Quick TakeThis isn't just a watch; it's a statement pulled right from the golden era of motorsport and given a modern, aggressive edge. The Intra-Matic Auto Chrono in its black PVD guise is pure mechanical cool. It has this incredible presence on the wrist, where the deep, matte black case and dial make the vibrant orange accents absolutely ignite. That flash of color on the chronograph hand and peeking through the perforated rally strap is a direct nod to vintage racing gauges and leather driving gloves. You can almost hear the roar of a V8 when you activate the chronograph pushers. It’s a conversation starter that doesn’t shout, but confidently communicates a love for design, history, and performance. The watch perfectly balances its 1960s heritage with the robust, modern specs of the H-31 movement inside. It’s for the person who appreciates that true style is found where classic aesthetics and contemporary engineering collide.

DescriptionThe Hamilton American Classic Intra-Matic Auto Chrono, reference H38446732, is constructed with a 40mm stainless steel case that has a total thickness of 14.45mm. Its exterior surfaces are finished with a durable black PVD coating, resulting in a non-reflective, matte appearance. For strap attachment, the case is designed with a 20mm lug width. Protecting the black dial is a sapphire crystal, which has been treated with an anti-reflection coating to improve legibility across diverse lighting scenarios. The timepiece is engineered for a water resistance of 10 bar, corresponding to 100 meters or 145 psi. This level of integrity is reinforced by the implementation of a screw-down crown, which provides a secure seal against elemental intrusion. For functionality in low-light conditions, elements on the dial are coated with Super-LumiNova, and a tachymeter scale is printed on the dial's outer ring.

At the core of this watch is the Caliber H-31, a self-winding automatic chronograph movement. It is engineered with a Nivachron balance spring, which provides significant resistance to magnetic fields, shocks, and temperature fluctuations, thereby improving overall chronometric precision and reliability. The movement delivers an extended power reserve of approximately 60 hours. Its integrated functions include a chronograph with a 30-minute counter, a date complication, and a small seconds display, in addition to standard timekeeping. The caliber is distinguished by an H-pattern embellishment on the oscillating bridge. The watch is secured by a calf leather strap, reference H6000002131, which tapers to an 18mm pin buckle and features the Easy Click system for tool-free strap replacement.
