Key Features

• All-Rounder Style: This dive watch combines a sleek, professional appearance with rugged functionality, making it suitable for both aquatic adventures and daily use. The 316L stainless steel construction provides excellent corrosion resistance and a polished finish that resists wear over time. Inspired by renowned Japanese watchmaking traditions, the design emphasizes clarity and durability. Its versatile look ensures it pairs well with casual, business, or sport attire, offering both form and function in one sophisticated package.
• Efficient Craftsmanship: At the heart of this timepiece lies the reliable Japanese Automatic NH35 movement, known for its accuracy and robust performance. This self-winding mechanism delivers a consistent 40-hour power reserve, ensuring the watch remains operational even after periods of inactivity. A convenient date window at the 3 o’clock position adds practical utility for everyday scheduling. As an automatic movement, it eliminates the need for battery replacements, offering long-term reliability and low maintenance—hallmarks of expert Italian-inspired watchmaking precision.
• Sea-Bound Anytime: Engineered for the demands of deep-sea diving, this watch boasts an impressive 200-meter water resistance rating and undergoes rigorous pressure testing to guarantee performance under extreme conditions. The unidirectional rotating bezel allows divers to safely track elapsed time underwater, a critical feature for dive safety. Protected by a scratch-resistant sapphire crystal with an anti-reflective coating, the dial remains crystal clear in bright or low-light environments. The secure diver-style clasp, featuring a fold-over lock and two-button deployment, ensures the watch stays firmly in place during vigorous activity.
