Quick TakeThis Jazzmaster Open Heart is less of a time-teller and more of a conversation piece that just happens to be exceptionally good at its job. It's for the person who appreciates that the true beauty of a machine lies in its function. Hamilton's designers knew this and, instead of hiding the magic, they carved away the silver dial to put the beating heart of the Caliber H-10 on full display. You get to watch the escapement and balance wheel perform their constant, mesmerizing dance. It’s a confident design choice, backed by serious substance like the massive 80-hour power reserve. You could take it off Friday evening and find it still ticking accurately on Monday morning. The polished and brushed finishes on the 40mm steel case catch the light perfectly, making it a versatile piece that feels just as right with a casual shirt as it does under a suit cuff. It’s a statement of sophisticated curiosity.

DescriptionThe Hamilton Jazzmaster, reference H32565121, is engineered with a 40mm case constructed from stainless steel, featuring a total thickness of 10.8mm. Its front is protected by a sapphire crystal, renowned for its scratch resistance, ensuring a clear view of the silver dial. The case architecture provides water resistance up to 5 bar, which is equivalent to 50 meters or 164 feet, suitable for everyday exposure to moisture. An open case back, also fitted with a crystal, allows for an additional view of the internal mechanism. The lugs are machined to a width of 20mm to accommodate the integrated stainless steel bracelet.

Powering the timepiece is the Caliber H-10 automatic movement, a three-hand mechanical unit. This caliber is notable for its extended power reserve of 80 hours, a significant increase over standard automatic movements. The movement's design incorporates intricate contrasting snail and pearled patterns, visible through the dial's signature apertures and the transparent case back. The stainless steel strap, reference H6053251001, is secured to the wrist with a butterfly-style buckle. The buckle width is specified at 20mm, matching the lug width for a seamless and robust integration with the watch case.
