With its distinctive square case and bold dial architecture, the Monaco remains one of the most recognisable expressions of avant-garde Swiss watch design.
For TAG Heuer, the chronograph is not merely a complication but rather a foundation of its identity. The Monaco Evergraph makes that position explicit through its most radical interpretation yet in the form of a timepiece that reconsiders how precision is mechanically constructed.
The TAG Heuer Monaco Evergraph stands as a pinnacle of achievement when it comes to chronographs.
At its core sits the Calibre TH80-00, a movement defined by a decisive departure from convention. Traditional levers and springs are replaced by compliant components, reshaping how motion is controlled within the chronograph architecture.
Operating at 5 Hz with a 70-hour power reserve and COSC certification, it is reinforced by the in-house TH-Carbonspring oscillator, engineered for heightened magnetic resistance and long-term stability. The result is not incremental refinement, but structural rethinking — a chronograph rebuilt from within.
A LEGACY BUILT ON PRECISION
The Centigraph Le Mans, capable of 1/1000th-second precision.
Visually, the Evergraph remains anchored in the Monaco language. Its open-worked construction exposes the mechanical logic beneath, while the reworked case sharpens proportion and presence without erasing its architectural identity. It is evolution rendered visible, rather than declared.
That level of reinvention is inseparable from a lineage that began in 1860, when Edouard Heuer established a workshop dedicated to precision timing. In 1887, the oscillating pinion patent transformed chronograph construction, simplifying mechanics while improving reliability — a principle that remains foundational to modern chronograph engineering.
From there, innovation became a sequence of measurable thresholds. The 1916 Mikrograph brought 1/100th-second accuracy to sports timing, redefining what mechanical measurement could achieve. In 1962, a Heuer stopwatch accompanied astronaut John Glenn into orbit, extending Swiss precision beyond Earth itself.
MOTORSPORT AND MODERNITY
Worn by Steve McQueen in Le Mans, the TAG Heuer Monaco became an enduring emblem of motor racing style and chronograph history.
By the 1960s, the chronograph had become cultural as much as technical. The Carrera, introduced by Jack Heuer, distilled motor racing into clarity of design — functional, restrained, uncompromising. Then, in 1969, the Monaco and the Calibre 11 introduced the world’s first commercialised automatic chronograph, redefining mechanical independence on the wrist.
Worn by Steve McQueen in Le Mans, it became inseparable from the visual language of speed and modern performance. Across decades of motorsport timing, endurance sport and technical innovation, TAG Heuer chronographs have consistently operated in the space where measurement becomes meaning — where fractions of time define outcomes.
TAG Heuer’s Evergraph proves the chronograph is not just timeless—it’s constantly evolving.
Today, the Monaco Chronograph continues that evolution with refined titanium construction and the in-house TH20-11 calibre, balancing heritage with contemporary execution. Yet it is the Evergraph that reframes the trajectory entirely — not as an update to an icon, but as a redefinition of what the chronograph can be.
More than 160 years after the first oscillating pinion, the promise remains unchanged. The chronograph is still not finished. It is still being rebuilt — one fraction of a second at a time.
