Quick TakeForget automatic convenience for a moment and embrace the connection. The Intra-Matic Chronograph H is a pure, tactile experience from a brand that knows its history. Winding the H-51 caliber each morning is a small ritual, a deliberate start to your day that connects you to the sixty hours of power you've just stored. On the wrist, the 40mm case just sings, a perfect modern size that nods to its vintage roots. That crisp, white panda dial is not just for looks; it is a high-contrast command center for timing life's important moments with a satisfying click of the pushers. The sapphire crystal with its anti-reflection keeps things brilliantly clear, and the whole package, secured by that slick stainless steel mesh bracelet, feels less like a simple time-teller and more like a co-pilot for your daily adventures. It is a watch with a soul, waiting for you to bring it to life.

DescriptionThe Hamilton Intra-Matic Chronograph H, designated by reference number H38429110, features a meticulously crafted case made from high-grade stainless steel. The circular case measures a nominal 40mm in diameter, with a vertical dimension, or thickness, of 14.35mm from the caseback to the apex of the crystal. The architecture provides a standard 20mm lug width, facilitating a secure connection for the bracelet and allowing for strap customization. A top-grade sapphire crystal serves as the protective interface for the dial; this material is selected for its superior hardness and is enhanced with an anti-reflection coating to mitigate glare and improve visual clarity. The dial is executed in white, configured with contrasting black subdials for the chronograph function. A tachymeter scale is precisely printed along the dial's periphery. For optimal legibility in ambient darkness, key dial elements are coated with Super-LumiNova.

Powering this timepiece is the Hamilton Caliber H-51, a specialized mechanical movement requiring manual winding. This design choice celebrates traditional horology and provides the user with direct tactile interaction with the watch's engine. The movement's mainspring, when fully wound, stores sufficient energy to deliver an extended 60-hour power reserve. Its functions include central hours and minutes, a small seconds subdial, and a central chronograph seconds hand complemented by a 30-minute counter. The robust case construction guarantees water resistance to a pressure of 10 bar, which corresponds to a static depth of 100 meters or 328 feet. The watch is paired with a stainless steel mesh bracelet, identified by strap reference H6053841041, which terminates in a matching stainless steel folding clasp. The clasp has a width of 20mm, maintaining the bracelet's proportions for a balanced aesthetic.
