Are you a diver, a sea lover, or just envious when you saw someone with a fantastic sea dweller rubber strap and decided you had to buy a dive watch? Keep reading because you need a dive watch, and this article will help you a lot.
Suppose you practice the wonderful sport of diving. You will realize that there are a few kinds of plunging watches accessible; from simple basic models with just a single bezel (rotational) to consolidated advanced or simple models that additionally show profundity and jump time, to models that are more similar to a plunge PC for a wide range of information that can be seen and spared. This last type is also called a wrist dive computer. Well, these are great tools and technological aid, but they have certain disadvantages. The first and most obvious is that they are not a piece that displays your personality. The second point against them is that they can fail. Not your watch, especially if it is Swiss Made or certified as a Professional Dive Watch.
The standards and characteristics for diving watches are regulated by the International Organization for Standardization in the standard ISO 6425. It provides the minimum requirements for mechanical, quartz, and digital clocks. That is, the unidirectional rotating bezel. This graduation will allow the reading of the diving time according to the diver’s needs.
The waterproofing is generally indicated in the number of meters (fixed water column). Sometimes the waterproofing is shown in Bar or Atm(sphere), where 10 bar or 10 atm is equal to 100 meters of the fixed water column. The higher the number of meters (or bar/atm), the deeper you can dive with it. If it only says ‘waterproof,’ the watch is only splashproof!
How deep a dive watch is water-resistant depends on the model and price, but in general, dive watches are resistant to a depth of at least 100 meters (according to ISO 6425). That’s good for snorkeling and shallow dives. Today the criteria have been hardened, and although the barrier of 200 meters – 20 bar meets the international certification. The latest dive watches offer at least 300 meters guarantee. It should be noted that it is not whether the diver can reach this depth or not, as the pressure increases due to currents, temperatures, or other situations under the sea.
The indexes, hands, and numbers should be distinguishable on the watch face. You must comply with adequate visibility at 25 cm in total darkness. That is why the most advanced luminescence systems are used in this type of watch.
A classic analog diving watch is heavier than a regular watch. This is because the exterior and the bezel have to be made of material resistant to high pressure and seawater, saltwater. The most commonly used materials are stainless steel and titanium. There are also diving watches made of synthetic material. Often you will find a sea dweller rubber strap, polyurethane, or stainless steel. Please note that the belt is adjustable so that it can be placed on top of the wetsuit. The glass can be made of acrylic glass, mineral glass, or sapphire glass. Classic dive watches have a threaded crown that allows (out of the water) to set the time and date by “screwing the crown on top.”
