Dive watches are tools underwater. They have functionalities that allow divers to measure time while submerged in the water. A diving watch is different from the other watches, in terms of its features and materials used. Given the differences, there are essential points to remember when it comes to choosing the right diving watch for you.
The Parts of a Dive Watch
- Luminous Dial, Indices, and Hands – Having luminous dial, hands, and indices are essential in a diving watch. It aids in better visibility underwater.
- Durable Straps – Due to pressure and water movement, the watch should have robust straps to withstand the underwater environment.
- Rotating Bezel – Diving watches have bezels to help divers track the elapsed time while submerged in the water.
- Sturdy Case – The case is the protection of the watch, which prevents water from damaging the watch. The case must be made of quality materials.
- Movement – The mechanism is also essential since it is the powerhouse of the watch.
Just like the pilot and other types of watches, a diving watch is an exceptional tool with combined functionality and aesthetics.
Common Dive Watch Terminologies
- Water Resistance – refers to a watch’s ability to withstand pressure
- Atmospheres – often abbreviated ATM, a unit of pressure
- Bar(s) – a metric unit of pressure
- Meters – the measurement of how deep the watch can be submerged underwater
- ISO Certification – refers to the International Organization for Standardization. For diving watches, it is ISO 6425
- Lume – allows the watch to glow in the dark
- NATO – a type of watch strap that is named after the British Ministry of Defence. It is perfect for rugged conditions
- Quartz Movement – a watch that uses a battery to power the watch
- Automatic Movement – any timepiece that has a rotor and mainspring that harness energy from the wearer’s natural movements
Buying Guide Tips
Are you planning to buy a dive watch soon? Here are some tips to follow.
It is necessary to understand the concept of water resistance in diving watches. Again, the common points to note are the following:
- Below 10ATM –suitable for showering
- 10 ATM – for swimming
- 20 ATM – suited for snorkeling
- 300 meters – light scuba diving
- Above 300 meters with ISO 6425 certification – scuba diving watches
Another thing is the luminous on the dial’s indices and hands. Almost 99% of diving watches have luminous on its time-indicating parts as well as the bezel. The luminous may come in the form of radium-based, tritium, or photoluminescent. Make sure to check this when choosing a tool watch.
For the bezel, choose one that is made of ceramic with 120 positions instead of the standard 60. On the other hand, the dial with sapphire glass is the best choice.
Steps to Consider in Choosing a Tool Watch
- What is the purpose of the watch?
Understand the use of the watch. Is it for diving, swimming, or just for fashion?
- Determine the water resistance needed.
We recommend you check the water-resistance rating on the watch before wearing.
- Check the movement.
Based on your preference and budget, decide whether to choose quartz or an automatic movement.
- Choose the strap.
Get a strap that is comfortable for you. The recommended ones are NATO, rubber, and stainless steel bracelets.
