Quick TakeThere is a certain effortless cool baked into the DNA of the Intra-Matic Auto Chrono. It's a throwback, a nod to the glory days of racing chronographs, but executed with a modern swagger. That deep blue dial with the contrasting cream-colored "panda" subdials isn't just trying to be vintage; it's redefining it. You feel the reliable heart of the machine, the H-31 automatic caliber, with its impressive 60-hour power reserve, ready for a long weekend adventure without needing a wind. This watch doesn't shout for attention, it earns it with its balanced 40mm case and the satisfying, tactile response of the chronograph pushers. The soft brown leather strap feels broken-in from the first wear, completing a package that is less a piece of jewelry and more a trusted co-pilot. It’s for the person who appreciates the mechanical soul of a watch and the stories it might tell, whether timing a lap or just the commute home.

DescriptionThe timepiece is constructed from a stainless steel case measuring 40mm in diameter with a thickness of 14.45mm and a lug width of 20mm. Its front is protected by a sapphire crystal treated with an anti-reflective coating to ensure optimal legibility. Water resistance is rated to 10 bar, equivalent to 100 meters or 328 feet, a capability supported by the inclusion of a screw-down crown for enhanced ingress protection. The primary dial is blue and features Super-LumiNova application for visibility in low-light conditions. Chronograph functions are managed via two pushers flanking the crown, and a tachymeter scale is printed along the dial's outer perimeter for calculating speed.

Powering the watch is the Caliber H-31, a self-winding automatic chronograph movement. This mechanism provides a substantial 60-hour power reserve. Its functions include central timekeeping, a date complication displayed in a window at the 6 o'clock position, and the chronograph. The movement's design is distinguished by an H-pattern motif on the oscillating bridge, a signature of its manufacturer. The watch is affixed to the wrist with a brown cow leather strap, which begins at a 20mm width and tapers to an 18mm stainless steel pin buckle for a secure fit. The specific strap reference for this configuration is H6003841121.
