Race-Ready since 1968 Inspired by its original racing roots in 1968, the Intra-Matic Auto Chrono welcomes a new interpretation of the iconic Intra-Matic design. A modern take on a vintage classic, the all-black 40mm PVD case, dial and perforated strap add a contemporary edge to a historical model that harks back to the late sixties. Inside this Intra-Matic beats the Hamilton H-31 — a powerful automatic chronograph movement featuring an extended 60-hour power reserve, making it perfect for the demands of the sportiest of timekeeping missions. With an H pattern design on the oscillating bridge, there’s no mistaking who made this movement.
