Whether you’re drawn to the romance of flight, appreciate mechanical watchmaking, or simply want a versatile timepiece that transitions seamlessly from boardroom to weekend adventure, this watch delivers enduring style and dependable performance.

Key Features

• Swiss-Made Automatic Movement – At the heart of this watch is a self-winding mechanical movement crafted in Switzerland, a hallmark of precision and tradition. Unlike quartz watches, it doesn’t require a battery; instead, it harnesses energy from the natural motion of your wrist to keep accurate time. This not only enhances longevity but also connects the wearer to centuries of horological expertise.
• 42mm Stainless Steel Case – The case strikes an ideal balance between presence and wearability. Large enough to make a statement, yet proportioned to sit comfortably on a variety of wrist sizes, it embodies a masculine yet refined silhouette that suits both casual and formal occasions.
• Sapphire Crystal – The watch face is shielded by sapphire crystal, one of the hardest transparent materials available. This ensures exceptional resistance to scratches and maintains optical clarity over years of use, keeping the dial looking pristine even with daily exposure to keys, desks, and other common surfaces.
• Black Dial with Analog Display – The high-contrast black dial features luminous hour markers and hands, allowing for clear time reading in low-light environments. Its clean, functional layout reflects classic aviation instrument design, emphasizing legibility and purpose—a nod to the cockpit gauges that inspired it.
• 100m Water Resistance – With a water resistance rating of 100 meters (10 ATM), this watch is built to handle swimming, snorkeling, and everyday exposure to water such as handwashing or rain. It is not suitable for scuba diving or high-impact water sports, but it offers peace of mind during most aquatic activities.
• Stainless Steel Bracelet – The integrated stainless steel strap is designed for both comfort and durability. Its polished and brushed finishes complement the case, while the secure closure ensures a stable fit throughout the day. The bracelet’s robust construction resists corrosion and maintains its luster over time.
