The dive watch is one of the most popular traditional watch styles among men. And it's easy to understand why. Beloved for their sturdy construction, pleasing heritage-inspired designs and inherent versatility, men's dive watches continue to endure as essential timepieces year after year, decade after decade. Scroll on for everything you need to know about dive watches, including our pick of the best men's dive watches to buy in 2024.
What is a dive watch?
To qualify as a dive watch, a watch must be able to withstand a minimum water-resistance of 10 atm (the equivalent of around 100 metres), but many dive watches can reach depths of 200-300 metres, and sometimes even more.
An important thing to note is that dive watches aren't actually tested in diving conditions. Rather, they are tested while stationary in a hyperbaric pressure chamber, so they don't account for any extra shifts of pressure that result from jumping into water or ascending from the depths of the sea. This is why an extra water resistance buffer exists – as you won't generally be descending any lower than 40 metres.
True contemporary diving watches are certified in accordance with the ISO 6425 professional dive watch standard. This means that – as well as withstanding a minimum depth of 100 metres – the dive watch should be equipped with a diving time indicator such as a rotating bezel or digital display, plus clearly distinguishable minute markings on the watch face. Other essential characteristics include adequate visibility at 25cm and magnetic, shock and chemical resistance.
Are dive watches waterproof?
Here's the thing: no watch is completely waterproof – even the most expensive luxury dive watches. This is why the International Organisation for Standardisation (ISO) prohibits the term "waterproof" and watches are only ever marketed as "water resistant". In saying this, well-constructed dive watches will certainly hold their own for activities like diving and recreational swimming. Just make sure not to wear yours in the bath, shower or spa, as excessive humidity can damage the watch.
How to wear a dive watch
The best men's dive watches are versatile in their looks, so can be worn in myriad contexts, with an array of wide-ranging ensembles. Don't let the name fool you: the wearing of a dive watch shouldn't be limited to the act of diving. In fact, the sporty yet sophisticated aesthetic of dive watches lends them effortlessly to everyday attire. Wear yours on the weekend with comfy drawstring trousers and leather trainers, or up the ante by teaming it with tailored trousers, a crisp tee and unstructured blazer for a fail-safe smart-casual look.
