Best Dive Watches
Under $500 in 2026

The Orient Kamasu delivers a spec sheet that seems impossible at $200: in-house automatic movement with hacking and hand-winding, sapphire crystal, 200m water resistance, and a solid stainless steel bracelet. The sunburst dial finishing is excellent across all colorways — green, blue, red, and black. The 120-click unidirectional bezel is smooth and precise.

The Kamasu is the dive watch that made every competitor raise their game. Sapphire crystal at $200 was unheard of before Orient forced the issue. The red dial variant is especially striking and unique at any price point.

The Seiko Turtle is legendary for its cushion-shaped case that sits incredibly comfortably on the wrist despite its 42.4mm size. The 4R36 movement provides hacking and hand-winding, and the 200m water resistance with a screw-down crown makes it a genuine dive tool. Seiko's LumiBrite indices are among the brightest in the industry — a real advantage in low-light conditions underwater.

The Turtle shape dates back to the 6309 from the 1970s and has a devoted following among Seiko collectors. The "Save the Ocean" special editions with gradient blue dials regularly sell out and command premiums on the secondary market.

The Promaster BN0150 is the ultimate low-maintenance dive watch. Citizen's Eco-Drive solar movement means you never change a battery — it charges from any light source and runs for months in darkness. The 44mm case with 200m water resistance, unidirectional bezel, and screw-down crown meet ISO 6425 dive watch standards. The polyurethane strap is comfortable and durable in saltwater.

The BN0150 is the go-to recommendation for people who want a dive watch they can wear every day without thinking about winding, power reserve, or battery changes. It is ISO 6425 certified and has been trusted by recreational divers for years.

The Casio Duro is the cheapest legitimate dive watch in the world. At around $50, it delivers 200m water resistance, a unidirectional bezel, screw-down crown, and Casio's proven quartz movement. Bill Gates was famously photographed wearing one, cementing its reputation as the ultimate no-nonsense tool watch. The 44mm case is well-proportioned and the dial is cleanly executed.

The Duro is not a luxury watch, but it is a legitimately capable dive watch that costs less than lunch. The quartz movement keeps excellent time, and the 200m water resistance is real. It is the perfect beater watch for beach days, yard work, or any situation where you do not want to risk a more expensive piece.

Glycine's Combat Sub is the most affordable way to get a Swiss automatic dive watch with an ETA 2824-2 or Sellita SW200 movement. The 42mm case delivers 200m water resistance, a sapphire crystal, and a unidirectional ceramic bezel insert. The brand has been making watches since 1914, and the Combat Sub line has a distinctive vintage military aesthetic with bold color options.

The Combat Sub frequently goes on sale, making it accessible well under $400. The ETA/Sellita movement inside is the same caliber found in dive watches costing two to three times more. Orange, yellow, and bright blue dial options give it a personality that more conservative dive watches lack.

The Tissot Seastar 1000 Powermatic 80 is the most complete dive watch under $500. The 80-hour power reserve Powermatic movement, 300m water resistance, ceramic bezel insert, sapphire crystal, and helium escape valve deliver specs that rival dive watches at $1,000+. The 43mm case is well-finished with a mix of brushed and polished surfaces. Available on bracelet or rubber strap.

The Seastar 1000 is the dive watch to buy if you want the highest possible specs under $500. The 300m water resistance and helium escape valve are overkill for most people, but they demonstrate the level of engineering packed into this price point. Swiss Made credentials seal the deal.

The Invicta Pro Diver uses a Seiko NH35A automatic movement inside a Submariner-inspired 40mm case with 200m water resistance. At $80, you are essentially getting a proven Japanese automatic movement in a stainless steel dive case. The finishing is basic, but the fundamentals — reliable movement, screw-down crown, unidirectional bezel — are all present and functional.

The Pro Diver 8926OB is the cheapest automatic dive watch worth recommending. The Seiko NH35A inside is the same movement found in many watches costing $200-$400. The finishing will not impress watch snobs, but the mechanics are genuinely solid.

The Orient Mako II is the Kamasu's predecessor and remains an excellent value at $180. The in-house F6922 movement, 200m water resistance, day-date complication, and solid bracelet deliver a compelling package. While it uses a mineral crystal instead of the Kamasu's sapphire, the Mako II compensates with a day-date display and slightly more aggressive styling with a wider bezel.

The Mako II is perfect for buyers who want the day-date display that the Kamasu lacks. Both use the same in-house movement, and both are rated to 200m. The Mako II is also one of the most popular affordable dive watches for modding, with a large aftermarket parts ecosystem.

The Seiko 5 Sports SRPD is the spiritual successor to the legendary SKX007. While it is rated to 100m (not 200m like the original SKX), it adds hacking and hand-winding that the SKX lacked. The 42.5mm case with a rotating bezel, day-date display, and dozens of dial color options make it one of the most customizable dive-style watches available. The modding community is enormous.

Note: At 100m WR, this is technically a dive-style sports watch rather than a true dive watch. It handles swimming and snorkeling fine, but for actual scuba diving, choose a 200m-rated option. The SRPD is best thought of as a versatile everyday watch with dive watch aesthetics.

The Marathon GSAR (Government Search and Rescue) is an actual military-issue dive watch, made in Switzerland to US government specifications. It features tritium gas tube lume that glows continuously for 25+ years without needing light exposure, a 41mm fiberglass composite case, 300m water resistance, and a ETA 2824-2 automatic movement. This is a tool watch in the truest sense.

The GSAR is the most purposeful dive watch on this list. It is designed for military and search-and-rescue use, not fashion. The tritium tubes provide constant illumination without needing to charge from light, making it the best option for serious low-light and underwater use. Available with a US government NSN (national stock number) marking.
