidly than the pressure inside the watch case. This can, in some cases, cause the watch crystal to pop off. The helium-release valve allows helium to escape from the case during decompression preventing damage to the watch.Although resembling the Submariner, it is a bigger watch and has more presence on the wrist.
