Quick TakeThere's a certain confidence in showing your cards, and the Jazzmaster Open Heart lays everything on the table. That deep burgundy dial isn't just a color; it's a stage for the mechanical ballet happening underneath. The cutouts are unapologetic, slicing away tradition to give you a front-row seat to the pulsing balance wheel and the intricate dance of the escapement. It’s a watch with a dual personality. From a distance, it's the sophisticated Jazzmaster, with its clean lines and classic proportions. But up close, it’s a modern marvel, a piece of kinetic art. The robust 80-hour power reserve isn't just a spec—it’s freedom. It means this watch works with your life, ready to go even if you give it a rest for the weekend. It’s for the person who respects heritage but isn’t bound by it, someone who finds beauty in the complexity of how things work and isn't afraid to put it on full display.

DescriptionThe timepiece is constructed with a stainless steel case measuring 40mm in diameter and a thickness of 11.05mm. Its front is protected by a sapphire crystal, which incorporates an anti-reflective coating to ensure maximum legibility under various lighting conditions. The exhibition-style open case back provides a view of the internal mechanism. This watch maintains water resistance up to 5 bar, equivalent to a depth of 50 meters or 73 psi, making it suitable for daily wear and resistant to incidental water contact. The lugs are spaced at a width of 20mm to accommodate the strap.

Powering the watch is the Hamilton Caliber H-10, an automatic three-hand movement. This caliber is notable for its substantial 80-hour power reserve, a feature enabled by advanced engineering. The movement incorporates a Nivachron balance spring, which offers enhanced resistance to magnetic fields and temperature variations, thereby improving chronometric stability. The movement's architecture is visible through the dial's signature open-heart cutouts. The accompanying strap, reference H6003261211, is crafted from calf leather and secures to the wrist with a stainless steel pin buckle, which has a width of 18mm.
