Hey there, fellow dive enthusiasts! Whether you’re a seasoned pro or just dipping your toes into the world of scuba, you’ve probably noticed those chunky, rugged watches adorning the wrists of divers. But in an age of high-tech dive computers, you might be wondering: what’s the deal with dive watches? Are they still relevant, or just a nod to diving’s past? Let’s dive in and explore the role of these iconic timepieces in modern scuba diving.

What is a Dive Watch?

First things first: what sets a dive watch apart from that sleek smartwatch you wear to the office? Dive watches are purpose-built for underwater use, featuring water resistance typically to at least 200 meters, luminous hands and markers for readability in low light, and a unidirectional rotating bezel to track dive time. They’re built tough to withstand the pressures of the deep and the corrosive effects of saltwater.

A Brief Plunge into History

Dive watches made their splash in the 1950s when scuba diving began gaining popularity. Back then, they were essential tools for staying alive underwater. Early models like the Rolex Submariner and Blancpain Fifty Fathoms became the blueprint for the dive watches we know today. As diving tech evolved, so did these watches, incorporating features like helium escape valves for saturation diving.

Essential Functions: More Than Just Telling Time

So, what can a dive watch do for you underwater? Let’s break it down:

1. Timekeeping: Sounds basic, but knowing how long you’ve been underwater is crucial for managing air supply and decompression limits.

2. Dive time tracking: That rotating bezel isn’t just for show. Align the zero marker with the minute hand at the start of your dive, and you can easily read your elapsed time.

3. Depth measurement: Some advanced dive watches include depth sensors, though this isn’t a standard feature.

4. Decompression tracking: While not as sophisticated as dive computers, some watches have basic decompression tables printed on the strap or dial.

Dive Watches vs. Dive Computers: The Showdown

Now, let’s address the elephant in the room – or should I say, the computer on the wrist. Dive computers have largely replaced watches as the primary underwater timing and depth-tracking device. They provide real-time data on depth, time, decompression status, and even air consumption when integrated with your tank.

So why bother with a dive watch? Here’s the scoop:

1. Simplicity and reliability: Dive watches are less likely to glitch or run out of battery mid-dive.

2. Backup: Many divers use a watch as a backup to their computer.

3. Surface interval timing: Great for keeping track of time between dives.

4. No learning curve: Easy to use without scrolling through menus or understanding complex algorithms.

That said, for technical diving or pushing recreational limits, a dive computer is pretty much essential. Many divers opt to use both for redundancy and the best of both worlds.

Practical Uses in Modern Scuba Diving

Despite the rise of dive computers, watches still play several roles in modern diving:

1. Primary timer for simple dives: For shallow, short recreational dives, a watch can be sufficient.

2. Backup device: If your computer fails, a watch can help you safely end your dive.

3. Surface interval tracking: Easy way to time your surface breaks between dives.

4. Decompression stop timing: Simple and effective for timing safety stops.

Choosing the Right Dive Watch

If you’re in the market for a dive watch, here’s what to look for:

1. Water resistance: At least 200m for recreational diving.

2. Luminosity: You need to read it in the murky depths.

3. Rotating bezel: Unidirectional to prevent accidental increases in dive time.

4. Strap: Needs to fit over your wetsuit or drysuit.

As for movement, mechanical watches offer classic appeal and don’t need batteries, but quartz watches are often more accurate and affordable. Your budget will play a big role – quality dive watches in 2024 range from under $100 to well over $10,000 for luxury models.

Beyond the Depths: The Appeal of Dive Watches

Let’s face it – part of the allure of dive watches is how cool they look. They’ve become style icons, worn by everyone from actual divers to cubicle dwellers who never get closer to the ocean than their local pool. They’re tough enough for everyday wear, look great with a suit or shorts, and carry a bit of adventure on your wrist.

For some, dive watches are serious collectibles. Vintage models can fetch eye-watering prices, and even modern limited editions become instant classics.

The Bottom Line

So, are dive watches essential for modern scuba diving? For most recreational divers, probably not. A dive computer is a more versatile and informative tool. But dive watches still have their place – as reliable backups, simple timing devices, and yes, as stylish connections to diving’s rich history.

Whether you choose to dive with a watch, a computer, or both, the most important thing is to dive safely and enjoy the underwater world. After all, that’s what it’s all about!


Q: Do I really need a dive watch if I have a dive computer?

A: Not necessarily, but many divers appreciate having a simple, reliable backup.

Q: How deep can dive watches really go?

A: Most dive watches are rated to at least 200m, with some professional models going much deeper. However, the practical limit is usually the diver, not the watch!

Q: How long can a dive watch typically last with proper care? 

A: With proper care and regular servicing, a quality dive watch can last for decades. Many mechanical dive watches are built to be heirloom pieces, potentially lasting a lifetime or more. Quartz dive watches might need battery replacements every few years, but the watch itself can still function for many years. The key is proper maintenance – regular services, careful use, and prompt attention to any issues.

Q: Are expensive dive watches worth it for recreational divers?

A: In terms of functionality, probably not. But if you appreciate the craftsmanship and history, a high-end dive watch can be a treasured possession.

Q: Can I wear my dive watch all the time?

A: Absolutely! Dive watches are built tough and designed for everyday wear.

Q: How often should I service my dive watch?

A: For mechanical watches, every 2-3 years is a good rule of thumb. Quartz watches need less frequent servicing, but battery changes should be done by a professional to ensure water resistance isn’t compromised.
