San Martin SN0017 Classic Automatic Diver Watch — PT5000 or NH35, 40mm, 200m

The San Martin SN0017 Classic Diver is a 40mm automatic dive watch available with PT5000 or NH35 movement — selected at purchase. 120-click unidirectional ceramic bezel, sapphire crystal with AR coating, BGW9 blue-white lume on all hands and indices, screw-down crown with hexagonal logo engraving, 4-hole micro-adjust folding clasp and 200m water resistance. Available in sunray green, enamel black and black/green bezel configurations.

Key Specifications

Movement Choice — PT5000 or NH35

PT5000 (recommended for smoothest seconds sweep): 28,800 vph — 8 beats per second rather than NH35’s 6. The higher beat rate creates a noticeably smoother seconds sweep. ETA 2824-2 architecture from SII (Seiko Instruments International) — Swiss-pattern engineering. Hacking and hand-winding. At 11.6mm total case thickness the PT5000 version is 1.1mm slimmer than the NH35 version.

Seiko NH35 (recommended for serviceability): 21,600 vph, 41-hour power reserve. The most globally serviceable automatic movement — any watchmaker worldwide can work on it. Hacking and hand-winding. At 12.7mm the NH35 version is slightly thicker.

Which to choose: PT5000 for the smoother sweep and slimmer 11.6mm profile. NH35 for the widest global service network. Both hack and hand-wind — no disadvantage on that front.

Variants — Seven Configurations

Sunray Green / Green Ceramic Bezel (PT5000 or NH35): A sunray-finished green dial paired with a matching green ceramic bezel. The green-on-green combination creates a monochromatic sport-dive character that is specifically collected — green dial divers have been among the most discussed colour preferences in the affordable watch community for several years.

Enamel Black / Black Ceramic Bezel (PT5000 or NH35): The enamel dial is the most unusual specification in the SN0017 range. True enamel dial — vitreous glass fused to the dial base at high temperature — creates a deep, glossy surface with a visual depth that sunburst or painted dials cannot match. Enamel on a 200m diver at this price is extremely unusual; most enamel dials appear on dress watches at much higher price points. The black enamel combined with the black ceramic bezel creates a fully dark, deeply glossy dial face.

Enamel Green / Black Ceramic Bezel (ST version): Green enamel dial on black ceramic bezel — the combination of enamel texture and green colour is the rarest and most distinctive of the seven.

Black / Green Ceramic Bezel (PT5000 or NH35): Standard black dial with contrasting green ceramic bezel — the most widely collected two-tone diver colour combination. The black and green contrast is the most sport-oriented of the configurations.

Enamel Dial — What It Means

Vitreous enamel is produced by fusing powdered glass onto the dial base at temperatures above 700°C. The result is a surface that is harder than standard lacquer or print, deeply glossy and immune to the fading that affects other dial finishes over decades of wear. Under direct light the enamel surface has a visual depth — the transparent glass layers above the colour base create an apparent depth that flat printed dials lack.

On a dive watch, enamel is an unconventional choice — enamel dials are associated with formal dress watches and are rarely seen on instruments designed for water use. The San Martin SN0017 enamel variants combine this material with a 200m-rated case, creating a watch that reads as both visually sophisticated and technically capable.

Bracelet and Clasp

The 316L bracelet tapers from 20mm at the lugs to 16mm at the clasp — a traditional taper that creates a lighter wrist feel than uniform-width bracelets. Screw-pinned links provide structural security and allow individual link removal for sizing. The folding safety clasp includes 4 micro-adjust holes — additional size adjustment without link removal, useful for wrist size variation during activity.

The San Martin hexagonal logo is engraved on both the crown and the clasp exterior.

BGW9 Lume

BGW9 Super-LumiNova’s blue-white formulation on all hands and indices — the highest-intensity standard lume. The luminous bezel pip at 12 o’clock is also BGW9. After light exposure the watch presents a cohesive blue-white glow across every lume element.

How It Compares

vs. Phylida SE-11 — The Phylida SE-11 uses Miyota 8215 at 41mm / 200m with 120-click ceramic bezel and double-domed sapphire. The SN0017 offers PT5000 at 40mm with enamel dial options and 11.6mm thickness (vs SE-11’s 14.1mm). The SN0017 is the slimmer option with premium movement and enamel dial; the SE-11 is the wave-dial alternative.

vs. Pagani Design PD-1685 V2 — The PD-1685 uses Miyota 8215 at 42mm / 200m with wave-pattern dial. The SN0017 is 40mm with PT5000 or NH35 and the enamel dial option. San Martin’s bracelet finishing and clasp quality is typically considered a step above Pagani Design.

vs. IXDAO JD-X02T Bronze — The IXDAO uses PT5000 in a CuSn8 full bronze case. The SN0017 is the stainless steel alternative with PT5000 at 200m.

Who Is the San Martin SN0017 For?

The SN0017 is built for:

• PT5000 buyers who want the ETA 2824-2 architecture in a 200m ceramic bezel diver at the thinnest available profile (11.6mm)
• Enamel dial buyers who want vitreous enamel on a capable dive specification — one of the very few enamel dive watches available under $400
• Green diver collectors who want the monochromatic green dial + green bezel combination on a well-finished 40mm case
• San Martin buyers who want the brand’s known bracelet quality and finishing at the 200m entry-level price
