Quick TakeThere's a certain magic to a watch that isn't afraid to show its inner workings, and this Jazzmaster Open Heart is a master of the reveal. The rich, wine-like burgundy of the dial creates a dramatic stage for the main event: the peek-a-boo performance of the escapement and balance wheel doing their tireless dance. It’s a constant, beautiful reminder of the living machine you've chosen to wear. This isn't just a timepiece; it's an experience. With the robust H-10 movement, you get a class-leading 80 hours of power reserve, meaning this watch keeps ticking through a long weekend even if you give it a rest. It blends traditional Swiss watchmaking, evident in the decorative patterns on the movement, with a confidently modern aesthetic. The stainless steel bracelet feels solid and refined, making it versatile enough for the boardroom or a weekend getaway. It’s a piece for someone who values substance and mechanics as much as style.

DescriptionThe Hamilton Jazzmaster Open Heart, designated by reference number H32675170, is encased in a stainless steel housing that measures 40mm in diameter and has a thickness of 11.05mm. Its structural integrity provides water resistance rated to 5 bar, which corresponds to a depth of 50 meters or a pressure of 73 pounds per square inch. Protecting the dial is a scratch-resistant sapphire crystal that features an anti-reflective coating to ensure optimal clarity and reduce glare. The timepiece incorporates an exhibition-style open case back, offering a secondary view of the intricate mechanics within. For strap and bracelet integration, the case is engineered with a standard 20mm lug width, accommodating the factory-supplied stainless steel bracelet.

Powering the watch is the Caliber H-10, an automatic, self-winding mechanical movement. This three-hand engine delivers a superior power reserve of 80 hours, significantly exceeding industry standards. Precision is enhanced by the inclusion of a Nivachron balance spring, a modern alloy valued for its formidable resistance to magnetism, temperature fluctuations, and shock, which contributes to more stable and reliable timekeeping. Visible through both the dial apertures and the sapphire case back, the H-10 movement is adorned with detailed snail and pearled patterns. The accompanying stainless steel bracelet, reference H6054251001, is secured by a folding clasp with an 18mm buckle width, ensuring a seamless and secure fit on the wrist.
