Offered for sale is a remarkable TAG Heuer S/EL Digital Quartz Chronograph reference CG1123-0, one of the most iconic and sought-after TAG Heuer models among collectors and Formula 1 enthusiasts. Combining a highly unusual analog-digital display with strong motorsport heritage, this reference has become one of the most desirable watches from the legendary S/EL collection.
This particular example is in very good condition, with all functions operating flawlessly. The watch comes as a complete full set, including its original outer box, original presentation box, instruction booklet, and International Guarantee booklet dated 12.03.1995. The watch has been fully inspected and fitted with a new battery for reliable performance. It is fitted with an original TAG Heuer leather strap and original TAG Heuer buckle, both in new/unworn condition with no signs of wear, a rare feature for a watch of this age. The strap is suitable for wrists up to 19.5 cm.
Ayrton Senna, one of Formula 1's greatest legends and a long-time TAG Heuer ambassador, was frequently photographed wearing TAG Heuer S/EL models throughout his career. This strong association with Senna has made the S/EL collection particularly desirable among motorsport enthusiasts and collectors.
The watch features an innovative analog-digital display with two integrated digital windows at 4 and 8 o'clock, combined with a highly precise 1/100th-second chronograph. Its advanced functionality and distinctive design perfectly reflect the spirit of Formula 1 during the late 1980s and 1990s.
Adding further to its motorsport heritage, Michael Schumacher was also photographed wearing a TAG Heuer S/EL Digital Quartz Chronograph during the early years of his Formula 1 career. The connection to two of the sport's most celebrated drivers has helped establish this reference as one of the most iconic TAG Heuer watches of its era.
As one of the very few TAG Heuer S/EL Digital Quartz Chronographs available on the market today, and an increasingly difficult watch to find as a complete set, this example represents a rare opportunity to acquire a genuine piece of TAG Heuer and Formula 1 history.

Founded in 1860 by Edouard Heuer in Saint-Imier, Switzerland, TAG Heuer has always been driven by innovation, speed, and avant-garde design. From the racetrack to the wrist, TAG Heuer stands as a symbol of endurance, precision, and the spirit of competition. Today, headquartered in La Chaux-de-Fonds, the brand continues to push boundaries, blending Swiss craftsmanship with cutting-edge technology and a daring sense of style.
TAG Heuer’s revolutionary breakthroughs forever changed the world of watchmaking — beginning with the oscillating pinion, patented in 1887, a mechanism still used in chronographs today. In 1969, TAG Heuer introduced the Monaco, the world’s first automatic chronograph with a square waterproof case, immortalized on the wrist of Steve McQueen in the film Le Mans. The Carrera, launched in 1963, remains a legend among racing chronographs — a pure, functional design inspired by the dangerous Carrera Panamericana road race. The Autavia, originally created in 1933 for aviation and automobiles, evolved into a professional chronograph adored by adventurers and collectors alike.
Every TAG Heuer watch is built for those who live life in the fast lane — who value precision, innovation, and bold design. To own a TAG Heuer is to embrace a legacy of performance and passion; it’s a statement of confidence, energy, and timeless Swiss excellence that beats with the heart of motorsport.
