11 Factors to Consider When Choosing Your First Dive Watch

Published on
dive watches

If you’re planning on exploring the depths of the ocean and need a reliable timepiece to accompany you, a dive watch is an essential piece of gear to consider. 

With so many options available, picking the right one for your needs can be a daunting task. To help make the process easier, we’ve compiled a list of 11 crucial factors to consider when selecting your first dive watch. 

From water resistance and durability to features like bezels and luminescence, these factors will help you find a watch that can withstand the rigors of underwater exploration and keep you on track during your dives. 

So, whether you’re a seasoned diver or just starting out, read on to learn more about what to look for in your first dive watch.

11 Important Features to Keep in Mind

By keeping these factors in mind, you’ll be well-equipped to choose a watch that meets your needs and provides a safe and enjoyable diving experience.

1. Water Resistance – At least 200 m

When you’re investing in a dive watch, water resistance is your first priority. When it comes to the best dive watches and their water-resistance ratings, it can get complicated quickly. You should check the International Organization for Standardization (ISO) rating for the particular timepiece you’re eyeing.

The higher the number, the more suitable it is for more serious diving. ISO standards for dive watches are 200m and 300m; anything above that number is considered overspec and unnecessary for recreational diving purposes.

2. Crown – Screw-Down

Another important characteristic of dive watches is the construction of the watch crown. Unlike regular watches, dive watches typically feature screwable crowns instead of push-pull crowns. The screwable crown provides a more watertight and pressure-resistant seal, ensuring that the watch is protected against water damage.

Compared to push-pull crowns, screwable crowns are much less likely to accidentally pop open, which is a critical consideration during a dive. In addition to the screwable crown, most dive watches also feature a screw-down caseback, which provides a more watertight seal than other types of casebacks, such as screw-on and snap-on casebacks.

Overall, the screwable crown and screw-down caseback are essential features of a dive watch that ensure the watch can withstand the harsh conditions of underwater environments and maintain its accuracy and reliability over time.

3. Bezel – Unidirectional Bezel with Minute Markers

The bezel, or the ring around the outside of the watch face, serves only a matter couple of different purposes. On a dive watch, like other sports watches, the rotating bezel is often used as a “countdown timer,” as it’s usually calibrated with markers representing minutes. So by turning it to align with the minute hand when you jump in with your scuba gear, you can track how much time you have underwater.

Additionally, some dive watches will have a unidirectional bezel—meaning it will only turn counterclockwise—to prevent accidentally under-calculating your dive time if you bump into something or otherwise jar it while diving. Pay close attention to how this internal bezel works during your research of other dive watches and make sure to understand the unique way each brand’s bezels operate before deciding on a purchase.

4. Dial and Hands – Luminous That Can Be Read Underwater

The dial of your dive watch should be easy to read, even in low-light conditions. Look for a dial that is marked clearly and is made from quality materials. These materials include a luminous sapphire crystal, ceramic, or steel. The sapphire crystal has greatly increased visibility in dim or dark conditions and is known for its scratch resistance.

The important hands of a dive watch—minute hand, hour hand, chronograph second hand—should be large and legible so you don’t have to squint to read the time underwater. The hands should be easily separated from each other at a glance, as well as from all the watches markings on the dial. Make sure they are made from durable materials such as steel or titanium so they remain legible and do not rust with exposure to water.

5. Material – Stainless Steel, Titanium, or Ceramic

Material is an important factor to consider when buying a dive watch. You want something that is tough and resistant to water and other elements. The most common materials are stainless steel, titanium, and ceramic due to their durability.

Stainless steel is resistant to corrosion, making it the most popular choice. It’s also relatively affordable and comes in different styles such as gold or silver.

Titanium watches are lightweight, durable, and corrosion-resistant. Titanium watch is also hypoallergenic if you have sensitive skin. However, they can be fairly pricey compared to steel models.

Ceramic watches are highly scratch-resistant which makes them perfect for underwater activities. They also offer a sleek aesthetic which can make them a fashionable statement piece as well as a functional watch. However, they tend to be more expensive than other options on the market.

6. Movement – Automatic, Mechanical or Quartz 

The type of movement in a watch can greatly affect its performance, and this is especially important when it comes to dive watches. Automatic, mechanical, and quartz movements are the three most common types of movements found in watches, each with their own unique advantages.

  • Automatic movements are self-winding and rely on the movement of the wearer’s wrist to keep the watch powered. They are often preferred for their convenience and require minimal maintenance.
  • Mechanical movements, on the other hand, are powered by a wound spring and are highly regarded for their craftsmanship and precision. They require regular winding and maintenance to keep them running accurately.
  • Quartz movements are battery-powered and offer exceptional accuracy and reliability. They are often used in digital watches and are highly valued for their low-maintenance nature.

7. Strap (Matters a lot!) – Look for Steel or Rubber Bracelets

No true dive watch is complete without a reliable, sturdy strap. The two main types of straps are metal bracelets and rubber or synthetic straps.

Metal bracelets are generally more expensive than other strap types, but they offer superior strength and durability. They warranty a long-lasting product that can withstand even the most challenging dives thanks to their strong construction. Plus, they look great with casual outfits as well as formal attire.

Rubber straps are mild on the skin, resistant to moisture and come in various colors and designs. They’re cheaper than metal bracelets, though they lack the strength of metal ones. Fortunately, there are many synthetic material options available that combine the best of both worlds: affordability with durability and style.

8. Size and Weight – Look for Lightweight; 100-200 grams

When shopping for a dive watch, it’s important to consider the size and weight of the model you’re looking at. Not only should the watch fit comfortably on your wrist, but it should also be lightweight enough to allow you to perform tasks underwater with ease. The ideal weight for a dive watch is around 100-200 grams.

Most dive watches come in different weights—from lightweight polymers to heavy steel cases—and you’ll want to make sure you pick something that won’t drag you down while swimming or diving. Check out various models and feel the weight difference, as this can make all the difference during a dive.

9. Helium Release Valve – Optional

Dive watches may feature a helium release valve as an optional component. This valve is typically located on the opposite side of the crown and is designed to release helium molecules that can accumulate inside the watch case during saturation diving.

Helium release valves are essential for commercial saturation divers and military divers who spend prolonged periods at great depths in diving bells or submersibles. During these dives, the helium gas can penetrate the watch case and build up pressure as the divers return to the surface. If the pressure is not released, it can cause the watch crystal to pop off or damage the movement.

By releasing the excess gas through the helium release valve, the watch case’s pressure can be regulated without compromising its water resistance. 

It is worth noting, however, that a helium release valve is not necessary for recreational scuba diving, as helium gas does not usually penetrate the watch case during normal diving activities. This feature is typically found on high-end professional dive watches and is designed for use in extreme deep-sea conditions.

10. Brand Reputation – Look for Reviews

It’s important to do your research and ensure that you’re investing in a reliable and respected brand. Some features to look out for include:

  • Longevity: Look for a brand with a long history of producing quality dive watches.
  • Innovation: A brand that continually innovates and improves their watches is more likely to produce reliable and high-quality timepieces.
  • Professional partnerships: Check to see if the brand has partnerships with professional divers or organizations, as this can be a sign of their commitment to producing high-quality dive watches.
  • Customer reviews: Read customer reviews and feedback to get an idea of the brand’s reputation and the quality of their products.
  • Service and support: A reputable brand should offer excellent customer service and support, including warranties and repair services.

11. Price – Depends on Your Budget

You can get all the features you need for recreational diving at an affordable price, starting at S$200. Of course, if you’re looking for a more professional model or divers watch with specialized features like multiple time zones or helium valves, then you should expect to pay more, up to hundreds of thousands. 

The bottom line is that it’s important to find a dive watch that fits your budget without sacrificing quality or safety.
