Best Dive Watches Under $500 (2026): 4 Real Divers We Recommend

Updated October 2026 · By the Montre24 editorial team

Short answer: the best dive watch under $500 for most people is the Orient Kamasu ($375): an automatic movement, sapphire crystal, 200 m water resistance and a screw-down crown. If you want a quartz watch you never need to wind, choose the Citizen Promaster Diver Eco-Drive, which Citizen describes as ISO-certified and powers with light. The Bulova Marine Star Series B is the alternative automatic with a sapphire crystal, and the Timex Deepwater Reef 200 is the most affordable of our picks.

Plenty of watches look like divers. Fewer have the specifications that matter in the water. For this guide we only included watches with at least 200 m water resistance, a screw-down crown, a unidirectional rotating bezel, luminous hands and markers, and an official US price of $500 or less. Several popular models failed one of these tests; we explain which ones and why at the end.

Prices were checked on the official US brand websites in October 2026 and may change. Where a brand store showed a sale price, we list it first and the regular price in brackets. Retailers often sell for less.

Comparison at a glance

The best dive watches under $500, reviewed

1. Orient Kamasu — best overall ($375, regularly $580)

The Kamasu combines the features that matter most in an affordable diver: 200 m water resistance, a screw-down crown, a 120-click unidirectional steel bezel and a sapphire crystal, which is still uncommon at this price. Inside is Orient's in-house F6922 automatic movement with hand-winding, hacking and about 40 hours of power reserve.

The 41.8 mm case is 12.8 mm thick with a lug-to-lug length of about 47 mm, so it wears comfortably on most wrists. Orient's regular US price is $580, but the brand store has been selling it at $375, and Orient backs it with a three-year warranty.

• Pros: sapphire crystal, in-house automatic movement, 200 m, three-year warranty
• Cons: no ISO certification claimed by Orient, best value depends on the current sale price
• Buy it if: you want one mechanical dive watch that covers swimming, snorkelling and everyday wear

2. Citizen Promaster Diver Eco-Drive BN0150 — best solar ($360, regularly $450)

This is the only watch on our list that its manufacturer describes as ISO-certified: Citizen calls the BN0150 an “ISO-compliant Promaster Professional Diver”. It runs on Citizen's Eco-Drive system, which converts light into energy and does not require the routine battery replacements associated with conventional quartz watches.

The 44 mm case is the largest here, and the crystal is mineral rather than sapphire. In return you get a proven diving tool with a one-way rotating bezel, luminous hands and markers, and Citizen's five-year warranty, the longest on this list. The blue BN0151-09L version has the same specifications.

• Pros: ISO-certified according to Citizen, solar-powered, five-year warranty
• Cons: mineral crystal, 44 mm may feel large on smaller wrists
• Buy it if: you actually dive and want a watch that keeps running with minimal maintenance

3. Bulova Marine Star Series B 98B466 — best alternative automatic ($440, regularly $550)

Bulova's Marine Star Series B pairs a 41 mm steel case with an 8215 automatic movement and about 42 hours of power reserve. It has 200 m water resistance, a screw-down crown with crown guards, a one-way rotating bezel with a two-tone aluminium insert, and an anti-reflective sapphire crystal. An exhibition caseback shows the movement.

Bulova does not claim ISO 6425 certification for this model and lists its water resistance for swimming and snorkelling, so we describe it by its stated specifications rather than treating it as an ISO-certified diver. The blue gradient dial on a steel bracelet makes it one of the dressier options here, and it comes with a three-year warranty.

• Pros: sapphire crystal, compact 41 mm case, exhibition caseback
• Cons: no ISO claim, regular price above $500, best value depends on the current sale price
• Buy it if: you want an automatic diver that also looks smart with a shirt

4. Timex Deepwater Reef 200 TW2W95200 — best value ($269)

The Deepwater Reef 200 shows how much dive watch $269 can buy. Timex fits it with 200 m water resistance, a screw-down crown and screw-on caseback, a unidirectional bezel, Super-LumiNova on the hands and indices, and an anti-reflective sapphire crystal, all in a 41 × 12 mm stainless steel case on a bracelet.

It uses a quartz movement, so it is more accurate than any automatic here and needs only an occasional battery change. The main compromise is support: Timex offers a one-year warranty, the shortest on this list.

• Pros: sapphire crystal and screw-down crown at the lowest price here, accurate quartz movement
• Cons: one-year warranty, no ISO claim
• Buy it if: you want a well-equipped 200 m watch for swimming and holidays without spending much

What just missed the cut

These watches have strong dive specifications but did not meet our price rule at the time of checking:

• Tissot Seastar 1000 Quartz 40 mm – an excellent 300 m Swiss diver with a sapphire crystal, but its official US price of $515 puts it just outside our $500 limit.
• Seiko Prospex “Turtle” SRPE93 – a classic Seiko diver with 200 m water resistance and the 4R36 automatic, listed at $525 on Seiko's US site.
• Citizen Promaster Dive Automatic – Citizen's automatic “Fugu” divers currently start at $575 in the US.

On a very tight budget, the Casio Duro MDV-106 deserves a mention: Casio lists 200 m water resistance, a screw-lock crown and a rotating bezel, and major US retailers usually sell it for well under $100. Casio's US site did not show a price when we checked, so we have not ranked it.

Why the Seiko 5 Sports SRPD55 isn't on this list

The SRPD55 is our favourite first automatic in our guide to the best automatic watches under $500, and it looks like a classic diver. But it is rated to 100 m and does not have a screw-down crown, so it does not meet our criteria for a dive watch. It is fine for swimming; for diving, choose one of the watches above.

How to choose a dive watch under $500

1. Water resistance. The rating is a laboratory test pressure, not a safe diving depth. For this guide we use 200 m water resistance and a screw-down crown as our minimum criteria, but the depth rating alone does not establish that a watch is certified for diving. Always follow the manufacturer's guidance for the specific model.
2. ISO 6425. This international standard for divers' watches covers much more than depth: it includes a unidirectional bezel, legibility in the dark, and tests for shocks, magnetism and condensation. Only trust an ISO claim when the manufacturer makes it; a 200 m rating alone does not make a watch ISO-certified.
3. Automatic, quartz or solar. Automatics are traditional and do not need a battery, but they gain or lose a few seconds a day and stop if left unworn. Quartz is more accurate; solar quartz like Citizen's Eco-Drive also removes routine battery replacements.
4. Crystal. Sapphire (Kamasu, Bulova, Timex) resists scratches far better than mineral glass. Mineral glass is cheaper and less likely to shatter but marks more easily.
5. Size and strap. Divers tend to be large. Check the diameter and thickness against your wrist, and remember that a rubber strap is more practical in water than a leather one.

FAQ

Can I scuba dive with a 200 m watch?

Many 200 m watches are designed for substantial water exposure, but suitability for scuba diving depends on the model and the manufacturer's guidance. ISO 6425 certification provides a clearer indication that a watch has been tested as a diver's watch. In any case, keep the crown fully screwed in whenever the watch is in water.

Do I need an ISO 6425 certified dive watch?

For swimming and snorkelling, no. For regular scuba diving, an ISO-certified watch such as the Citizen Promaster Diver gives extra assurance, because the standard tests much more than water resistance. Most divers also use a dive computer as their primary instrument.

Automatic or quartz for a dive watch?

Both work. Quartz and solar watches are generally more accurate and require less day-to-day attention. Automatics appeal to people who enjoy mechanical watchmaking and want a watch that does not rely on conventional battery replacements.

How often should a dive watch be pressure-tested?

If you swim or dive regularly, follow the manufacturer's recommendations for water-resistance checks, and have the seals tested after the case has been opened, for example for a battery change, or whenever there is reason to doubt its water resistance.
