What is a diver's watch?
Diver's watches are called "submersible watches" among the water resistant watches specified by the JIS standard. As the name implies, they are special watches that can be used for diving.
Among them, it is divided into a pro-spec model that can support saturated diving and a model for general users who can scuba diving.
This is a watch that not only has excellent water resistance but also has passed various strict standards of ISO and JIS.

Divers watch definition
The definition of a diver's watch is that it has a pressure resistance (equivalent to 125 m for 100 m) that can withstand at least 100 m diving and 1.25 times the water pressure, and that it has a function to manage diving time.
Since it is assumed that it can function normally in the deep sea and can be used safely and accurately, it has passed various tests such as visibility, magnetic resistance, impact resistance, salt water resistance, external force, water tightness, helium gas resistance etc. Must do it.
Even if it is written as 100m waterproof, it cannot be said to be a diver's watch unless these standards are met.

Diving watches, which have a variety of excellent features, are often chosen for everyday use, and each brand is developing models that emphasize design and practicality, making them even more popular.
Here, we will introduce the main functions and features of the diver's watch.
Here, we will introduce the main functions and features of the diver's watch.
1. Waterproof and durable
The best feature of a diver watch is, of course, waterproof performance.
Most models called diver's watches have a waterproof performance of 200m or more.
The popular Rolex Submariner is waterproof to 300m, but there are also models with greater depths, such as 1000m and 2000m.
Hublot's Oceanographic model is also water resistant to 4000m.
In addition, the bracelet and rotating bezel are hard to break because it often hits the rock surface or the hull, making it a durable and robust construction that can be used safely even in harsh deep sea environments.

2. Visibility
Divers must work in deep water, where the sun's rays do not reach.
Divers' watches are required to be able to see the time and the operating status of the watch in a dark place from a distance of 25 cm.
Luminous paint is applied to indexes, hands, and bezels to enhance visibility, and it is characteristic of glowing in the dark.
At 12 o'clock on the rotating bezel, luminous paint called Luminous Point is attached, but the bezel of a popular model seems to have many such designs.

3. Unidirectional rotating bezel
Diver's watch also defines the item "has a function to manage diving time."
Most models use this rotating bezel to measure the dive time (= cylinder remaining air time, decompression time).
Some have an inner bezel, such as the IWC Aquatimer.
The reason that the bezel is designed to rotate only in the reverse direction is to prevent the bezel from rotating and reading the elapsed dive time short when hitting.

4. Helium escape valve
The helium escape valve is a mechanism that allows helium that has entered the watch to escape outside the watch.
Helium gas is used by professional divers for diving.
Helium is a very small molecule, so it can easily find its way into a watch through gaps when working at depth or in a decompression chamber.
The helium escape valve is responsible for releasing the helium that has entered the tank. If helium accumulates inside the watch, it will burst, so you need to slowly release it as you ascend.

5. Extension buckle
It is a feature that is rarely seen except for divers watches, but some metal bracelet models allow you to freely adjust the length of the bracelet.
Although it is about 30mm even if it is free, it is a function provided so that you can wear a diver's watch from above the diving suit.

Recommended popular ROLEX models
Representative of divers watch. The most famous and always popular model is the Rolex Submarina.
Appeared in the 1950s, variations in "date availability" and highly waterproof "Sea-Dweller" and "Deep Sea" in top models are as popular as they are.
There's a wide range of prices and variety, but even though they're "in stock," they sell out quickly. This is a model you won't want to miss.
