Chinese dive watches have become a serious part of the enthusiast-watch market, with current models offering sapphire crystals, automatic movements, titanium cases, strong lume and practical water-resistance specifications across a wide range of prices.
This guide compares five current dive watches carried by Watchdives from Watchdives, San Martin, Octopus Kraken, ADDIESDIVE and Tactical Frog. The goal is not to rank one universal winner. Instead, each model represents a different priority: lightweight titanium, compact steel, value, classic automatic construction or fixed-bar tool-watch character.

1. Watchdives WD007 V4 — Titanium and High-Beat Movement Choice
The Watchdives WD007 V4 is built around a 42mm Grade 2 titanium case. At the latest check it had multiple purchasable configurations and a total inventory count above 200 units, making it one of the better-supported current options in this comparison.
Movement depends on the selected variant. Current versions use either the PT5000 or Peacock SL3001, both running at 28,800 vibrations per hour / 4Hz. The watch also uses a double-domed sapphire crystal, 120-click unidirectional bezel, screw-down crown and a stated 200m water-resistance rating.
Dimensions are 42mm across, 48.95mm lug to lug and 12.2mm thick including the domed crystal. Band choices vary by configuration and include nylon, mesh, Grade 2 titanium bracelet and FKM rubber.
Consider the WD007 V4 if: you want the low weight of titanium, prefer a larger tool-watch case and value the choice between two high-beat automatic movements. For a movement-level comparison, see our SL3001 vs PT5000 guide.
2. San Martin SN0116 — Compact Steel Diver with Colorful Dials
The San Martin SN0116 takes a more compact steel approach. Its 39.5mm case, 46.5mm lug-to-lug measurement and 12.2mm thickness keep the footprint moderate for an automatic dive watch.
It uses a Japan NH35A automatic movement, sapphire crystal with AR coating and a 120-click unidirectional sapphire bezel with luminous markers. The current listing specifies 200m water resistance, a screw-down crown, a beads-of-rice style steel bracelet and an on-the-fly adjustable clasp.
Current purchasable versions include Rainbow Bezel, Avocado Green and Orange at the latest check. The Grape Purple version was sold out at that time.
Consider the SN0116 if: you want a sub-40mm steel automatic diver, prefer more expressive dial colors and value a bracelet with quick adjustment.
3. Octopus Kraken OCT0018 — 39mm NH35 Simplicity
The Octopus Kraken OCT0018 is the simplest proposition in this group: a 39mm 316L stainless-steel diver powered by the NH35 automatic movement.
Its current specification includes a sapphire crystal with AR coating, a 120-click unidirectional bezel, Swiss C3 green lume, screw-down crown and screw-back case. It measures 48mm lug to lug and 12.5mm thick excluding the crystal.
All three current dial variants—Blue, Black with white indices and Vintage Black with yellow indices—were purchasable at the latest check, with a combined inventory of 69 units.
The current product page describes dive-watch construction but does not fix one universal water-resistance number for every production batch. We therefore do not invent a rating here: check the selected current listing before buying if a specific depth rating is important to you.
Consider the OCT0018 if: you want a 39mm NH35-powered automatic diver with conventional steel construction and a straightforward three-color range.
4. ADDIESDIVE AD2081 — Larger Vintage-Inspired Value Pick
The ADDIESDIVE AD2081 uses a much broader 43.8mm stainless-steel case, but its 46.8mm lug-to-lug measurement keeps its top-to-bottom span relatively restrained for the diameter.
It uses a Japan NH35 automatic movement with a listed approximately 41-hour reserve, sapphire crystal with AR coating, 120-click unidirectional ceramic bezel, screw-down crown, Swiss BGW9 lume and a stated 200m / 20 ATM water-resistance rating.
Blue, Black and Orange dial variants were all currently purchasable at the latest check, with 50 units of inventory in total. The listed price was $149 across the three versions.
Consider the AD2081 if: you want a larger vintage-inspired diver, prefer the familiar NH35 platform and want to keep the current purchase price lower than the other automatic models in this comparison.
5. Tactical Frog FX-Diving V4 — Fixed-Bar Titanium Tool Watch
The Tactical Frog FX-Diving V4 is the most specialized design here. Its 42mm titanium case uses fixed strap bars rather than conventional removable spring-bar lugs.
The current V4 uses a Hangzhou 2565 automatic movement, sapphire crystal with AR coating, screw-down crown, BGW9 blue lume and a bidirectional titanium bezel with a ceramic insert and 60-minute navigation scale. Water resistance is listed at 200m / 20 ATM.
Its 42mm case measures 13.31mm thick including the crystal. The supplied fabric strap uses a titanium buckle. All five current dial configurations were purchasable at the latest check, with a combined inventory of 108 units.
Consider the FX-Diving V4 if: you specifically like fixed-bar tool watches, titanium construction and the look and feel of a fabric-strap diver rather than a conventional bracelet-led design.
How to Choose a Chinese Dive Watch
Start with wrist dimensions, not just diameter
Case diameter is only one part of fit. The SN0116 is 39.5mm with a 46.5mm lug-to-lug measurement, while the 42mm WD007 V4 stretches to 48.95mm. The AD2081 is wider at 43.8mm but measures only 46.8mm lug to lug. Compare diameter, lug-to-lug and thickness together.
Choose steel or titanium deliberately
Steel gives the SN0116, OCT0018 and AD2081 a more traditional watch feel. Titanium reduces case weight on the WD007 V4 and Tactical Frog FX-Diving V4. For a deeper material comparison, read our Titanium vs Stainless Steel Watches guide.
Movement name is only one part of the watch
NH35 is used in the SN0116, OCT0018 and AD2081, while the WD007 V4 offers PT5000 or SL3001 variants and the Tactical Frog uses a Hangzhou 2565. Movement choice affects the ownership experience, but crystal, case, bezel, crown, water resistance, bracelet and quality control matter just as much.

Frequently Asked Questions
Are Chinese dive watches worth considering?
They can be. The current market includes models with sapphire crystals, reliable Japanese and Chinese automatic movements, titanium or stainless-steel cases, strong lume and substantial water-resistance specifications. The useful comparison is the complete watch and current product support rather than country of origin alone.
What automatic movements are common in Chinese dive watches?
Current examples on Watchdives use movements including Seiko/TMI-family NH35, PT5000, Peacock SL3001 and Hangzhou calibres. The exact movement depends on the model and sometimes on the selected variant.
Are all Chinese dive watches large?
No. Current examples range from the 39mm OCT0018 and 39.5mm SN0116 to 42mm titanium tool watches and the broader 43.8mm AD2081. Compact 37–38mm dive watches also exist elsewhere in the current catalog.
Is titanium better than stainless steel for a dive watch?
Not universally. Titanium is lighter and highly corrosion resistant, while stainless steel offers a more traditional sense of weight and familiar finishing. Water capability depends on the complete watch construction and testing rather than case material alone.
Does a water-resistance number mean formal dive-watch certification?
No. A manufacturer's stated water-resistance rating and formal compliance with a specific diving-watch standard are different claims. Follow the exact model's documentation and intended-use guidance.
Final Takeaway
The Chinese dive-watch category is broad enough that there is no single model that fits every buyer. The WD007 V4 emphasizes titanium and high-beat movement choice; the SN0116 offers compact steel proportions and colorful configurations; the OCT0018 keeps the formula simple at 39mm; the AD2081 emphasizes value and larger vintage styling; and the Tactical Frog FX-Diving V4 takes a more specialized fixed-bar titanium approach.
Compare the complete watch rather than shopping from one specification alone. For more current models, browse our Dive Watches collection or see our broader Best Dive Watches 2026 guide.
