Quick TakeThere's a certain magic to a watch that isn't afraid to show its hand. The Jazzmaster Open Heart lays its cards on the table, or rather, on the dial. That rich, forest green expanse isn't just a backdrop; it's a curtain pulled back on a mesmerizing mechanical performance. Through the carefully executed cutouts, you get a front-row seat to the steady, hypnotic pulse of the escapement and the intricate dance of the gear train. It transforms the simple act of checking the time into a moment of genuine connection with the craft of watchmaking. The H-10 movement, with its impressive 80-hour power reserve, isn't just a workhorse; it's a beautifully decorated engine that you're invited to admire. Paired with a supple brown leather strap, it strikes the perfect balance between intellectual curiosity and everyday wearability. This is the watch for someone who finds beauty in how things work and wants a constant, elegant reminder on their wrist.

DescriptionThe Hamilton Jazzmaster Open Heart, with the reference number H32675560, is constructed with a 40mm stainless steel case that possesses a total thickness of 11.05mm. For optimal dial clarity under various lighting conditions, the primary interface is a sapphire crystal enhanced with an anti-reflection coating. This durable crystal protects a green dial, which is distinguished by its unique open-heart apertures. The case architecture provides a lug width of 20mm and includes an exhibition-style open case back, offering a secondary view of the movement. This model is certified for water resistance up to 5 bar, equivalent to a depth of 50 meters or a pressure of 73 psi, ensuring resilience against everyday splashes. Fastening the watch is a cow leather strap (reference H6003261211) that integrates a traditional pin buckle clasp, tapering to a buckle width of 18mm.

Powering the H32675560 is the Hamilton Caliber H-10, a self-winding automatic movement. A key feature of this caliber is its extended 80-hour power reserve, which provides reliable timekeeping for over three days without winding. The movement's precision is further fortified by the integration of a Nivachron balance spring, which offers exceptional resistance to the effects of magnetic fields, temperature fluctuations, and physical shocks. As is characteristic for the American Classic series, the visible components of the H-10 movement are finished with intricate and contrasting snail and pearled patterns. These decorative elements are deliberately showcased through the dial-side cutouts and the transparent case back, forming the central design principle of the Open Heart model.
