In the middle of the 20th century, as mankind turned its eyes skyward in a quest to conquer the stars, so too did it turn its gaze toward the water that covers 71 per cent of the earth’s surface. As diving became more widespread, both commercially and as a leisure activity, watchmakers had to meet the demand for watches that could remain water resistant to ever increasing depths.
The standards for what exactly constitutes a divers watch is regulated and defined by ISO-6425 – this is the international standard for divers watches. Only watches that are officially, formally and technically ISO-6425 certified, are considered to be full-fledged divers watches. In order for a watch to be qualified to be called a divers watch, the watch needs to be water resistant down to 330 feet/100 meters minimum.
A divers watch must also feature a time controller – usually a unidirectional bezel with which you can measure for how many minutes you’ve been under water. The indexes of the dial must be luminescent in the dark, and the timepiece must have a solid band, anti-magnetic properties and shock resistance.
