Key Features
- Bi-Directional Rotating Slide-Rule Bezel: Allows for quick in-flight calculations, including fuel consumption, airspeed, and unit conversions—essential for pilots and travelers who need reliable metrics at a glance. This practical tool transforms the watch into more than an accessory, offering real-world functionality for aviation professionals and enthusiasts alike.
- Swiss-Made H-21-Si Automatic Movement: Powered by a high-performance caliber with a silicon hairspring, this movement enhances accuracy, resists magnetism, and requires no battery—keeping perfect time through self-winding mechanics. The absence of batteries means lower long-term maintenance and consistent performance, making it a dependable choice for daily wear.
- 44mm Stainless Steel Case: Offers a bold, masculine profile that stands out on the wrist while maintaining durability and resistance to daily wear and tear. The substantial case size ensures excellent legibility and a confident presence, suitable for larger wrists or those who prefer a commanding timepiece.
- Sapphire Crystal: Provides exceptional scratch resistance, ensuring the dial remains clear and unblemished even after prolonged use. This premium material protects against the minor scrapes and impacts of everyday life, preserving the watch’s appearance over time.
- 100m Water Resistance: Suitable for swimming, snorkeling, and water sports, making it a versatile companion for both land and aquatic activities. This level of protection means you can wear it while washing hands, caught in the rain, or enjoying water-based recreation without concern.
- Blue Dial with Analog Display: Features a clean, legible layout with luminous markers and hands for visibility in low-light conditions, reinforcing its aviation heritage. The deep blue hue mirrors the clarity of open skies, while the analog format ensures easy, intuitive reading at a glance.
- Brown Cow Leather Strap: Combines comfort and classic style, offering a secure fit with a refined look that transitions easily from casual to formal settings. The leather develops a unique patina over time, adding character and personalization with each wear.

The slide-rule bezel makes it a practical tool for calculating critical flight data, such as fuel burn rates and ground speed, directly from the wrist—eliminating the need for additional devices during flight planning. Its robust construction ensures it holds up under demanding conditions, from cockpit environments to urban commutes. The 100m water resistance allows for worry-free use during water-based activities like swimming or snorkeling, while the sapphire crystal protects against scratches in daily wear. The combination of a stainless steel case and leather strap gives it a versatile aesthetic—equally at home in a boardroom or at a weekend airfield gathering. Thanks to its automatic movement, it maintains accuracy without needing a battery, relying instead on the natural motion of the wearer to stay powered. This self-sustaining mechanism reduces long-term maintenance and supports reliable timekeeping over years of use.
