Quick TakeThere’s an undeniable cool factor baked into the DNA of the Intra-Matic Auto. It’s a throwback that doesn’t feel like a costume. The sunburst blue dial shifts with the light, moving from a deep navy to a vibrant cobalt, making it a dynamic centerpiece that’s never boring. Paired with that slick Milanese mesh bracelet, it channels a pure mid-century aesthetic that's both sophisticated and effortlessly wearable. But this isn't some fragile vintage piece; it's a modern machine through and through. The H-10 automatic movement hums inside, packing a weekend-proof 80-hour power reserve. You can set it down Friday evening and pick it up Monday morning without missing a beat. The 40mm case hits the sweet spot for presence and comfort, while the sapphire crystal and practical 50-meter water resistance mean you don’t have to baby it. It’s the perfect blend of vintage soul and contemporary engineering—a watch for someone who appreciates the past but lives firmly in the present.

DescriptionThe Hamilton Intra-Matic Auto, reference H38425140, is engineered with a case constructed from stainless steel, measuring 40mm in diameter and 10.95mm in thickness. Its architecture provides a water resistance rating of 5 bar, equivalent to 50 meters or 73 psi, ensuring durability for daily wear. Protecting the dial is a sapphire crystal treated with an anti-reflective coating to maximize legibility under various lighting conditions. The case design incorporates a lug width of 20mm, accommodating the specified strap system. The dial itself is rendered in a Deep Blue hue and features applied indices and hands treated with Super-LumiNova for visibility in low-light environments. A date complication is positioned at the 6 o'clock mark for functional symmetry.

Internally, the timepiece is powered by the Hamilton Caliber H-10, an automatic self-winding movement. This three-hand mechanism is notable for its extended power reserve of 80 hours, a significant increase over standard automatic movements. The H-10's design for the American Classic collection includes intricate contrasting snail and pearled patterns, visible details that underscore its mechanical complexity. The watch is secured to the wrist by a stainless steel mesh bracelet, strap reference H6053841041, which terminates in a folding clasp. The buckle width measures 20mm, matching the lug width to create a seamless and integrated look from case to closure.
