Movement Options — NH35, PT5000, SW200
The SN0008 is available with three different automatic movement options, and the correct movement depends on the specific colour variant selected:
NH35 — a Japanese Seiko-based automatic movement, the standard choice across the matte black and matte blue colourways (SN0008C and SN0008D). 24 jewels, 21,600 vph, approximately 41-hour power reserve, with hacking and hand-winding.
PT5000 — manufactured in China by HK Precision Technology, a well-regarded clone of the Swiss ETA 2824-2. 25 jewels, 28,800 vph, approximately 38-hour power reserve, typical accuracy -10/+30 seconds per day. Offered on the gilt, grey, brown, and green colourways as a mid-tier upgrade from NH35.
Sellita SW200 — a genuine Swiss-made automatic movement from Sellita Watch Co., used across established Swiss brands. 26 jewels, 28,800 vph, 38–41-hour power reserve, standard-grade accuracy typically within ±12 seconds per day. The premium movement option on this listing, offered alongside PT5000 on the gilt, grey, brown, blue, and green colourways at a higher price point.
When ordering, confirm the exact movement listed against your selected colour and variant code — do not assume NH35 applies to every option, as PT5000 and SW200 are explicitly offered as separate selections on several colourways.
New Upgraded Construction
This SN0008D version includes several refinements over the earlier SN0008C:
- Screw-structure bracelet — an upgraded link construction method for the solid 316L bracelet, replacing the prior assembly approach.
- Optimised case and bezel edge lines — refined surface transitions between the case and bezel for a smoother, more refined profile.
- HD case and dial detailing — sharper definition on applied indices, the aluminium bezel insert, and the snowflake hands.
Vintage Diver Design
The SN0008 follows a classic retro dive watch layout — applied hour markers, GS Crafts snowflake-style hands, and a 120-click unidirectional rotating bezel with a luminous pip at 12 o’clock. The dial is available in Matte Black Gilt (warm gold-tone indices and text on a black dial), Matte Black, and Matte Blue, plus grey, brown, and green colourways on the higher movement-tier variants. No-logo options are also available for buyers who prefer a cleaner dial without the San Martin branding.
Sapphire Crystal
Sapphire crystal with anti-reflective coating — Mohs 9 hardness, scratch-resistant, with the AR coating reducing glare for improved dial visibility under direct light.
Luminous Details
Lume varies by dial colour: C3 green luminous coating is used on the Matte Black Gilt variant, while BGW-X1 blue luminous coating is used on Matte Black and Matte Blue variants. Both are applied to the hands, hour markers, and the bezel’s 12 o’clock pip.
Screw-Down Crown, Case Back, and 200m Water Resistance
The screw-down crown carries the San Martin 3D hexagon logo and seals against the case to protect against water ingress. The case back is also screw-down with a brushed finish. Combined, these give the watch a genuine 20Bar / 200m water resistance rating — suitable for swimming, snorkelling, and recreational diving. Always ensure the crown is screwed fully closed before water exposure, and avoid operating the crown or bezel underwater.
Solid Stainless Steel Bracelet
The upgraded 316L stainless steel bracelet uses solid links with female end links and the new screw-structure assembly, tapering from 20mm at the lugs to 16mm at the clasp. The folding clasp includes a safety lock and carries the San Martin hexagon logo. Total weight is approximately 145.6g.
Important Care Notes
Calendar adjustment timing: if your selected movement includes a date function, do not adjust the date, day, or month between approximately 8pm and 4am — the calendar mechanism is mechanically engaged during this window, and forcing the adjustment can damage the quickset mechanism.
Manual winding: automatic movements rely on wrist motion for daily winding — wear the watch at least 8 hours per day for consistent accuracy. To manually wind, turn the crown clockwise approximately 15 times with the crown in the closed (non-pulled) position.
Water exposure: if water vapour appears inside the case, a small amount will typically clear on its own within a couple of hours if the watch is worn with the case facing down. Visible water droplets inside the case require prompt servicing.
Magnetic fields: keep the watch away from strong magnetic sources (speakers, magnetic phone mounts, induction equipment) as magnetism can affect mechanical movement accuracy.
Saltwater rinse: rinse the watch with fresh water after saltwater exposure, and have gaskets checked periodically if you use the watch in water frequently, as water resistance can reduce over time.

FAQ
Which movement does my selected colour use? It depends on the variant. Matte Black and Matte Blue (SN0008C/D) typically use NH35. Black Gilt, Grey, Brown, and Green variants are offered with a choice of PT5000 or Sellita SW200. Always check the specific movement listed against your chosen colour and variant code before ordering.
What is the difference between PT5000 and SW200? The PT5000 is a Chinese-manufactured clone of the Swiss ETA 2824-2 — reliable and accurate at a lower price. The SW200 is a genuine Swiss-made Sellita movement with tighter standard accuracy and the credibility of established Swiss manufacture, at a higher price.
Is it waterproof for diving? Yes — 20Bar / 200m water resistance supports swimming, snorkelling, and recreational diving. Ensure the crown is fully screwed down before water exposure.
What is the “new upgrade” on this version? The bracelet now uses a screw-structure link assembly, and the case and bezel edge lines have been refined for a smoother profile compared to the earlier SN0008C version.
Does it come with a warranty? Yes — a 2-year warranty is included.
Can I get this watch without the San Martin logo? Yes — no-logo variants are available on select colourways (PT5000 and SW200 no-logo options are listed).

Top picks just for you
The craftsmanship of the case is particularly excellent. For this price, this is excellent. It's worth 100,000 yen. People who are lost should buy it. Thank you very much. I'll include the Tudor 58 that I have.
Arrives just as described, wears like a dream
A stunner from San Martin, believe the hype around the finishing of these watches, absolutely stunning and a fantastic price. Super fast dispatch and delivery to make the whole experience even sweeter.
Fast ship and exactly as pictured.
The watch is everything they say it is. Can’t fault it in any way. Good build for the price.
a fantastic watch really happy with it and got at a great price. San Martin make fantastic watches at affordable prices
Amazing watch. Very fast shipping. Will order from this store again
Beautiful watch! Came in 6 days
Very nice mechanical watch. Great workmanship. Love it!!
love the watch. good value for money. when on sale just get it.
Great watch - well finished and very comfortable to wear. The weight is nice and doesn’t get in the way. The bezel lines up well with the red triangle and 12 position, and it rotates smoothly in one direction. There is plenty of adjustment in the bracelet - both in links and micro adjustments in the buckle. Tools are included (as in the pictures), though you may need a small hammer to aid with the pin tool to get the pin out. Be careful of adjusting the bracelet as the pins have a sleeve in the link that hold the pin in place. I’ve added a picture of the link, pin, and pin sleeve. If you lose the sleeve, the pin is very loose and may slide right out. Very good package with tools, cards, and manual. Overall, very satisfied with the purchase.
Fast delivery and well packaged as expected.
Excellent watch. Fit and finishing are at the highest level. Links are held together with a very unique cap-screw and loose pin system. Other than that, i really appreciate this product. Highly recommend this seller.
Such a great watch! I want one in every color
Great looking watch. getting a lot of compliments. just what the doctor ordered.
Great watch first san martin and i'm impressed. Would recommend.

Nice timepiece The only disappointment is about sharp edges in some places I'm ready to recommend this watch as a very good offer
Excellent watch. As good as swiss. Ticks all the boxes. Inc. price.

Incredible value for money. Compliment magnet! The green color is gorgeous. Fast delivery, great communication. Waiting for the sn006 to be in stock. Buying again!
