SPECIAL Watches and Wonders -3

Episode 3: A closer look at the new TAG Heuer Monaco watches!

“Everything changes, but nothing changes!” That’s the motto doing the rounds in the corridors of the Watches and Wonders fair and at the TAG Heuer manufacture too. Frank Sans C was lucky enough to visit the manufacture during the fair, teleported there by none other than American actor Patrick Dempsey! We take an in-depth look at the Monaco from every angle and discover the two new models with our watch enthusiast: Julien Delcambre, Lead Designer, now nicknamed the “King of Design”; Nicholas Biebuyck, Director of Heritage; Laurent Kervyn, Head of the Haute Horlogerie Group; not to mention Carole Forestier-Kasapi, Strategic Director of Movements and Haute Horlogerie, otherwise known as the “Queen of Tourbillon”. The Monaco as we’ve never seen it before… with the added bonus of a tour of the carbon balance spring factory! A true exclusive.

TAG Heuer Monaco: an icon born of innovation

The history of the TAG Heuer Monaco is marked by pivotal encounters and major innovations. In 1969, Jack Heuer, then at the helm of the brand, crossed paths with Swiss racing driver Jo Siffert, fresh from his victory at the British Grand Prix. This encounter gave rise to the first partnership between a watch brand and a racing driver. The Heuer logo then appeared on a Lotus and on the driver’s racing suit, offering the brand unprecedented visibility. Behind this initiative lay a strategic objective: to support the launch of a revolutionary movement, the Chronomatic Calibre 11, the first automatic chronograph in history. This ambitious project began in 1967, when Jack Heuer conceived the idea of combining a Dubois-Depraz chronograph module with a Buren automatic calibre featuring a micro-rotor. Faced with the high cost of development, he joined forces with Willy Breitling. Together, they secretly led ‘Project 99’, which came to fruition two years later.

Après deux années de développement, le mystérieux « Projet 99 » aboutit en 1969 avec la naissance du premier prototype : le Chronomatic Calibre 11. Ce mouvement modulaire impose une configuration particulière, avec une couronne de remontoir placée à 9 heures, tandis que les deux poussoirs du chronographe restent placés à 2 et 4 heures. Une disposition peu conventionnelle dans un univers horloger encore très attaché aux traditions. Pourtant, le placement de la couronne à gauche est rapidement salué pour sa praticité. Confiant dans le potentiel de son calibre, le visionnaire Jack Heuer en fait même un argument marketing, affirmant que l’on reconnaît immédiatement « la première montre chronographe qui ne se remonte pas » grâce à ce détail unique. Et comme le calibre présente une configuration particulière, Jack Heuer décide d’aller encore plus loin dans l’originalité : il faut un boîtier hors du commun. Le choix s’oriente alors vers le tout premier boîtier carré « étanche breveté », développé par la société Piquerez. Jack Heuer en obtient l’exclusivité pour ses chronographes. Ainsi naît la « Monaco », baptisée en hommage au plus emblématique Grand Prix de Formule 1.

The Calibre 11 stands out for its original design, notably featuring a crown positioned on the left-hand side of the case, whilst the pushers remain on the right. This bold choice became a key selling point, symbolising a watch that no longer needed to be wound by hand. To complement this innovation, Heuer opted for an equally avant-garde design: a square, water-resistant case – a first at the time – developed by the Piquerez company. Thus was born the Monaco, named in homage to the legendary Formula 1 Grand Prix.

Despite its technical qualities and unique aesthetic, the Monaco initially struggled to win over the public. Its unconventional design and innovative positioning were somewhat bewildering. However, that same year, Steve McQueen discovered the watch whilst preparing for the film Le Mans. Keen to ensure realism, the actor chose to wear a Monaco, in keeping with the Heuer racing suit inspired by Jo Siffert.

This choice proved to be decisive: by appearing on the wrist of one of the greatest stars of her time, the Monaco gradually rose to iconic status. Initially misunderstood, it eventually became one of the most iconic models in contemporary watchmaking.

Everything changes, yet nothing changes!

From reissue to contemporary reinterpretation: the evolution of the TAG Heuer Monaco

Relaunched in 1997, the TAG Heuer Monaco marked the return of an icon, remaining true to the spirit of the original model. This revival was, above all, a reissue: bringing a legend back to life whilst preserving its historic hallmarks. Almost thirty years later, the current Monaco goes far beyond a simple evolution. It embodies a deeper reinterpretation, where respect for heritage and technical innovation go hand in hand. Whereas the 1997 Monaco revived a legend, today’s model propels it into the future.

A reimagined architecture: faithful yet transformed

Whilst the diameter remains unchanged at 39 mm, the case has been completely redesigned. Inspired by the original 1133 model, the new design retains the watch’s defining features — a square case, a left-hand crown and a distinctive construction — whilst subtly updating them.

Models from 1969, 2015 and 2026

The changes can be seen in the details:

  • a slimmer case with softened angles, giving it a more sculptural and streamlined appearance;
  • redesigned lugs and case ergonomics to significantly improve comfort;
  • thickness reduced from 14.3 mm to 13.8 mm,
  • a case middle now featuring a bevelled edge;
  • a redesigned bezel, more distinctly square and following the shape of the sapphire crystal;
  • revised push-buttons, typography and dial details, right down to the Super-LumiNova markers, which are now square rather than round
With improved ergonomics, enhanced comfort and guaranteed elegance, the new TAG Heuer is embarking on a new chapter in its history.

These changes may seem subtle, but they reflect a genuine commitment: to preserve all the signature features cherished by collectors whilst revitalising the design to appeal to a wider audience. The introduction of grade 5 titanium across all three models – combined with an 18-carat rose gold bezel on one of them – brings a new level of lightness and sophistication to the Monaco collection.

TAG Heuer Monaco Chronograph, a truly iconic trio.

A major technical glitch

It is particularly in terms of mechanics that the difference from the original model is most striking. The Monaco, relaunched in 1997, was built on a reliable but relatively conventional platform. The current generation takes a significant step forward with the in-house TH20-11 calibre, which radically transforms the watch’s offering.

The new Calibre TH20-11 now features a bi-compax layout, with sub-dials at three and nine o’clock and a date window at six o’clock – a layout that pays homage to the original Calibre 11.

This new movement features a bi-compax architecture inspired by the historic Calibre 11, a column wheel, an optimised winding mechanism and a power reserve of approximately 80 hours.
The display has also been updated, with the counters repositioned at 3 and 9 o’clock and a slanted date window at 6 o’clock, enhancing both legibility and visual identity. The Monaco thus evolves from a cult reissue to a true manufacture chronograph.

Modernisation right down to the way it’s worn

This transformation extends beyond the case and movement. Comfort and wearability have also been reimagined: an improved strap, a new pin buckle system, and a redesigned double folding clasp. These details contribute to a more contemporary take on the watch, designed with equal attention to both aesthetics and the wearing experience.

The new TAG Heuer Monaco Chronograph is fitted with a black perforated calfskin strap featuring a Grade 5 titanium folding clasp with a satin-finished and polished finish, complete with a double safety push-button.

TAG Heuer Monaco Evergraph: a flexible mechanical watch

With the Monaco Evergraph, TAG Heuer does more than simply revisit an icon; the manufacturer introduces a new take on the mechanical chronograph by combining visible architecture, high frequency and fundamental innovation. At the heart of this timepiece, the TH80-00 calibre marks a conceptual breakthrough, driven by a technology still rare in watchmaking: flexible bistable components.

TAG Heuer presents a groundbreaking mechanical design and a cutting-edge interpretation of its iconic square timepiece.

Traditional pivoting joints are being replaced by monobloc structures that deform with controlled precision. More than just a technical advancement, this flexible architecture redefines the very functioning of the chronograph. By drastically reducing friction points, mechanical play and inherent wear, the manufacture is paving the way for a more efficient, durable and stable complication.

Flexible bistable components replace traditional joints: they bend with extreme precision rather than pivoting and wearing out.

Furthermore, this mechanical revolution finds another spectacular expression in the TH-Carbonspring oscillator, the very heart of the movement, which was unveiled at the latest Geneva Watch Days. Developed and patented at the TAG Heuer Lab, this 5-hertz regulating organ — equivalent to 36,000 vibrations per hour — enables reading to the nearest tenth of a second, true to the brand’s chronograph DNA. But its uniqueness lies above all in its construction: ultra-light, non-magnetic and highly shock-resistant. In a nutshell: this oscillator combines the benefits of advanced materials with chronometric stability designed to last.

Rarely has such innovation been so directly integrated into a watch’s design. For the Monaco Evergraph lays its mechanics bare. Beneath an openworked dial, the barrel and the TH-Carbonspring are on full display, supported by two broad, architectural arches that lend depth and visual tension to the whole. Transparency here is not merely a stylistic choice, but a guiding principle: to make performance visible.
