Best Affordable Dive Watches

The dive watch is probably the most versatile watch style there is. It was built for scuba divers, yet the same features (a rotating bezel, bright lume, a sealed case) are just as useful for timing a parking meter, swimming laps or getting caught in the rain. Most dive watches today never go near a reef, and that’s fine.

What separates a genuine dive watch from one that only looks the part is in the details: the water resistance rating, the type of bezel, the crown and the lume. Below, we explain what to look for and recommend five divers, from a budget quartz model to a Swiss step-up, along with one popular dive-styled watch that falls short of the full spec.

Our picks for the best affordable dive watches

Casio Duro MDV106

The Duro proves you don’t need to spend much to get the core dive watch features. The published specs list a stainless steel case with an aluminum bezel insert, a unidirectional bezel, a screw-lock crown and case back, luminous hands and markers, and 200 m of water resistance. The quartz movement is quoted at ±20 seconds a month.

The MDV106 is discontinued and being replaced by the MDV-107, so it may become harder to find; the newer model is the one to look for. At 44.2 mm wide and 48.5 mm lug-to-lug, it’s also a big watch. For more budget options, see our watches under $100 guide.

Citizen Promaster Diver BN0150

For a dive watch that is always ready, the Promaster’s Eco-Drive is hard to beat. It charges from any light, and Citizen quotes approximately six months of running from a full charge. The 200 m rating is described as an ISO-style scuba rating, and you get a unidirectional elapsed-time bezel and luminous hands and markers.

The 44 mm case is wide but just 11.54 mm thick. It comes on a polyurethane strap, which is a sensible choice for water use.

Orient Kamasu

The Kamasu gives you a mechanical movement and a sapphire crystal in a 200 m diver, a combination that’s uncommon in its price band. Orient specifies a 41.8 mm steel case, a unidirectional dive bezel, a screw-down case back and the in-house F6922 with hacking, hand-winding and day/date.

The 46.5 mm lug-to-lug makes it the most moderately sized diver here. If you want an automatic dive watch without going big, start with this one.

Seiko Prospex ‘Turtle’ SRPE93

The Turtle’s cushion case is one of Seiko’s best-known dive watch shapes. The SRPE93 has a 45 mm steel case 13.4 mm thick, a unidirectional bezel, a screw-down crown, a screw case back and 200 m of water resistance, with the 4R36 automatic inside.

Despite the 45 mm width, the lug-to-lug is a fairly compact 47.7 mm. It still needs a medium-to-large wrist. Check our watch size comparison tool against a watch you already own.

Longines HydroConquest 41mm

If you want one dive watch to keep for years, the HydroConquest is a big step up. Longines lists 300 m of water resistance, a scratch-resistant ceramic bezel insert, sapphire with anti-reflective coating on both sides, a screw-in crown, a screw-down case back and Super-LumiNova. The L888 movement offers up to 72 hours of reserve.

It’s typically sold above $1,000, so it’s outside the budget of the other picks. The 51.1 mm lug-to-lug is long for a 41 mm case, so measure your wrist first.

Dive-styled but not a full diver: Seiko 5 Sports SRPD55

The Seiko 5 Sports SRPD55 looks like a dive watch, with a unidirectional bezel and LumiBrite lume, but it’s rated to 100 m rather than 200 m. That’s plenty for swimming and snorkeling, so treat it as a dive-styled everyday watch. See our Seiko 5 Sports review for the details.

What makes a real dive watch

ISO 6425

ISO 6425 is the international standard for divers’ watches. Among other things, it requires a minimum of 100 m water resistance, a way of presetting elapsed time (usually a unidirectional bezel), legibility in darkness at 25 cm, a running indicator visible in the dark, and testing for shock, magnetism and resistance to salt water. Watches that are certified to it are typically marked “DIVER’S” on the dial. Many affordable divers are built along similar lines without formal certification, which is perfectly adequate for recreational use.

Unidirectional bezels

A dive bezel turns only counter-clockwise. You align the zero marker with the minute hand at the start of a dive; if the bezel is knocked, it can only show more elapsed time, never less, which errs on the safe side. Aluminum inserts are cheap and easy to replace but can scratch and fade; ceramic, as on the HydroConquest, is far more scratch-resistant.

Lume

Luminous material on the hands and markers is what makes a dive watch readable underwater and in the dark. Common types include Super-LumiNova and Seiko’s LumiBrite. Brightness and duration vary by application and the amount used, so this is one area where specs alone tell you little.

Screw-down crowns

The crown is the most common entry point for water. A screw-down (or screw-lock) crown threads onto the case tube and compresses a gasket, sealing it far more securely. The Duro, Turtle and HydroConquest all list one. Always check it’s screwed down before swimming.

Choosing the right affordable diver for you

Quartz, solar or automatic?

All three movement types work well in a dive watch, and each suits a different owner. Quartz, as in the Duro, is accurate and cheap to run, but the battery will need changing every few years, and every time the case back comes off the seals should be checked. Solar quartz, as in the Citizen Promaster, removes routine battery changes and keeps quartz accuracy, which makes it a strong choice for a watch that lives in a travel bag. Automatics like the Kamasu, Turtle and HydroConquest appeal to people who enjoy mechanical watches, but they drift more than quartz and stop when left off the wrist past their power reserve. If you’re undecided, our automatic vs quartz guide sets out the trade-offs.

Crystal choice matters more on a diver

Dive watches tend to get knocked against ladders, rocks and boat rails, so the crystal takes more abuse than on a dress watch. Sapphire, at around 9 on the Mohs scale, is far more scratch-resistant than mineral glass. Among these picks, the Kamasu and HydroConquest use sapphire, while the Duro and Promaster use mineral and the Turtle uses Seiko’s Hardlex. None of those is fragile, but expect scuffs to accumulate faster on the non-sapphire models.

Straps and bracelets in the water

Rubber, silicone and polyurethane straps are the practical choice for swimming because they dry quickly and don’t absorb salt or chlorine. Leather is a poor match for regular water use. Steel bracelets, like those on the Kamasu and HydroConquest, are durable and dressier, but benefit from a rinse to clear grit from the links. A 20 mm or 22 mm lug width, which covers most picks here, gives you the widest choice of replacement straps.

Size and wearability

Dive watches run large. Four of the five picks here are 41.8 mm or bigger, and three are 44 mm or more. Diameter is only part of the story, though. The 45 mm Turtle has a shorter lug-to-lug (47.7 mm) than the 41 mm HydroConquest (51.1 mm), and lug-to-lug is often what decides whether a watch overhangs your wrist. Our wrist measuring guide shows how to check before you buy.

How we chose

We didn’t wear these watches or test them in the water. This is a research guide: we compared manufacturer specifications against published sources, prioritized dive-relevant features (water rating, bezel type, crown, lume), and weighed track record and value within each price band. Our methodology page explains our approach.

Frequently asked questions

The bottom line

For a budget diver, the Casio Duro still delivers while stock lasts. The Citizen Promaster is the low-maintenance choice, the Orient Kamasu offers sapphire and an automatic movement for modest money, and the Seiko Turtle brings heritage for larger wrists. If you want to buy once, the Longines HydroConquest is the step up. For more watches in the mid-range, see our watches under $500 guide.
