Key Features

• Swiss Automatic Movement: The watch is powered by a precise 3-hand Swiss automatic movement, eliminating the need for a battery. This self-winding mechanism relies on the natural motion of the wearer’s wrist to keep time, embodying the essence of traditional horology. The movement is visible through the open-heart dial, showcasing the intricate mechanics that drive the timepiece—a true nod to mechanical artistry and engineering excellence.
• Open Heart Dial Design: The blue dial features a distinctive open-heart aperture at the 12 o’clock position, offering a captivating view of the oscillating rotor and gear train. This design element not only enhances visual appeal but also reflects Hamilton’s commitment to transparency and mechanical craftsmanship. The interplay of light across the exposed components creates a dynamic display that changes with every movement of the wrist.
• Durable Sapphire Crystal: The watch face is protected by scratch-resistant sapphire crystal, ensuring long-term clarity and resistance to everyday wear and tear. This premium material is second only to diamond in hardness, making it highly resistant to scratches from keys, screens, and other common surfaces. It maintains the watch’s pristine appearance even after years of regular use.
• 42mm Stainless Steel Case: The robust yet refined case is crafted from high-quality stainless steel, providing excellent corrosion resistance and a polished, professional look suitable for both casual and formal settings. The 42mm diameter strikes a balance between presence and wearability, making it ideal for men with medium to larger wrists who appreciate a substantial yet comfortable timepiece.
• 50m Water Resistance: With a water resistance rating of 50 meters, the watch can withstand splashes, rain, and brief immersion in water, making it suitable for everyday activities like handwashing and light swimming. It is not intended for diving, snorkeling, or high-impact water sports, but it provides peace of mind during daily routines involving water exposure.
• Genuine Calf Leather Strap: The watch is fitted with a supple calf leather strap that offers comfort and a classic appearance. Over time, the leather develops a unique patina, enhancing its character and personal connection to the wearer. The strap is designed for all-day comfort, with a secure buckle closure that ensures a snug and reliable fit.
