TAG Heuer is set to revolutionize the world of chronographs with its latest creation, the Monaco Evergraph. This innovative timepiece, introduced in 2026, transcends mere aesthetic updates, focusing instead on a profound mechanical re-engineering. At its heart lies the groundbreaking calibre TH80-00, which fundamentally rethinks the chronograph's start, stop, and reset functions. Moving away from the conventional array of levers, springs, and column wheels, the Evergraph employs compliant, flexible mechanisms developed by the TAG Heuer Lab. These microscopic bending structures enable precise triggering of functions, offering a future vision for chronograph construction that prioritizes durability and consistent performance. This watch is not just a new model; it's a testament to avant-garde watchmaking, promising an unparalleled tactile experience and setting a new standard for horological innovation.
Detailed Report on the Monaco Evergraph: Design and Engineering Marvels
The Monaco Evergraph watch, released in April 2026, emerges with a distinctive 40mm square case, meticulously crafted from either natural grade 5 titanium or black DLC-coated titanium. Both versions showcase a blend of brushed and polished finishes, characteristic of the iconic Monaco line. A nod to its heritage, the traditional left-hand crown is maintained, reminiscent of the original 1969 Monaco reference 1133, complemented by elongated chronograph pushers on the right side. Ergonomic enhancements include subtly reshaped profiles and sharper facets, ensuring a comfortable wear. The watch boasts a square sapphire caseback that perfectly mirrors the movement's geometry, providing a rare and cohesive design. With a water resistance of 100 meters, it offers both elegance and practicality.
The dial-side presents a transparent plate, revealing the intricate inverted construction of the movement. Key components like the barrel, gear train, and balance are visibly positioned, creating a captivating display. The layout features running seconds at 9 o'clock and chronograph minutes at 3 o'clock, framed by two gracefully arched bridges for the barrel and escapement. These curved elements echo the design language seen in TAG Heuer's recent Monaco split-seconds chronographs, reinforcing the watch's identity.
The natural titanium model features striking blue opaline chronograph counters, harmonizing with the technical architecture of the movement. In contrast, the black DLC-coated variant opts for a more subdued, instrument-like aesthetic with black counters and matching coated bridges. Applied markers float above the mechanism, while the openworked hands, adorned with red lacquered tips and Super-LumiNova treatment, ensure readability. A vibrant red-lacquered central chronograph hand sweeps across the dial, maintaining legibility amidst the complex technical presentation.
The core innovation lies within the calibre TH80-00, an automatic chronograph developed in collaboration with Vaucher Manufacture Fleurier over five years of dedicated research. Operating at a high frequency of 5Hz (36,000 vibrations/hour) and offering a 70-hour power reserve, this movement is chronometer-certified by COSC. It integrates TAG Heuer's TH-Carbonspring Oscillator, enhancing magnetic resistance and long-term stability. The most significant advancement is the replacement of traditional levers, springs, and cams with two bistable precision-engineered compliant mechanisms, manufactured using LIGA technology. One mechanism manages the start/stop function, while the other handles the reset. These monolithic components achieve motion through controlled elastic deformation, eliminating friction, mechanical play, and wear points associated with conventional designs. The start-and-stop mechanism utilizes a buckled blade that snaps between two stable positions, ensuring precise transitions. The reset hammer, with its complex geometry, simultaneously returns both chronograph hands to zero. This design guarantees a crisp and consistent tactile feel for the pushers, maintaining performance even after extensive use, thanks to ceramic components in high-stress areas that reduce wear and lubrication needs. The movement's technical finishing, featuring sandblasted and brushed surfaces, is complemented by a chequered-flag motif on the caseback and the signature shield-shaped rotor.
The Monaco Evergraph is presented on a rubber strap with textile embossing, paired with a new folding clasp equipped with double safety push-buttons, a welcome improvement for comfort, ease of use, and security. Available immediately and not limited in production, each version is priced at EUR 25,000, USD 25,000, or CHF 23,000.
The launch of the TAG Heuer Monaco Evergraph marks a pivotal moment in watchmaking, showcasing how persistent innovation can redefine established mechanisms. By embracing compliant mechanisms, TAG Heuer has not only enhanced the chronograph's precision and durability but also delivered a consistently refined user experience. This timepiece serves as a powerful reminder that true progress in luxury watchmaking extends beyond mere aesthetics, venturing into the core engineering that drives these intricate devices. It challenges watch enthusiasts and manufacturers alike to reconsider the possibilities of mechanical design, proving that the future of horology is not just about what a watch looks like, but how ingeniously it works.
