Best Dive Watches Under $300 (2026 Buying Guide)
Dive watches under $300 are no longer just chunky “desk-divers.” In 2026 you can get real 200–300 m water resistance, screw-down crowns, strong lume, and even sapphire crystals and ceramic bezels — all without paying luxury money.
This guide focuses on analog dive watches, not dive computers. These are great for recreational diving, snorkeling, and as rugged everyday watches — and they can also serve as a simple backup timer next to your dive computer.
Best Dive Watches Under $300 in 2026
Citizen Promaster Diver Eco-Drive BN0150
Best overall dive watch under $300
Key Specs (BN0150-28E / BN0151 variants):
- Movement: Citizen Eco-Drive solar quartz (no battery change)
- Water resistance: 200 m, ISO 6425-compliant diver
- Case size: ~44 mm, stainless steel, screw-down crown
- Crystal: Mineral (Citizen’s hardened glass)
- Bezel: 120-click unidirectional dive bezel
Why it stands out:
The BN0150 Promaster Diver is the “default answer” when someone asks for a serious, affordable dive watch. It’s ISO 6425-certified, meaning it passes impact, thermal shock, and over-pressure tests that generic “200 m WR” watches may not.
Citizen’s Eco-Drive movement charges from any light source, so you don’t have to worry about battery changes compromising the seals before a trip. The bezel action is crisp, legibility is excellent with big hands and indices, and the rubber strap is comfortable in water.
Best for:
Divers and everyday users who want set-and-forget reliability with real dive credentials and minimal maintenance.
Orient Kamasu (RA-AA0001B / RA-AA0002L etc.)
Best affordable automatic diver
Key Specs (Kamasu “I” family):
- Movement: Orient F6922 automatic (hacking & hand-winding)
- Water resistance: 200 m
- Case size: ~41.8 mm, 47 mm lug-to-lug
- Crystal: Sapphire
- Bezel: 120-click dive bezel
Why it stands out:
The Orient Kamasu is the gateway into mechanical divers. You get a true automatic movement, sapphire crystal, and 200 m water resistance for a street price that usually lands well under $300.
It wears nicely on most wrists thanks to the compact lug-to-lug length, and comes in multiple dial colors (black, green, red, blue). The lume is strong for the price, the bezel is easy to grip with wet hands, and the in-house movement has a reputation for taking abuse.
Best for:
Watch enthusiasts who want a mechanical dive watch with sapphire and classic looks without paying mid-range Swiss prices.
Casio MDV106-1A “Duro”
Best ultra-budget beater dive watch
Key Specs:
- Movement: Japanese quartz
- Water resistance: 200 m
- Case size: 44 mm
- Crystal: Mineral
- Bezel: 60-click unidirectional bezel
Why it stands out:
The Casio MDV106 (often called the “Duro”) is legendary for what it offers around the $50–$80 mark. You get 200 m water resistance, screw-down crown, and a proper dive bezel in a simple, reliable package.
It doesn’t have sapphire, ceramic, or fancy finishing — but that’s the point. This is the watch you happily bash against a boat ladder or rock without anxiety. Swap the rubber strap for a NATO or bracelet and you have a cheap, tough daily beater that can still handle real water use.
Best for:
Anyone who wants a true 200 m dive watch on a tiny budget, or a rough-use backup to a more expensive diver.
Seiko Prospex Solar Diver (SNE57x Series)
Best compact solar diver around $300
Key Specs (e.g., SNE571 / SNE573):
- Movement: Seiko solar quartz
- Water resistance: 200 m, ISO-rated diver
- Case size: ~38.5 mm (great for smaller wrists)
- Crystal: Sapphire
- Bezel: 120-click unidirectional bezel
Why it stands out:
Seiko’s compact Prospex Solar Diver line (SNE57x) brings together ISO-rated 200 m resistance, sapphire crystal, and classic Seiko diver design in a very wearable ~38.5 mm case.
Solar charging means you avoid battery swaps, while Seiko’s LumiBrite lume is famously bright and long-lasting. Pricing fluctuates, but these models are often found around or just under $300 from major retailers and on Amazon. Always check current pricing, as watch prices move.
Best for:
Divers and enthusiasts who want a smaller, solar-powered Seiko diver with proper specs and great lume.
Phoibos Wave Master (PY010)
Best spec monster under $300
Key Specs (e.g., PY010C):
- Movement: SII NH35A automatic
- Water resistance: 300 m (1000 ft)
- Case size: 42 mm, 316L stainless steel
- Crystal: Sapphire with AR coating
- Bezel: 120-click ceramic unidirectional bezel
- Lume: Swiss Super-LumiNova BGW9 / Dark Blue
Why it stands out:
The Phoibos Wave Master is the classic “how did they pack this much in under $300?” kind of watch. You get 300 m water resistance, sapphire crystal, ceramic bezel, a solid bracelet, and a reliable NH35A movement.
The wave-pattern dial gives it character without hurting legibility, and the lume is genuinely strong. This one is often recommended by enthusiasts as a spec-rich alternative to mainstream brands, and it’s typically sold in the mid-$200s.
Best for:
Buyers who want maxed-out specs (300 m WR, sapphire, ceramic bezel, strong lume) while still staying in the sub-$300 range.
Invicta Pro Diver 8926OB
Best cheap Sub-style automatic
Key Specs:
- Movement: Seiko NH35A automatic
- Water resistance: 200 m
- Case size: ~40 mm
- Crystal: Mineral
- Bezel: Unidirectional dive bezel with coin-edge (“OB”)
Why it stands out:
The Invicta Pro Diver 8926OB divides opinion in the watch world, but it offers a lot for its usual $80–$120 street price. You get a 200 m-rated case, NH35A automatic movement, and classic Submariner-style looks that many people simply like.
Finishing is not on the level of higher-priced pieces and the bracelet is basic, but as a starter automatic dive watch with real water resistance, it’s hard to ignore.
Best for:
Newcomers who want a very affordable automatic diver with familiar styling and decent specs.

How to Choose a Good Budget Dive Watch
When you’re trying to stay under $300, it helps to focus on core dive-watch fundamentals instead of brand hype.
1. Water Resistance & Standards
- Look for at least 200 m water resistance for real diving and serious water use.
- Some models like the Citizen Promaster BN0150 and Seiko Prospex Solar are ISO 6425-compliant divers, which means they’ve passed specific tests for diver’s watches.
2. Bezel Quality
- A proper dive watch should have a unidirectional bezel that turns only counter-clockwise, with clear minute markings and a lume pip at 12.
- Cheap bezels can feel mushy or misaligned; models like the Kamasu, Promaster, and Wave Master generally have good bezel action in this price tier.
3. Legibility & Lume
- Underwater (and at night), high contrast hands and indices are more important than fancy dial textures.
- Strong lume (Citizen, Seiko LumiBrite, Super-LumiNova on Phoibos) makes it much easier to time safety stops and ascent rates.
4. Movement: Quartz vs Automatic
- Quartz / solar: More accurate, lower maintenance, usually thinner and cheaper. Great if you want a grab-and-go tool.
- Automatic: Mechanical charm, sweeping seconds hand, no battery — but thicker and needs periodic servicing.
In this list:
- Citizen BN0150 and Seiko SNE57x = solar (best low-maintenance picks).
- Orient Kamasu, Phoibos Wave Master, Invicta Pro Diver = automatic.
5. Size & Fit
- Many older divers are 44–45 mm, which can feel huge on smaller wrists.
- If you want something more compact, look at:
- Seiko SNE57x (~38.5 mm)
- Kamasu (~41.8 mm but short lug-to-lug)
6. Strap / Bracelet
- Rubber/FKM straps are more comfortable in water and easier to rinse.
- Steel bracelets add weight and versatility for daily wear.
- Many of these watches use standard lug widths (20–22 mm), so you can easily swap straps to suit your style.
