Quick TakeThere’s a certain confidence that comes with wearing a watch like the Hamilton Jazzmaster Auto H42535140. It’s not about shouting for attention; it's about a quiet, assured style. The way the light catches the textured center of the blue dial, framed by those classic Roman numerals, feels both timeless and contemporary. The 40mm stainless steel case has a satisfying heft without being cumbersome, a perfect daily driver that transitions from the office to a weekend getaway without missing a beat. And that’s the real beauty of it—knowing that the sophisticated exterior houses the robust H-10 automatic caliber. With an incredible 80-hour power reserve, this watch works through the weekend even if you don’t. It’s a piece that combines thoughtful design with serious mechanical capability, creating a companion that’s as reliable as it is handsome.

DescriptionThe Hamilton Jazzmaster, reference H42535140, is engineered with a 40mm diameter stainless steel case, providing a substantial yet classically proportioned wrist presence. A total thickness of 11.05mm ensures a streamlined profile, while the 20mm lug width accommodates the designated bracelet or alternative strap options. Protection for the dial is afforded by a sapphire crystal, selected for its high resistance to scratching and its exceptional clarity under various lighting conditions. The case is rated for water resistance up to 5 bar, which translates to a depth of 50 meters or a pressure of 73 psi, making it resilient against everyday encounters with moisture. This specific reference is classified as a past collection item.

Powering the timepiece is the Caliber H-10, an automatic three-hand movement. A key technical feature of this caliber is its impressive 80-hour power reserve, allowing for more than three full days of autonomous operation without winding. The movement's design for American Classic models, such as this Jazzmaster, includes elaborate decorative elements like snail and pearled patterns. The watch's dial is presented in a deep blue, featuring applied Roman numerals for hour markers. Its accompanying stainless steel bracelet, reference H6054251001, is secured with a folding clasp and features a buckle width of 18mm, tapering from the lugs for enhanced comfort.
