Quick TakeThis Intra-Matic isn't just a watch; it's a feeling, a nod to an era when design had soul. It channels the clean, confident aesthetic of the 60s but with guts that are purely contemporary. That rich, sunburst blue dial paired with the warm, textured brown leather is a timeless combination that just works, effortlessly bridging the gap between a tailored suit and a casual weekend. You get the vintage vibe without any of the reliability headaches. Tucked inside that perfectly proportioned 40mm steel case is the H-10 movement, a mechanical powerhouse that gives you an incredible 80-hour power reserve. Set it down on Friday, and it’s ready to go on Monday without a single wind. It’s the kind of watch that doesn’t demand attention but quietly earns respect with its blend of classic looks and modern mechanical engineering.

DescriptionThe Hamilton American Classic Intra-Matic, reference H38425540, is constructed around a stainless steel case measuring 40mm in diameter with a thickness of 10.95mm. Its front is sealed by a sapphire crystal, which incorporates an anti-reflective coating to enhance legibility under various lighting conditions. The watch is engineered for a water resistance of 5 bar, which is equivalent to a depth of 50 meters or a pressure of 73 psi. The dial is rendered in a Deep Blue color and features applied indices and hands treated with Super-LumiNova for visibility in low-light environments. A date aperture is positioned at the 6 o'clock mark for functional symmetry.

Powering the timepiece is the Caliber H-10, a self-winding automatic movement. This three-hand caliber is notable for its extended power reserve of 80 hours. For this American Classic model, the movement is finished with intricate contrasting snail and pearled patterns. The case accommodates a 20mm lug width for strap attachment. The supplied strap, reference H6003841121, is made from brown cow leather and secures to the wrist using a traditional pin buckle. The stainless steel buckle itself has a width of 18mm, providing a slight taper from the lugs for wearing comfort.
