Buying a Dive Watch? Learn the Essential Features to Look For
In this guide, we’ll break down the essential features you should look for in a professional-grade dive watch, focusing on quality, durability, and functionality. Let’s dive in.
1. Automatic Mechanical Movement
When it comes to true dive watches, automatic mechanical movements are highly sought after. Unlike quartz movements, automatic watches are powered by the natural motion of your wrist—no batteries needed. This not only provides a smoother sweep of the second hand but also appeals to watch purists who value craftsmanship and tradition.
Why it matters:
An automatic movement is reliable in extreme conditions, doesn’t rely on electronics, and adds mechanical artistry to your dive experience.
2. 100m Water Resistance (or More)
At an absolute minimum, a dive watch should be rated to 100 meters (330 feet) of water resistance. This depth rating ensures the watch can withstand the pressure of recreational diving and provides peace of mind for anyone spending time in or around the water.
What depth are DIVE timepieces rated to?
All of the case set key components are designed, built and tested to 200m /660ft
3. Screw-Down Crown
One of the most critical components of a dive watch is the screw-down crown. This feature ensures a watertight seal by screwing securely into the case, helping to prevent water from entering the watch—even at great depths.
Why it’s essential:
A push-pull crown can accidentally pop open under pressure. A screw-down crown minimizes the risk of water damage during a dive.
4. Screw-Down Case Back
To further reinforce water resistance, a dive watch should also feature a screw-down case back. This design locks in the movement and seals the rear of the watch case, preventing water ingress through the backplate.
Added bonus:
A DIVE screw-down case back includes engraved artwork, specifications and unique Limited Edition Serial Number, giving your timepiece character and uniqueness.
5. Double Domed Sapphire Crystal
Sapphire crystal is one of the most durable watch materials available, offering excellent scratch resistance and clarity. A double domed sapphire crystal reduces distortion when viewing the watch underwater or at an angle, providing superior legibility in any condition.
Why divers love it:
It looks great, performs even better, and stands up to the rugged underwater environment without compromising visibility.
6. Unidirectional Rotating Bezel
A unidirectional bezel is a must-have for dive watches. It lets you track elapsed dive time safely. Since the bezel only rotates counter-clockwise, if it’s accidentally bumped, it will shorten the remaining dive time—never lengthen it—protecting you from staying underwater too long.
How it works:
Align the zero marker with your minute hand before descending, and you’ll have a simple, reliable timer during your dive.
7. Lumed Bezel Insert and Markers
Visibility is crucial underwater, especially in low-light or murky conditions. That’s why high-quality dive watches include luminescent (lumed) bezel inserts and hour markers. These glow-in-the-dark elements ensure you can read the time and bezel at a glance, even in total darkness.
What to look for:
High-grade lume materials that offer bright, long-lasting illumination.
Final Thoughts: Choose Function Over Fashion (But Why Not Both?)
A real dive watch is more than just a rugged timepiece—it’s a piece of essential gear. While the looks are important, what’s under the surface matters even more. If you’re investing in a dive watch, prioritize these seven essential features to ensure you’re getting reliability, durability, and performance with every wear.
And the best part? With today’s craftsmanship and technology, you can get a dive watch that performs like a tool but looks like a luxury piece—ready for the ocean or the office.
