A new chapter begins for the TAG Heuer Carrera: Overwhelming originality proven in its 60th anniversary (Part 1)

Since its birth in 1963, the TAG Heuer Carrera has been a timeless icon of the chronograph for 60 years. While inheriting its great heritage, it has also paved its own path of evolution. Its innovative watchmaking reflects TAG (Technique Avant-Garde), or cutting-edge technology. Discover its new world through the collection celebrating its 60th anniversary.

The origins of the legend lie in a brutal car race

　The inspiration for adopting the name of this classic TAG Heuer chronograph and infusing it with motor racing DNA came from the legendary Carrera Panamericana Mexico, a road race held only five times in Mexico in the early 1950s.

　Jack Heuer, the great-grandson of company founder Edouard Heuer, who became president of Heuer in 1962 at the young age of 30, heard about this dangerous car race while watching the 12 Hours of Sebring in Florida in 1962. The Spanish word "carrera" has various meanings, including "race," "run," "journey," and "trajectory." As he was developing a new chronograph, he felt that "Carrera" would be the perfect name for a watch that would symbolize a new era: concise, easy to remember, yet meaningful.

　According to what I heard directly from Jack Heuer himself, he was involved in everything from product development to design at the time. "At that time, typical chronographs didn't pursue design at all and were lagging behind other fields. I was interested in modern design, especially contemporary architecture, and I wanted to use the ideas I got from that in the Carrera," he said.

　Jack Heuer's vision of modern design was embodied in a dial that prioritized functionality and legibility with an easy-to-read layout, as well as modern lugs that extended from the case. He also devised a structure that secured water resistance by fixing the plastic crystal of the time with a steel tension ring. Furthermore, he moved the scale (the 1/5 second scale on the original model) from the flat surface of the dial to the tension ring, streamlining the dial. Both were groundbreaking at the time.

　Among the earliest Carreras, released in 1963, the Ref. 2447 is considered the origin of the lineage that continues to this day. Its movement is the renowned Valjoux 72. It has a three-dial configuration with 30-minute and 12-hour counters and a small second hand, and does not display a date. 1963 was also the year that the Rolex Cosmograph Daytona chronograph, which also has a deep connection to motorsports, was born. The movement installed in this model is also based on the Valjoux 72. These commonalities make the Carrera theory intriguing.

　The Carrera, with its mechanical movement based on the 60s design, returned to the scene in 1996, and this year marks its 60th anniversary. The latest Carrera embodies cutting-edge technology, symbolized by the word "TAG," as well as a free spirit and enterprising spirit.

Emphasis on traditional and innovative design

To celebrate the 60th anniversary of the TAG Heuer Carrera, TAG Heuer has reworked and improved the iconic design that has been loved for many years. Unveiled in 2023, the refresh extends to the case, dial, sapphire crystal, chronograph pushers, and movement. The result is an innovative design that exquisitely blends traditional design elements dating back to 1963 with modern updates.

　The Carrera has seen many variations over the years, but this latest renewal and update has a distinctive feature: a return to its roots and a forward-thinking approach to the design. In other words, the classic design has been reinterpreted and reborn with contemporary styling.

　First, there's the small case. The latest model features a 39mm diameter. This is the same as the "Tag Heuer Carrera 160th Anniversary Silver Dial Limited Edition," released in 2020, which faithfully reproduces the 1964 design. That same year, the "Tag Heuer Carrera Calibre Heuer 02 Chronograph," a new-generation model inspired by 1960s design, was launched, featuring a 42mm case and the Heuer 02 movement. However, the case of this model is subtly different from both the 39mm diameter of the reproduction model and the 42mm diameter of the new-generation model. The overall proportions of the case, including the distinctive lugs, have been ergonomically redesigned for a comfortable fit. The chronograph pushers have also been repositioned and reshaped for easier use.

　Another distinctive feature is the sapphire crystal, which replicates the "glass box" design popular among collectors, recreating the domed crystals of the past. The crystal, measuring 1.5 mm thick and 37.9 mm in diameter (actual size), is molded to seamlessly continue along the curved tachymeter scale, covering the entire dial.

　This unique shape was developed to coincide with the 60th anniversary of the Carrera, and the way it creates a bezel-less appearance is truly impressive. Another noteworthy feature is the concave curve of the seconds track flange and hour markers on the outer edge of the dial, which can be seen through the convex sapphire crystal. In fact, this concave shape makes the seconds track and indexes easy to read when viewing the dial not only from above but also from an angle. It goes without saying that this innovative design is in line with the functional beauty of the modern chronograph design that Jack Heuer aimed for with the original Carrera. Despite differences in era and styling, the avant-garde spirit remains consistent.

　One of the new TAG Heuer Carrera Chronographs released this year features a striking black dial with silver subdials, commonly known as the "reverse panda" design. This is a particularly popular pattern among the various models from the 60s. There's another detail that enthusiasts won't want to miss: the discreetly placed date display at 12 o'clock. This is a reference to the extremely rare model 2447SN, produced in very limited quantities in the late 60s. Another highlight is the perforated calfskin strap, which evokes the atmosphere of the heyday of car racing.　

　The new regular model, the TAG Heuer Carrera Chronograph, features an exquisite 39mm case that is reminiscent of the 36mm diameter used in the original Carrera, while also exuding the presence of a modern chronograph.The latest modern design also highlights the essence of vintage elements, allowing you to rediscover the charm of this classic more than ever before.

Technology implementation to refine practicality

The new TAG Heuer Carrera Chronograph, commemorating the 60th anniversary, comes in two colors: black and blue. The black model incorporates a reinterpretation of classic elements from the manual-winding era, while the blue model, also a chronograph but with a date display at 6 o'clock, has a modern feel reminiscent of the automatic-winding Carrera, and its styling makes the most of the colors to create an impression of a new generation Carrera.

　The black and blue TAG Heuer Carrera Chronographs differ in terms of dial color and style, but share common elements, such as a new 39mm case, a glass-box sapphire crystal crystal, a bezel placed inside the crystal, and highly visible flanges and indexes.

　Another thing the two models have in common is the automatic chronograph movement. It replaces the Caliber Heuer 02 used in the current Carrera Chronograph, and is considered an evolution of the TH20-00. The inclusion of a next-generation chronograph movement and simultaneously updating both the exterior and internal mechanisms is significant. These are not simply design variations, but rather innovations that will ensure the perpetuation of this classic.

　Developed under the supervision of TAG Heuer's movement director, Carol Cazapi, this movement, named "TH20-00," features an improved automatic winding mechanism. While the Heuer 02 had a unidirectional winding system that wound the mainspring only when the rotor rotated counterclockwise, the TH20-00 has been changed to a bidirectional winding system that can wind the mainspring regardless of the rotor's rotation. While the bidirectional winding system has a larger dead angle, it improves the efficiency of winding the mainspring when the arm is moving more actively.

　A key role in this bidirectional winding mechanism is played by the reverser, which converts the bidirectional rotor into unidirectional winding. This reverser utilizes ceramic bearings for high winding efficiency and durability. Highly efficient winding ensures the mainspring is always nearly fully wound, which of course helps stabilize power and torque and maintain high precision. Furthermore, according to TAG Heuer, the new mechanism minimizes the rotational noise and vibration inherent in unidirectional winding rotors by switching to a bidirectional winding system. Additionally, the power reserve is approximately 80 hours, the same as the Heuer 02. As a modern automatic chronograph movement, the Caliber TH20-00 offers ample practicality.

　Not only the new movement, but also the details that make up the functional design have all been calculated to improve practicality. The domed sapphire crystal, which sits on the case with the sharp, architectural design unique to the Carrera, is anti-reflective on both sides, allowing a clear view of each element of the dial: the totalizers and small seconds with concentric azure-finish patterns, the faceted hands and applied indexes, the domed tachymeter scale, and the sloping flange. As with the black model, all of these clever, three-dimensional details that make use of curves have been calculated to provide excellent visibility.

　Another feature not to be missed is the date display at 6 o'clock. This position allows the date display to be read without being obstructed by the chronograph second hand, even when it is stopped at 12 o'clock. The black model follows historical design principles and places the date display at 12 o'clock, but the blue model's focus is on practicality.
