Quick TakeIt's one thing to be told a watch has a soul, but it's another thing entirely to see it. The Jazzmaster Open Heart doesn't just tell you the time; it shows you time being made. The silver dial isn't merely a backdrop for the blued hands; it's a stage, and the star of the show is the escapement, ticking and turning for all to see. It’s like having a secret window into the intricate, living world of micro-mechanics strapped to your wrist. This isn’t a sterile piece of equipment. You can feel the energy from the 80-hour power reserve, knowing it will keep running strong all weekend long without a single thought. The open-heart design is a bold statement, a nod to those who appreciate not just the what, but the how. It’s a conversation starter, a piece of wearable art that perfectly balances classic Swiss watchmaking tradition with a confident, modern edge.

DescriptionThis timepiece is engineered with a multi-piece stainless steel case measuring 40mm in diameter and a thickness of 11.05mm. The lug width is a standard 20mm, accommodating the integrated stainless steel bracelet. Protecting the dial is a scratch-resistant sapphire crystal, which has been treated with an anti-reflective coating to ensure maximum legibility under various lighting conditions. The case architecture provides water resistance up to 5 bar, equivalent to a depth of 50 meters or 164 feet, making it suitable for daily wear and incidental water exposure. An exhibition-style open case back, also fitted with sapphire crystal, allows for a secondary view of the internal mechanism, complementing the primary view offered by the dial-side aperture.

At the core of the H32675150 is the Hamilton Caliber H-10, an automatic three-hand movement. This caliber is distinguished by its extended power reserve of 80 hours, a significant increase over standard automatic movements. The enhanced longevity is achieved through a refined kinetic chain and a superior mainspring. A key component of the H-10 is its Nivachron balance spring, which offers exceptional resistance to magnetic fields, temperature variations, and shocks, thereby improving the watch's overall precision and reliability. The movement's surfaces feature intricate contrasting snail and pearled patterns, visible through the dial's carefully executed cutouts. The accompanying stainless steel bracelet, reference H6054251001, features a folding clasp with a buckle width of 18mm for a secure fit.
