Quick TakeDon't let the distinguished, almost statesman-like appearance fool you; the Spirit of Liberty is a machine with a rebellious heart. It's a watch that seems to understand the long game. On the surface, you see a crisp silver dial with elegant hands and a classic case profile that works anywhere from the boardroom to a weekend retreat. But the secret, laser-engraved on the rich calf leather, whispers a powerful truth. Underneath that sapphire crystal beats the H-10 caliber, a modern marvel that stockpiles an impressive 80 hours of power. That’s more than three full days of autonomy, of freedom from the daily ritual of winding. It’s a quiet declaration of independence for your wrist. This isn't just a device for telling time; it's a companion piece for a life lived deliberately, blending old-world American charm with the steadfast, relentless precision of contemporary Swiss engineering. It’s a conversation starter that says you value both heritage and performance.

DescriptionThe Hamilton American Classic Spirit of Liberty, reference H42415551, is housed in a 42mm stainless steel case with a measured thickness of 11.4mm. Its architecture includes a 22mm lug width, facilitating a secure connection to the strap assembly. The dial is protected by a scratch-resistant sapphire crystal, which has been treated with an anti-reflective coating to ensure maximum legibility under various lighting conditions. A silver dial serves as the backdrop for the time display, complemented by a date aperture positioned at the 6 o'clock mark. The watch's construction provides water resistance rated to 5 bar, equivalent to 50 meters or 73 psi, making it resilient against incidental water exposure. An open case back is integrated into the design, offering a direct view of the internal mechanical movement and its detailed finishing.

At the core of the timepiece is the Hamilton Caliber H-10, an automatic, self-winding movement. This three-hand caliber provides a substantial power reserve of 80 hours, a significant extension over standard automatic movements. For American Classic models such as this one, the H-10 is distinguished by its intricate finishing, which includes contrasting snail and pearled patterns visible through the exhibition case back. The watch is secured to the wrist by a calf leather strap, identified by reference H6003241151. This strap terminates in a stainless steel folding clasp, which has a buckle width of 20mm, providing both security and ease of use for the wearer.
