The TAG Heuer Carrera Astronomer takes an innovative approach to moon phase display with a rotating disc that displays the seven stages of the lunar cycle. This 39mm stainless steel timepiece, unveiled at Geneva Watch Days 2025, combines 1960s inspiration with modern technology and is available in three versions, two of which are limited to 500 pieces.
Moon phases are often depicted in watchmaking as a romantic decoration, but TAG Heuer with the model Carrera Astronomer offers a more practical and accurate view of the lunar cycle. This watch, which draws inspiration from the space age of the 1960s, when the brand collaborated with NASA, combines simple elegance with a useful complication. If you're new to the world of watches, this model will help you understand how a watch can track natural cycles, like the moon's, without complicated calculations. Ironically, while Heuer watches once measured the speed of racers, they now track the rhythm of the moon - and with a style that would impress even astronaut John Glenn.
Innovative display of moon phases: From romantic to scientific
Most moon phase watches only show basic phases such as full and new moon, often hidden behind clouds or stars for aesthetic effect. The TAG Heuer Carrera Astronomer changes this with a rotating disc at 6 o’clock that displays seven illustrated phases of the moon throughout its 29.5-day cycle. Two slim hands track the daily progress, automatically advancing each day at 1 a.m., in line with the actual movement of the moon.
This approach is inspired by the space missions of the 1960s, when Heuer provided timepieces for astronauts like John Glenn. The watch is not only beautiful, but also useful – ideal for skywatchers or those who need precise information on the phases of the moon, for example to plan activities related to the lunar cycle. The stainless steel case measures 39 mm in diameter and 12.16 mm in thickness, ensuring comfort for everyday wear, with water resistance up to 100 meters, suitable for swimming or rain.
Three versions for different tastes: From classic to limited editions
The Carrera Astronomer collection includes three models that share the same base, but differ in color and material. The basic model has a silver dial with a black and white moon phase display, Arabic numerals and a distinctive “beads of rice” steel strap, reminiscent of a 1960s design. This version is part of the permanent collection and is ideal for those looking for a simple yet elegant watch that combines the brand’s history with modern functionality.
Two limited editions, each limited to 500 pieces, add more personality. The Turquoise model features a gray leather strap and a turquoise Super-LumiNova coating that glows even in the daytime, giving the watch a futuristic look that would make it fit for a space odyssey. The two-tone model features 18-karat rose gold accents on the dial, hands and middle links of the strap, adding warmth and luxury. The caseback of the limited editions features an engraving of the observatory, further enhancing the space-inspired theme.
Technical details: What powers this astronomical clock
At the heart of the watch is the Calibre 7 automatic movement, based on the Sellita SW385-1, with 28,800 vibrations per hour and a 50-hour power reserve. This means the watch can run without winding for more than two days, which is practically a worry-free weekend. The movement manages the hours, minutes, seconds and moon phase, with precision that matches the lunar cycle.
Straps are available in a steel “beads of rice” design or a grey leather variant with a folding clasp. All models have sapphire crystal with double anti-reflective coating for better readability. For those just entering the world of watchmaking: an automatic movement means that the watch winds itself through the movement of the wrist, without the need for batteries – simple but elegant.
Historical Context: How the 1960s Influenced Modern Design
The Carrera name comes from the Carrera Panamericana race of the 1950s, where Jack Heuer sought a watch with exceptional legibility for racers. In the 1960s, Heuer expanded its influence into space, with watches for NASA, including the timers worn by John Glenn during the first American orbital mission in 1962. The Carrera Astronomer continues this tradition, combining racing spirit with astronomical elements – instead of measuring speed on the track, it now tracks the rhythms of space.
This model retains the simple lines of the 1960s, such as contrasting colors and clear numerals, but adds a modern complication. The irony is that while watches once measured race time, they now measure space time – proof that history can inspire the future.
Price and Availability: When and How You Can Get It
The TAG Heuer Carrera Astronomer will be available from October 2025 through authorized retailers and the official TAG Heuer website. The basic steel model on a strap costs $4,800, while the leather version costs $4,600. The two-tone model with rose gold details is priced at $7,250.

Conclusion: The TAG Heuer Carrera Astronomer is a watch that combines affordability with innovation, suitable for enthusiasts and those just entering the world of watchmaking. With a precise display of the phases of the moon, it offers more than just time - a connection to the universe in everyday life. If you are looking for a watch that is at once practical, elegant and historically rich, the Astronomer is the right choice. With a little humor: while we all rush through the day, this watch reminds us to look up - towards the moon.
