Hamilton American Classic intra-matic

Hamilton Intra-Matic: the elegance of the past with today’s technology 

At Maison Roca, we are passionate about pieces that tell a story, and Hamilton Intra-Matic watches are a perfect example. With over 130 years of history, Hamilton is a brand that has managed to keep its innovative spirit alive without giving up its classic charm. Today, we present two of its most beloved icons: the Hamilton American Classic Intra-Matic Auto-Chrono and the Chronograph H — two watches inspired by the 1960s but made for lovers of contemporary luxury. 

American Classic Intra-Matic Auto-Chrono 

A modern tribute to vintage chronographs 

This model is a reinterpretation of Hamilton’s first automatic chronograph, launched in 1969. The American Classic Intra-Matic Auto-Chrono stands out for its timeless elegance and retro aesthetic, featuring a 40 mm stainless steel case and a dial available in two iconic combinations: 

  • White with black subdials (known as “panda”) 
  • Matte blue with white subdials (the “reverse panda”) 

Powered by the automatic H-31 movement and offering a power reserve of up to 60 hours, this watch is not only beautiful but also reliable and water-resistant (up to 100 m).

Hamilton Intra-Matic Chronograph H 

The art of mechanical simplicity 

For enthusiasts of manual movements and pure design, the Chronograph H is a gem with a soul of its own. Inspired by models from 1968, this watch preserves a classic essence with a contemporary touch. 

It is powered by the H-51 caliber, a hand-wound mechanical movement offering a 60-hour power reserve. Visually, its bi-compax layout (just two subdials) and box-style sapphire crystal give it a clean, refined air.

  • Black background with white subdials

To complete the look, choose between a calfskin leather strap or a stainless steel Milanese bracelet.
