San Martin SN0111 40mm Diver Watch – NH35 Automatic, Sapphire, 300M
The San Martin SN0111 represents everything enthusiasts love about modern microbrand dive watches: outstanding finishing, premium materials, dependable Japanese mechanics, and a clean aesthetic inspired by tool-watch heritage rather than hype.
At 40mm with a wrist-friendly 47.5mm lug-to-lug, the SN0111 delivers that perfect everyday diver fit — substantial, but never bulky. The case is fully crafted from 316L stainless steel, combining brushed surfaces with polished accents for a balanced, premium look.
Up front, you get a sapphire crystal with internal AR coating, ensuring exceptional clarity in all lighting conditions. The unidirectional ceramic bezel offers a confident, tactile click with a luminous pip at 12 for precise timing underwater or during daily tasks.
The dial is available in two timeless colors — deep navy blue and classic black — each featuring San Martin’s modern applied indices and the recognizable snowflake hands. Everything is coated with Swiss BGW-9 lume, producing a crisp blue glow that lasts through the night.
Inside sits the Seiko NH35 automatic movement, a proven workhorse known for durability, easy servicing, and accuracy. The 300M water resistance, along with a screw-down crown and screw-down case back, gives the SN0111 genuine dive capability.
The bracelet is a solid 316L stainless steel unit with female end links for better wrist drape, and it includes San Martin’s newest fly-adjustable clasp — making tool-free micro-adjustments possible on the go.
Overall, the SN0111 is a complete package: rugged, refined, and ready for anything. It’s a watch built to last decades, offering premium specifications at a tremendous value.

Top picks just for you
Absolutely unbeatable for this price. On first impression, it can compete with significantly more expensive watches from European and international brands that cost three to five times as much. It feels exceptionally comfortable on the wrist, and the movement makes a very good impression. Only the links of the bracelet could be more substantial and the screws of the connections could be more precise. For my taste.
