San Martin SN0150 Guilloché Mother-of-Pearl Watch — Miyota 9015, 39mm, 10.2mm

San Martin SN0150 Guilloché Mother-of-Pearl Watch — Miyota 9015, 39mm, 10.2mm

The San Martin SN0150 is a 39mm Miyota 9015 automatic dress-sport watch with a guilloché mother-of-pearl dial — a multi-layer surface where an engraved geometric guilloché pattern underlies translucent MOP, creating simultaneous depth and iridescence. At 10.2mm total thickness it is the slimmest San Martin in the range. Solid 316L H-link bracelet with fly-adjust clasp, sapphire crystal with AR coating, BGW9 blue lume and 100m water resistance.

Available in five configurations: guilloché black MOP, guilloché white MOP, purple-blue MOP, blue-red MOP and green-yellow MOP.

Key Specifications

Variants — Five Guilloché MOP Configurations

Guilloché black MOP: Deep black mother-of-pearl with guilloché engraving beneath. The iridescence is subtlest on the black MOP — visible as colour shifts from black toward deep blue-green under direct light. The most formally assertive configuration.

Guilloché white MOP: White or cream MOP with guilloché pattern. The most classically formal — white MOP’s iridescence is clearest against the applied indices. The traditional formal dress watch combination.

Purple-blue MOP: A violet-to-blue tonal MOP — the guilloché creates directional depth within the purple-blue field. One of the more distinctive MOP colour combinations available in this price category.

Blue-red MOP: Blue MOP with red tonal shifts — the colour contrast within the MOP material creates a visually active dial that changes direction under different light sources.

Green-yellow MOP: A warm green MOP with yellow undertones. Under warm indoor light the green-yellow shifts toward olive-gold; under cool daylight it reads as fresh green. The most unusual and collector-oriented of the five configurations.

Guilloché Under Mother-of-Pearl

The SN0150’s dial layers two heritage materials simultaneously:

Guilloché is a geometric engraved pattern on the dial base — fine lines cut by a rose engine lathe or CNC equivalent. The guilloché creates a structured three-dimensional texture beneath the MOP layer.

Mother-of-pearl is the nacre inner lining of mollusc shells, cut into thin translucent panels. MOP is semi-transparent — light passes through it, reflects off the guilloché pattern beneath and returns through the MOP, creating depth and iridescence simultaneously.

The combination means the dial reads differently at every angle and light condition. Directly overhead the MOP shows its iridescent surface character. At an angle the guilloché pattern beneath becomes visible through the translucent MOP. Under changing light both elements shift simultaneously. Each dial panel is unique — natural MOP growth characteristics create individual variation in every piece.

Miyota 9015 at 10.2mm

The 9015’s slim movement architecture enables the 10.2mm case height — one of the thinnest automatic watches available at this specification level. At 28,800 vph the seconds sweep is smooth and indistinguishable from higher-priced movements at this beat rate. Hacking stops the seconds for precise time-setting; hand-winding tops up the reserve without wearing the watch.

At 10.2mm the SN0150 clears any shirt cuff with no lift and sits flat against the wrist. Among San Martin models at Jewelry Addicts this is the thinnest automatic by over a millimetre.

H-Link Bracelet and Fly-Adjust Clasp

The solid H-link bracelet uses a specific internal construction that provides rigidity with reduced per-link weight. It tapers from 20mm at the lugs to 16mm at the clasp — proportionally appropriate for the 39mm case. The fly-adjust clasp allows effective bracelet length adjustment in small increments without removing links — useful for wrist size variation across the day.

Who Is the San Martin SN0150 For?

The SN0150 is built for:

• Buyers who want guilloché MOP on a capable everyday watch — the dial combination is typically found on dress watches at significantly higher prices
• Green-yellow or purple-blue MOP buyers who want unusual dial colour character on a slim bracelet automatic
• 10.2mm slim profile buyers who need a bracelet watch that clears formal shirt cuffs
• Miyota 9015 buyers who want the high-beat smooth sweep in a dress-sport format
• GADA buyers who want one watch covering office, travel and evening contexts at 39mm

How It Compares

vs. San Martin SN0017 Classic Diver — The SN0017 is 40mm at 200m with PT5000 or NH35. The SN0150 is 39mm at 100m with Miyota 9015 and the guilloché MOP dial. The SN0017 is the capable diver; the SN0150 is the slim dress-sport alternative.

vs. Sugess S455 Blue Goldstone — The Sugess is 8.9mm / 38mm with distinctive mineral-glass dial and ST2130. The SN0150 is 10.2mm / 39mm with MOP and bracelet. Both are thin watches with unusual dial materials — different dial character and strap format.

vs. Proxima PX1721 Aventurine — The Proxima uses natural aventurine at 200m on PT5000/SW200 with full BGW9 lume bezel. The SN0150 is the slim bracelet MOP alternative at 100m.

vs. Sugess S449 MOP Heritage — The Sugess S449 uses plain MOP without guilloché on a day-date automatic. The SN0150 adds the guilloché layer under the MOP on a slimmer case.

3D Oil-pressed Screw-down Case Back, Engraved with Chinese stamp “Made in San Martin”, inspired by the stamp on the bottom of Chinese porcelain “JianZhan”.

We refer to the way Chinese porcelain is stamped with the name of the manufacturer on the bottom. This stamp is an official certification that indicates its origin and manufacturer. Now many very fine porcelains auctioned at auctions have information about the manufacturer or the year on the bottom.
The outer circle is some information about the brand and model, and the middle is the seal script Chinese made by San Martin, which makes it integrate more Chinese culture and original design elements.
