Quick TakeThere is an undeniable charm to a panda dial, a certain ready-for-anything attitude that feels ripped straight from the golden age of motorsport. The Intra-Matic Auto Chrono channels that spirit perfectly. It’s not just a retro-inspired watch; it’s a modern mechanical powerhouse dressed in vintage clothes. The satisfying mechanical feedback from the chronograph pushers, the smooth sweep of the seconds hand powered by the robust H-31 automatic movement, and the impressive 60-hour power reserve mean it’s ready to go all weekend without a single wind. That off-white dial with its black sub-dials is pure class, equally at home under a shirt cuff as it is sticking out of a driving glove. The stainless steel mesh bracelet is the masterstroke, elevating the entire package from a simple sports watch to a piece of mid-century cool. It wears with a slinky comfort that leather or a traditional link bracelet just can’t replicate, making it an incredibly versatile daily companion with a story to tell.

DescriptionThis timepiece is constructed around a 40mm stainless steel case with a total thickness of 14.45mm. The design incorporates a 20mm lug width, ensuring compatibility with a range of straps. For maximum durability and legibility, the case is sealed with a sapphire crystal that features an anti-reflective coating. Engineered for resilience, the watch includes a screw-down crown, contributing to a substantial water resistance rating of 10 bar, equivalent to 100 meters or 145 psi, making it suitable for recreational water activities. The case houses a white dial configured with chronograph and date functions, surrounded by a fixed tachymeter scale on the outer chapter ring for calculating speed. For visibility in low-light conditions, Super-Luminova is applied to critical dial elements.

Powering the instrument is the Hamilton Caliber H-31, a self-winding automatic chronograph movement. This advanced caliber provides a significant 60-hour power reserve, a notable extension over standard chronograph movements. A distinguishing feature of the H-31 is the H-pattern design integrated onto the oscillating bridge, a signature of its manufacture. The watch is affixed to the wrist via a stainless steel mesh strap, identified by the reference number H6053841041. This strap terminates in a 20mm folding clasp, providing a secure and seamless closure that matches the lug width of the case for a cohesive aesthetic. The intricate construction of the mesh offers a unique combination of comfort and sophisticated style.
