Quick TakeThere's a certain magic in being able to see the beating heart of your watch, and the Jazzmaster Open Heart delivers that experience with theatrical flair. Instead of hiding its secrets, it puts the mesmerizing dance of the escapement and balance wheel on full display right on the dial. This isn't just a time-telling device; it's a piece of kinetic art for your wrist. The reliable H-10 movement provides an impressive 80-hour power reserve, meaning this performer can keep ticking through a long weekend adventure without missing a beat. The 40mm stainless steel case strikes a perfect balance between presence and comfort, making it a versatile companion for any occasion. It’s a watch for someone who appreciates not just the 'what' of telling time, but the 'how'. It’s a constant, beautiful reminder of the intricate Swiss engineering that makes it all possible, presented with a modern, confident edge.

DescriptionThe Hamilton Jazzmaster Open Heart, designated by reference number H32565135, is constructed around a 40mm stainless steel case that measures 10.8mm in thickness. This case is engineered for durability and aesthetic appeal, featuring a 20mm lug width that accommodates the integrated bracelet. The dial is protected by a sapphire crystal, renowned for its high resistance to scratching, ensuring a clear view of the dial and its signature aperture. An open case back is also incorporated into the design, offering an unobstructed view of the movement from the rear. The timepiece maintains water resistance up to 5 bar, which corresponds to a depth of 50 meters or 164 feet, providing protection against incidental water contact.

Powering the watch is the Caliber H-10, an automatic, self-winding mechanical movement. A key technical attribute of this caliber is its substantial 80-hour power reserve, which allows for continuous operation for more than three days when fully wound. The movement's architecture, including its intricate contrasting snail and pearled patterns, is partially visible through the "open heart" cutaway on the black dial. For optimal readability in various lighting scenarios, the hands and indices are treated with Super Luminova. The watch is completed with a stainless steel bracelet (strap reference H6053251001), which is fastened by a secure folding clasp.
