San Martin SN021-G-B3 – Explorer Automatic Stainless Steel Watch
The San Martin SN021-G-B3 brings the legendary Explorer-style field watch into a refined 36mm format — compact, versatile, and engineered for everyday adventure. Featuring premium PT5000 or Swiss SW200 movement options, a domed sapphire crystal, BGW9 lume, and a full 316L stainless steel build, it delivers luxury-grade finishing with true tool-watch performance.
If you’re coming from the TAIGEER 38mm Explore Climbing Watch, this San Martin model is the perfect elevated alternative — with even stronger finishing, upgraded crystal, richer lume, and premium movement choices.
A Modern Classic Built for Everyday Exploration
The San Martin SN021-G-B3 distills everything enthusiasts love about field watches into a compact 36–37mm design that wears comfortably on every wrist. With its clean dial, high-contrast indices, and sapphire clarity, it’s crafted for people who demand reliability without compromising on style.
Available in rich enamel Green, matte Black, and the iconic Tiffany Blue, each dial adds its own personality while maintaining San Martin’s signature tool-watch DNA.
Premium Movements: PT5000 or Swiss SW200
Choose the movement that fits your lifestyle:
PT5000 Automatic
• High-accuracy Chinese movement
• Smooth sweep
• Hand-winding + hacking
• Excellent value & reliability
Sellita SW200 Automatic
• Swiss-made precision
• 28,800 bph smooth sweep
• Industry-standard performance
Both options deliver stable accuracy, strong durability, and long-term serviceability.
Built to Last — 316L Steel + Sapphire
The SN021-G-B3 uses full 316L stainless steel construction, giving it a solid and premium feel. The domed Top-Hat Sapphire Crystal with AR coating brings distortion-free visibility while resisting scratches far better than mineral glass.
The watch’s screw-down crown and screw-down caseback ensure dependable water resistance up to 10ATM / 100M, making it suitable for:
✔ Swimming
✔ Snorkeling
✔ Daily wear
✘ Not suitable for diving
BGW-9 Blue Lume — Night Visibility Done Right
San Martin equips this model with Swiss BGW-9 Super-LumiNova, offering an ice-blue glow that is:
✔ Bright
✔ Long-lasting
✔ Evenly applied
✔ Visible in seconds after exposure to light
The snowflake hands and applied 3D hour markers elevate legibility both day and night.
Bracelet & Fit — Comfortable For All-Day Wear
The watch comes with a solid 316L stainless steel bracelet featuring:
• 20mm tapering to 16mm
• Folding clasp with safety lock
• San Martin 3D hexagon logo
• Four micro-adjust positions
The result? A secure, tailored fit — no tools needed.
