Key Features

• NH35 Automatic Movement: Sourced from Japan, this self-winding mechanical movement offers 41 hours of energy storage, ensuring reliable timekeeping without manual winding under normal use. It’s known for its durability and accuracy, making it a favorite among tool watch enthusiasts.
• 200M Water Resistance: Rated for depths up to 200 meters (20 ATM), this watch is suitable for recreational diving, snorkeling, swimming, and water sports. The screw-down crown and case back enhance sealing to prevent water ingress.
• Ceramic Unidirectional Bezel: The 120-click rotating bezel is crafted from scratch-resistant ceramic and turns only counterclockwise, a critical safety feature for tracking elapsed dive time. Its precise clicks provide tactile feedback and prevent accidental movement.
• Super Luminous Display: Equipped with C3 green and BGW9 blue luminous material on the hands and markers, the watch offers exceptional visibility in dark or underwater environments. The dual-color lume adds a distinctive visual element while maintaining functional clarity.
• Sapphire Crystal with AR Coating: The watch face is protected by synthetic sapphire crystal, one of the hardest materials used in watchmaking, offering superior scratch resistance. The anti-reflective coating reduces glare for improved readability in bright conditions.
• 316L Stainless Steel Construction: Both the case and case back are made from 316L surgical-grade stainless steel, known for its corrosion resistance, strength, and hypoallergenic properties. This ensures long-term durability and a polished, professional appearance.
• Screw-Down Crown and Case Back: These features ensure a secure seal, contributing to the watch’s water resistance and protecting the internal movement from dust and moisture.
