Quick TakeThere's an undeniable honesty to a watch that shows you its heart. The Jazzmaster Open Heart isn't just telling you the time; it's sharing the secret of how time is kept. The dial isn't merely a backdrop but a stage for the main performance: the steady, rhythmic pulse of the H-10 movement. Those carefully executed cutouts are windows into a world of gears and jewels, a constant, mesmerizing dance. You catch yourself staring, not to check the hour, but to appreciate the life within. It’s a piece of kinetic sculpture for the wrist. The cool, industrial grey of the dial and the polished steel case create a perfect contrast with the warm, textured ostrich leather strap. It feels both modern and timeless, a conversation starter that says you appreciate not just style, but the substance and intricate engineering that lie just beneath the surface. With an 80-hour power reserve, it's a reliable partner that’s ready to go even after a few days of rest.

DescriptionThe Hamilton Jazzmaster, reference H32565585, is presented with a case constructed from stainless steel, measuring 40mm in diameter with a thickness of 10.8mm. Its architecture features an open case back, providing an ancillary view of the internal mechanism, and is rated for water resistance up to 5 bar, which is equivalent to 50 meters or 73 psi. The dial, rendered in a distinct grey, is protected by a sapphire crystal, a material selected for its high resistance to scratching. Key apertures on the dial face reveal components of the movement, a design signature of the Open Heart series. For low-light visibility, Super-LumiNova is applied to critical elements of the display. The lugs are machined to a width of 20mm to accommodate the strap assembly.

At the core of this timepiece operates the Caliber H-10, an automatic, self-winding three-hand movement. This caliber is engineered to provide a substantial power reserve of 80 hours, significantly exceeding industry standards. The movement’s design incorporates intricate decorative patterns, specifically contrasting snail and pearled finishes, which are visible through the dial cutouts and the exhibition case back. The watch is affixed to the wrist via an ostrich leather strap (reference H6003251191), which terminates in a stainless steel folding clasp. The buckle width is specified at 18mm, ensuring a secure and streamlined fit.
