Quick TakeThere's a certain magic in a watch that lets you peek behind the curtain, and the Jazzmaster Open Heart is the ultimate backstage pass. It ditches the straight-laced formality of a solid dial for a tantalizing glimpse into its mechanical soul. You find yourself watching the hypnotic pulse of the balance wheel, a tiny, living machine working tirelessly on your wrist. The 80-hour power reserve is no small feat; it’s the watch telling you it's got the stamina to keep up with your longest weekends, no questions asked. Encased in a confident 40mm of stainless steel, it has a presence that is both modern and timeless, while the complex grey dial serves as the perfect industrial stage for the performance within. It’s a conversation starter that doesn’t shout, but rather invites a closer look, rewarding the curious with a view of the beautiful complexity that makes a mechanical watch so compelling.

DescriptionThe Hamilton Jazzmaster Open Heart, bearing the reference number H32565185, is constructed from a stainless steel case measuring 40mm in diameter with a total thickness of 10.8mm. The case architecture provides a water resistance rating of 5 bar, equivalent to 50 meters or 73 pounds per square inch, and is sealed by a sapphire crystal on the front and an exhibition-style open case back on the rear. It accommodates a lug width of 20mm for the attachment of its corresponding stainless steel bracelet (reference H6053251001), which terminates in a 20mm folding clasp. The grey dial features strategic apertures that reveal the movement within and is treated with Super-LumiNova for enhanced legibility in low-light environments.

Powering the timepiece is the Caliber H-10, an automatic three-hand movement. This mechanical system is engineered to provide a substantial power reserve of 80 hours, negating the need for frequent winding. The H-10 is specifically decorated for its application in the American Classic series, exhibiting intricate contrasting snail and pearled patterns on its components. These finishing details are observable through both the dial-side cutouts and the sapphire case back. The movement's function is strictly time-telling, with hours, minutes, and seconds, omitting a date complication to maintain the dial's visual balance and focus on the open-heart design.
