The Intra-Matic H38455781, seen from the bench

The Hamilton Intra-Matic H38455781 is a contemporary reinterpretation of an iconic American watchmaking model from the 1960s, featuring a 38mm stainless steel case with Pan-American design aesthetics. It houses an ETA caliber 2892-A2 Swiss movement providing hours, minutes, seconds, and date functions with reliable timekeeping. The 316L stainless steel case offers corrosion resistance and uniform patina development, with a 20mm lug width designed to maintain visual balance for medium-large format wristwatches.
