Key Features

• Japan NH35 Automatic Movement: A trusted mechanical caliber celebrated for its accuracy, reliability, and low maintenance. The self-winding mechanism keeps time precisely as you move throughout the day or night.
• Sapphire Crystal Glass with Blue Light AG Coating: Exceptionally scratch-resistant and anti-reflective, this premium glass protects the dial while ensuring clear visibility in bright sunlight or low-light conditions.
• Ceramic Bezel with 12 O’clock Luminous Marker: Durable and fade-resistant, the ceramic bezel includes a glow-in-the-dark marker for easy orientation during nighttime activities or in dark environments.
• Luminous Hands and Markers (BGW-X1/C3): High-performance luminescent material on both hour markers and snowflake-style hands allows instant legibility without external light sources—ideal for early mornings, late nights, or subterranean settings.
• Screw-down Crown and Case Back: Dual sealing mechanisms provide superior protection against water ingress, supporting the 200-meter waterproof rating essential for diving, swimming, and wet-weather exposure.
• 316L Stainless Steel Bracelet & Folding Clasp: Crafted from marine-grade stainless steel, the bracelet resists corrosion and tarnishing. The secure folding clasp features a safety lock and signature San Martin hexagon logo.
• Hexagon Logo Details: Authentic branding appears on the crown (3D engraved), case back, and clasp—a hallmark of San Martin’s commitment to quality and craftsmanship.
• Vibrant Dial Finishes: Choose from four distinct dial colors—matte black, matte blue, matte green, and enamel light green—each enhanced with an applied hexagon logo and unique luminous hand styling for visual distinction and personal expression.

Benefits & Use Cases

Engineered for versatility, this watch excels across multiple environments. Its 200-meter water resistance makes it suitable not only for swimming and snorkeling but also for shallow recreational diving, giving users confidence in wet conditions. The automatic movement eliminates the need for battery replacements, making it ideal for frequent travelers or professionals who value convenience and reliability. The 40mm case diameter fits comfortably on most wrists without appearing bulky, seamlessly transitioning from business casual attire to outdoor gear. Whether navigating a dimly lit subway car, checking the time during an early morning run, or monitoring depth during a dive, the luminous hands and markers ensure instant readability in any setting.

The solid 316L stainless steel construction resists scratches, rust, and everyday wear, maintaining its polished look over years of use. The screw-down crown and case back create a hermetic seal that protects internal components, extending the life of the NH35 movement. Meanwhile, the ceramic bezel adds scratch resistance and retains its color and clarity far longer than traditional aluminum counterparts.

With seven customer reviews averaging 4.5 stars and a ranking among top-selling men’s wristwatches, this model reflects strong community approval. While the included bracelet suits most preferences, the pin-locking structure allows for easy strap swaps if desired. As an authentic product from 1963 Watch under the San Martin brand, it embodies tool-watch functionality with modern refinements—making it a practical yet stylish choice for discerning buyers.
