Quick TakeDon't let the refined appearance fool you; this Jazzmaster is a machine with a soul laid bare. It's a conversation starter that doesn't need to shout. The intricate dance of gears and springs, fully visible through the skeletonized white dial, is the main event. You find yourself tracing the path of energy from the rotor's spin to the steady beat of the Nivachron balance spring, a tiny, resilient heart that promises an 80-hour power reserve. That's a full weekend of freedom without missing a beat. The rose gold-toned hands sweep over this mechanical cityscape, a warm contrast to the cool steel of the 40mm case. Strapped to the wrist with a supple green leather band, it feels less like an accessory and more like a trusted co-conspirator for life's adventures, equally at home navigating a boardroom or a weekend road trip. It’s a watch for the person who appreciates that true substance, like the H-10-S movement, is always worth a closer look.

DescriptionThe Hamilton Jazzmaster Skeleton Auto, reference H42535810, is a meticulously engineered timepiece designed for transparency and performance. Its 40mm stainless steel case, with a measured thickness of 11.05mm, provides a robust housing for the intricate mechanics within. The dial is presented in a stark white, serving as a clean frame for the skeletonized view of the movement. A sapphire crystal, treated with an anti-reflective coating, protects the dial, ensuring maximum legibility and scratch resistance under various lighting conditions. The exhibition-style open case back further enhances the view of the caliber, secured to achieve a water resistance rating of 5 bar, equivalent to 50 meters or 73 psi. This construction safeguards the internal components from incidental water exposure.

Powering the H42535810 is the Caliber H-10-S, an automatic movement renowned for its extended 80-hour power reserve. This impressive duration is achieved through a refined kinetic chain and the inclusion of a Nivachron balance spring, which offers superior resistance to magnetic fields, temperature variations, and shocks, thereby enhancing chronometric stability. The case features a 20mm lug width, accommodating a green cow leather strap (reference H6000001721). This strap is fastened with a traditional stainless steel pin buckle, which has a width of 18mm, ensuring a secure and classic fit on the wrist. Every component is manufactured to precise tolerances, reflecting the standards of the Jazzmaster collection.
