San Martin SN0144 – 39mm Automatic Watch with Miyota 9015 Movement | Sapphire Crystal & 100M Water Resistance

Elevate your wristwear with the San Martin SN0144, a 39mm automatic watch that blends technical mastery with timeless design. Created for those who appreciate both mechanical precision and modern aesthetics, this watch delivers an effortless balance of function and flair—whether you’re at the office, on the road, or off the grid.

At its core beats the renowned Miyota 9015 movement, revered for its slim profile, dependable accuracy, and smooth 28,800 bph sweep. Encased in brushed 316L stainless steel, the SN0144 features a compact yet confident silhouette, fitting comfortably on most wrists without sacrificing wrist presence.

A standout feature is the wave-textured dial, available in captivating shades like deep blue, sunburst orange, and crimson red—each layered with depth, contrast, and luminous detailing for visibility day or night. The sapphire crystal glass offers maximum scratch resistance, while the 100-meter water resistance rating makes it a reliable companion for both daily wear and light aquatic adventures.

Why It Stands Out

  • Miyota 9015 Automatic Movement: Japan’s trusted high-beat engine with hacking and hand-winding
  • Sapphire Crystal: Clear, durable, and scratch-resistant for long-term clarity
  • Wave-Pattern Dial: Subtle texture adds depth and personality to each colorway
  • Luminous Hands & Markers: Easy readability in low-light conditions
  • 100M Water Resistance: Swim, shower, or explore with peace of mind
  • 39mm Case Size: Modern classic dimensions with a versatile, everyday fit
