Quick TakeThere's a certain honesty to the Jazzmaster Open Heart. It doesn't shout for attention, yet it confidently bares its soul for anyone who cares to look closer. The silver dial isn't just a face; it's a stage where gears turn and jewels pivot in a constant, hypnotic performance. Watching the balance wheel oscillate through the artful cutouts is a reminder that intricate, old-world mechanics can feel perfectly at home in a modern design. This is a watch for the quietly curious, the individual who finds beauty in how things work. With an impressive 80-hour power reserve, it's a dependable partner that doesn't demand constant attention, ready to go even after a weekend on the nightstand. The smooth stainless steel case and rich brown leather strap make it a versatile classic, but the partial skeleton dial is a wink that says there's much more here than meets the eye.

DescriptionThe Hamilton Jazzmaster Open Heart, reference H32675551, is engineered 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-reflection coating to ensure maximum legibility under various lighting conditions. The silver dial is distinguished by its signature open-heart design, featuring strategic cutouts that reveal components of the mechanical movement beneath. The case construction provides water resistance up to 5 bar, equivalent to 50 meters or 164 feet, making it suitable for daily wear and resistant to splashes. An open case back further enhances the view of the internal mechanism. The lugs are spaced 20mm apart to accommodate the strap.

Powering the timepiece is the Caliber H-10, an automatic three-hand movement. This caliber provides a substantial power reserve of 80 hours, a significant extension over standard automatic movements. The integration of a Nivachron balance spring offers advanced resistance to magnetic fields and temperature fluctuations, contributing to the watch's chronometric stability and reliability. The movement's intricate snail and pearled pattern decorations are visible through both the dial-side apertures and the transparent case back. The watch is fitted with a brown calf leather strap, reference H6000001731, which fastens with a stainless steel pin buckle. The buckle width is specified at 18mm, tapering from the 20mm lug width for a comfortable fit.
