Designed for divers, adventurers, and outdoor enthusiasts, this watch combines rugged construction with precision engineering to deliver reliable performance in demanding environments. At its core is the trusted NH35 automatic movement, known for its accuracy and low maintenance. The watch features a sapphire crystal face for superior scratch resistance and a luminous “Sea Ghost” dial that ensures visibility in low-light and deep-water conditions. With a 300-meter water resistance rating, it meets the standards of a true ISO-compliant dive watch, making it suitable for recreational and professional diving alike.

STEELDIVE has built a reputation for crafting timepieces that withstand the rigors of extreme environments. With a focus on using the finest materials, their watches have become the preferred choice for adventurers, divers, and outdoor enthusiasts. Each model undergoes rigorous testing to ensure it performs reliably under pressure—whether submerged in ocean depths or exposed to harsh weather conditions. The SD1957 is a testament to this commitment, blending functional design with robust engineering.

Key Features

• NH35 Automatic Movement: Powered by the reliable Seiko NH35 caliber, this self-winding movement delivers consistent timekeeping without the need for a battery. It features manual winding capability and a 41-hour power reserve, ensuring the watch keeps running even if not worn daily. This movement is widely respected in the watch community for its durability and precision, making it a trusted choice for dive watches.
• 300M Water Resistance: Engineered to withstand depths of up to 300 meters (990 feet), this watch is suitable for recreational scuba diving, snorkeling, and water sports. The screw-down crown and case back enhance sealing integrity under pressure, preventing water ingress during deep dives. This level of protection meets professional diving standards, giving users confidence in its performance underwater.
• Sapphire Crystal: The watch face is protected by a sapphire crystal, one of the hardest transparent materials available. This ensures exceptional resistance to scratches from sand, metal, and daily wear, maintaining clarity over time. Unlike mineral or acrylic crystals, sapphire retains its finish even after prolonged exposure to abrasive elements, making it ideal for active lifestyles.
• Luminous “Sea Ghost” Display: The dial and hands are coated with high-intensity luminous material that absorbs light and glows brightly in the dark. This feature is essential for underwater visibility and nighttime readability. Whether navigating a reef at dusk or checking time during a night dive, the glowing display ensures you stay informed without needing external light sources.
• Unidirectional Rotating Bezel: The 60-minute graduated bezel allows divers to track elapsed time underwater safely. Its unidirectional design prevents accidental movement that could lead to miscalculations during a dive. This critical safety feature ensures that if the bezel is knocked, it can only move in a direction that reduces the indicated dive time, alerting the diver to potential risk.
• Stainless Steel Construction: The case and bracelet are crafted from corrosion-resistant stainless steel, offering durability and a polished, professional appearance that transitions well from dive site to daily wear. The material resists tarnishing and maintains its finish even in saltwater environments, ensuring long-term wearability.

Important Notes

Please note that while this watch is built for diving, it should be rinsed with fresh water after exposure to saltwater to maintain optimal condition. This helps prevent corrosion and buildup that could affect performance over time. Avoid pressing buttons or operating the crown while submerged unless specifically rated for such use—this model features a screw-down crown designed for sealing, not underwater manipulation.

The watch comes in original packaging with dimensions of 6.77 x 4.84 x 2.44 inches and weighs 9.91 ounces. Warranty information is available through the manufacturer’s support page. This product was first made available on November 10, 2023, and is listed under ASIN B0CN2VVHT8. Always refer to official guidelines for maintenance and care to ensure longevity. Regular servicing by a qualified technician is recommended every few years to preserve water resistance and movement accuracy.
