Key Features

• Swiss-Made H-10 Automatic Movement: At the heart of this watch lies the H-10 caliber, a high-performance automatic movement engineered in Switzerland. It delivers reliable timekeeping with a substantial 80-hour power reserve, meaning it stays accurate even if not worn for over three days—perfect for travelers or those who rotate watches.
• Bi-Directional Rotating Slide-Rule Bezel: Inspired by classic pilot watches, the outer bezel functions as a slide rule, enabling users to perform essential aviation calculations such as fuel consumption, airspeed, and distance conversions. This practical feature is intuitive for pilots and adds functional depth to the design.
• Nivachron™ Anti-Magnetic Hairspring: Hamilton incorporates Nivachron™, an advanced alloy hairspring that significantly reduces sensitivity to magnetic fields. This ensures consistent accuracy in environments with electronic interference—common in modern cockpits, offices, or urban settings.
• Sapphire Crystal with Anti-Reflective Coating: The watch face is protected by scratch-resistant sapphire crystal, known for its exceptional clarity and durability. It resists everyday wear and maintains a pristine appearance, even under direct light or harsh conditions.
• 100m Water Resistance: With a water resistance rating of 100 meters, this watch is suitable for swimming, snorkeling, and other water-related activities. It’s built to withstand splashes, rain, and brief submersion without compromising performance.
• 42mm Stainless Steel Case with Black Dial: The robust yet elegant case is crafted from polished stainless steel, offering a balanced presence on the wrist. The black dial features clear, legible markers and hands, enhanced by luminous accents for visibility in low-light conditions.
• Genuine Cow Leather Strap: The strap is made from high-quality cow leather, providing comfort and a classic look that ages gracefully. Its durable construction ensures long-term wear, while the buckle closure offers secure and adjustable fit.
