A dive watch under $300 gives you reliable water resistance, a unidirectional bezel for timing dives, and a tool watch aesthetic that works on land too. Here are the best options for 2026.
1. Orient Kamasu
Orient builds the Kamasu with an in-house automatic movement, sapphire crystal, 200-meter water resistance, and a solid stainless steel bracelet. The sunburst dial catches light beautifully.
The unidirectional bezel clicks firmly with 120 positions. About $280. For a mechanical dive watch with a sapphire crystal at this price, the Kamasu is hard to beat.
2. Seiko Prospex SPB143
Seiko's SPB143 uses the 6R35 automatic movement with 70-hour power reserve. 200-meter water resistance. Sapphire crystal with anti-reflective coating. The case design pays homage to Seiko's 1965 dive watch.
About $300. Seiko dive watches have a legendary reputation for reliability, and the SPB143 lives up to it.
3. Casio G-Shock Frogman GW-8230
The Frogman is a purpose-built digital dive watch. ISO 200-meter water resistance. Tough Solar charges from light. Multi-Band 6 atomic timekeeping. Tide graph and moon data for divers and surfers. About $280.
The G-Shock construction makes it the toughest dive watch at any price. Virtually indestructible.
4. Citizen Promaster Diver BN0151
Citizen's Eco-Drive technology means this watch never needs a battery. Light from any source keeps it running. 200-meter water resistance. Unidirectional bezel. Mineral crystal. About $200. The reliability of solar power combined with Citizen's build quality makes this a low-maintenance dive watch.
What to Look For
200-meter water resistance is the minimum for actual diving.
Unidirectional bezels prevent accidental over-timing of dives. Sapphire crystals resist scratches better than mineral glass. Screw-down crowns improve water resistance. Lume on the dial and hands must be bright enough to read at depth.
