Edox Watch Hydro-Sub Chronometer 80128 357JNM VID. The Edox Hydro-Sub was first presented in 1965 and was already water-resistant to at least 300 metres. At that time, the Swiss watch brand was considered the “Water Champion” of the watch industry. Both technically and aesthetically, the new Edox Hydro-Sub reflects the timelessly cool look of an Edox diving watch from the 1960s. The most important details of the original have been retained and perfected.
