Hamilton has redefined its iconic Intra-Matic collection, building on a heritage that dates back to the ground-breaking Project 99. This collaboration between Hamilton, Büren, Heuer, Breitling, and movement expert Dubois-Depraz led to the development of one of the first automatic chronograph movements in 1969—the Chrono-Matic or Calibre 11, depending on branding. Over the years, Hamilton introduced the Chronograph A and B models, culminating in the 2017 Intra-Matic 68 Chronograph. Today, Hamilton reinvents the classic with a bold, modern twist—introducing a range of black-coated models accented with striking colours.

A Timeless Design with Modern Refinements

The latest Intra-Matic Auto Chronos pay homage to their predecessors with a familiar bicompax dial layout, a bottom-positioned date window, and pushers strategically placed on the right-hand side of the case. Unlike the original Chrono-Matic models, which featured a left-side crown, the new design integrates it seamlessly with the pushers for a cleaner, more balanced look.

Sleek, Stealthy, and Built to Last

Encased in a 40mm-wide, 14.45mm-thick stainless steel body with a black PVD coating, the new Intra-Matic models embody a sleek and understated aesthetic. The design stays true to its vintage roots with angular, faceted lugs, a sloping bezel, and vertical case sides. A curved sapphire crystal with an anti-reflective coating ensures clarity, while a solid, black-finished screw-down steel caseback enhances durability. Water-resistant up to 100 metres, this timepiece is engineered for both daily wear and adventure.

Precision and Performance at Its Core

At the heart of the watch is Hamilton’s Calibre H-31, concealed behind a caseback embossed with the brand’s H-logo. Though it does not share a direct lineage with the 1969 Chrono-Matic or Calibre 11, it is built upon the robust ETA Valjoux 7753. This movement features an upgraded gear train and a Nivachron balance spring, providing an impressive 60-hour power reserve. While an exhibition caseback might have added an extra touch of sophistication, the solid black caseback stays true to the watch’s stealthy persona.

Sporty Elegance with a Racing-Inspired Strap

To complement the watch’s bold character, Hamilton pairs these models with black perforated leather racing-style straps, secured with a blackened pin buckle. The orange and yellow versions include a coloured underlay beneath the perforations, adding a sporty touch. The Intra-Matic continues to be a standout chronograph in Hamilton’s lineup, merging vintage inspiration with contemporary craftsmanship. While it may not revolutionise the chronograph world, it remains a reliable, stylish, and highly wearable timepiece that balances heritage and modernity effortlessly.
