San Martin Automatic Diver - Classic Size Four

You get a professional-grade diver watch that performs reliably and turns heads every time you check your wrist. The matte black dial pairs with a solid stainless steel build to give you serious dive credentials and polished everyday style.

  • Screw-Down Helium Escape Valve: Protects the crystal during deep saturation dives and supports a true 600-meter water resistance depth.
  • On-The-Fly Adjustable Clasp: Lets you tweak the bracelet length to comfort over sleeves or wetsuits without tools.
  • High-Integrity Lume Application: Uses BGW-X1 and C3 materials on hands and markers so you read time clearly in pitch-dark conditions.
  • Scratch-Resistant Sapphire Glass: Features anti-reflective coating and stands up to daily scrapes and adventures in the environment.
  • Precision Automatic Movement: The reliable ST 2130 caliber delivers steady performance with a 40-hour power reserve and smooth sweeping seconds hand.

This San Martin diver is built for the person who refuses to compromise between durability and elegance. The matte black dial sits behind sapphire crystal, framed by a unidirectional ceramic bezel with crisp markings. A date window at three o'clock adds function to the balanced layout. Broad arrow hands sweep with precision, while the screw-down crown bears a raised hexagonal logo that nods to craftsmanship without shouting for attention.

If you want a watch that handles salt spray, gym sessions, and business casual outfits equally well, this piece fits seamlessly into your rotation. The chamfered bracelet contours smoothly to your wrist, eliminating gaps and digging edges even on smaller wrists. You wear it to feel secure and looked-after in every setting.

The 316L stainless steel construction resists corrosion and carries a satisfying heft at roughly 179 grams. Brushed surfaces diffuse fingerprints while polished chamfer lines catch light beautifully. Whether you are monitoring time underwater or making quick notes above deck, you appreciate a tool you can trust.

Key Benefits

  • Fit Customization: Adjust the bracelet size mid-wear to maintain optimal comfort throughout changing temperatures or clothing layers.
  • Vision Assurance: Superluminara treatment ensures maximum glow retention and legibility across all lighting scenarios.
  • Corrosion Shield: Premium stainless steel alloys withstand harsh environments and maintain a pristine appearance over years of frequent wear.
  • Scarfless Time Reading: Applied indices and broad arrow pointers create sharp contrast against the matte background for instantaneous clarity.

Features

  • Ceramic Bezel Insert: Offers scratch-resistant fading resistance with vivid color options including black, blue, and orange finishes.
  • Screw-Down Case Back: Seals the movement compartment with a brushed finish and ensures integrity at significant pressure depths.
  • AR Coated Sapphire: Multi-coating reduces glare reflections so you can check readings clearly under direct sunlight.
  • Broad Arrow Indicators: Classic diver typography provides recognition and balances proportions on the compact dial face.
  • Hexagonal Design Accents: The crown and clasp feature custom 3D hexagon logos that reinforce brand identity and design cohesion.

Frequently Asked Questions

What steps should I take if I notice condensation inside the watch glass?

A few droplets indicate a seal breach requiring immediate professional servicing. Small vaporous traces often resolve naturally over several days or by storing the watch upside down on a warm surface, though inspection remains recommended to preserve movement health.

Can I manually set the hands to correct time discrepancies?

Rotation of the crown pulls out to set seconds for precision synchronization. Turn counter-clockwise until the stem extends fully, then advance hands to match GPS reference before pushing back to engage automatic mode securely.

I do not recommend buying watches from San Martin, it's overrated ****. I looked at many reviews of these watches and it's clear that San Martin simply paid for these reviews. Let me start with the first one: delivery: it was a bit delayed, but the seller fulfilled my request regarding it, for that I give them respect. Watch: The watch itself looks nice, the dial is slightly grayish, it was very foolish to use a matte gray dial instead of black enamel, the bezel on my watch broke after 2 days! It stopped working properly and got stuck. There are no complaints about the case, except that the date on my watch was positioned low. which again indicates poor quality control. The bracelet on the watch is beautiful, but how terrible it is... it's so sharp that the watch can't be worn for more than half a day, although San Martin is constantly bragging about its craftsmanship quality. 😂 😂 😂 This isn't even a level of orientation! There is no sharp spot on my orient at all. The clasp on my watch is not working properly; it rarely fastens properly.

This watch is stunning in person. quality from bezel to case is outstanding. haven’t sized the bracelet yet

Finished well and feels good. Be wary if you've hairy wrists, braclet does pull hairs when put on/taken off due to the articulation as braclet doesn't fold back on itself far, when it's on wrist there isn't any discomfort.

Main issues (posted prior to contacting san martin, i'll update the review with any updates):

Bezel alignment: mine is misaligned, wish it hadn't slipped past qc.

My hour hand isn't perfectly aligned when the minute hits 60. Small but it bugs me, i don't know if this is a product of the movement or just wasn't alligned on assembly.

Noticeable wedge shape on a lug where it meets the endlink due to rounded metal. Shame as the bracelet and endlinks are very well done but in areas like this the case isn't to the same standard.

These may all seem like small things but for a brand who heavily advertises their superior qc standards on their socials i'd have hoped better. As said earlier i'll contact san martin and see if they have anything to say on the matter.

Not very good
First of all, the design is tacky. I think the case and bracelet of this watch have a sporty feel and are an homage to Omega's Planet Ocean, but the dot-shaped indices make it feel like an old-fashioned watch.
Case and index do not match. I think the bar index was good. Also, if you want to add some originality to the dial, you could have used black enamel or something similar, but the matte black that halfway imitates PO makes it look quite tacky.
The finish of the case is very good, but as shown in photo 2, the center of the rotating bezel is slightly off to the left.
It's not the quality of a watch that costs 50,000 yen.
It's wiser to buy a more subdued watch from Orient or Sugess.

Great quality watch! Despite the price, it's worth it. I still think it's better than an Orient Submariner 39mm. A 41mm watch that fits like a 39.5 or 40mm. Congratulations to SAN MARTIN for the great product. First of many to come.

Stunning and sensibly sized po homage. ysual faultless san martin quality. yes, prices are rising on ali but some brands are just worth what is ultimately a much reduced price versus the 'real thing'. 41mm works much better and thickness is pretty good for a600m rated diver. no complaints

Another beauty from san martin.

Ordered on 01.07.2026, delivered on 25.07.2026, already 5 days late. The screwdriver provided by San Martin for the strap does not fit into the screw slots. What do people do when they don't have watchmaker tools? 😏 The watch itself makes a good impression at first glance. Unfortunately, buying through AliExpress is no longer worth it with €56 in customs and import taxes.

Nguyet Lowe

It is genuinely impressive what this watch offers for the money. i like the slightly chunkier thickness and weight, and the 600m is cool (althoght overkill for me). what really stands out is the effort on the case polishing and especially the bracelet. the bracelet is brilliant, i have two longines and the bracelet is completely comparable in fit and finish. brilliant timepiece.

San martin at their best.



I'll start with the good, case finishing is the best i've seen, not just as this price, but at 10x the cost. Per usual with san martin, lume is bright and packed in for hours of legibility. Bracelet is immaculate with no smudging between finishing.



The qc on my watch is great, bezel aligned, not a single speck of dust under the crystal, signed crown screws all the way it to be aligned at 12, date change dead on at midnight. I commend them for this.



Now for the negatives, only 2. Firstly, the on the fly adjustment clasp is difficult to use, it skips slots, won't always engage the smallest position, and the button is spongy with no feedback, might just be my unit though. Secondly, my bezel action is gritty, not much, but it grinds up and sticks which suggests there is a small particle between the bezel and the case.



Overall, especially with discounts, this watch is 100% worth a pickup if you want a good sized, high beat, dive style watch.

Fit and finish is exceptional and the polishing of the bracelet makes for a dazzling display of reflections and scattered light. the ar coating could be a bit better. i was surprised to see how well polished the ceramic insert in the bezel was. the case does not feel bulky, although the weight can be felt on the wrist. in terms of the movement, i can see why some people may feel like the weak point is the stem as it feels a bit too tight to wind and as a result, i rather put this one on a watch winder. overall i am very satisfied with my purchase.

I have bought several san martin watches so far this one is the most satisfying one i’ve on my wrist and the st2130 movement has performed with high accuracy comparable to seiko spb143j, the watch body is clean and beautiful except for the slightly sharp feel to the touch on the middle links of the bracelet.
