Quick TakeThere's a captivating honesty to the Jazzmaster Open Heart that you can't help but admire. It doesn't hide its intricate workings behind a solid dial; instead, it celebrates them. That striking sunray blue face is deliberately cut away, creating a window into the very essence of timekeeping. You find yourself getting lost watching the rhythmic pulse of the balance wheel and the quiet, determined sweep of the gears of the H-10 movement. It's a constant, visual reminder of the incredible Swiss craftsmanship ticking away on your wrist. With an impressive 80-hour power reserve, this watch is more than ready for a long weekend, acting as a dependable companion that won't miss a beat. Wearing this piece feels less like simply telling time and more like carrying a piece of kinetic art, a perfect fusion of classic design and transparent mechanical genius for those who appreciate seeing how things work.

DescriptionThe Hamilton Jazzmaster Open Heart, reference H32675140, is constructed with a 40mm stainless steel case that possesses a measured thickness of 11.05mm. Its assembly is engineered to guarantee water resistance rated to 5 bar, which corresponds to a depth of 50 meters or a pressure of 73 psi. The primary dial interface is a deep blue, shielded by a durable sapphire crystal that has been treated with an anti-reflective coating to ensure maximum legibility by mitigating glare. An open case back provides a transparent aperture for viewing the mechanical movement within. The case incorporates a 20mm lug width and is integrated with a stainless steel bracelet, identified by strap reference H6054251001.

Central to this timepiece's function is the Hamilton Caliber H-10, an automatic movement featuring a three-hand display. This caliber is distinguished by its substantial 80-hour power reserve, offering extended operational autonomy. A critical technological feature is the inclusion of a Nivachron balance spring, an advanced alloy that delivers heightened resistance to magnetic fields, shock, and temperature variations, which contributes to more stable and reliable chronometry. The movement is finished with intricate contrasting snail and pearled patterns, visible through the dial apertures and the exhibition case back. The bracelet is secured with a folding clasp that has a buckle width of 18mm, ensuring a firm fit.
