Whether diving into the depths of the deep, blue seas or the ever-changing fashion world, these watches will equip you for the inevitable.

Diver watches came about to fulfill a specific reason. It is meant to provide accurate, illuminated time with a mechanism to measure the depth of the seas with a rotating bezel. It also has to be resilient enough to withstand being submerged into great aquatic depths.

A true diver watch is in accordance with the standardisation of the International Organisation for Standardisation (ISO), with a long list of requirements to adhere to for the distinction of a diving watch.

In a nutshell, it needs a few of these essential features – water resistance to a minimum of 100 meters, particular levels of visibility and legibility in total darkness, magnetic, shock, and chemical resistance, and an illuminated second hand that indicates that the watch is working, even in complete darkness.

These days, a diving watch is just as much of a fashion statement as it is a piece of sophisticated underwater equipment. So, whether you are diving into the great deep blue or the worldly fashion world, these are the six latest ones to keep an eye out for.
