The screw-down case back features the Sherpa clamshell hallmark, 'ENICAR' and 'STAINLESS STEEL INCABLOC - ULTRASONIC - SHERPA' on the outside, along with its unique reference numbers. The case measures 40 mm in diameter and is sharp and thick, retaining its definition.
This Enicar Sherpa Graph 300, with serial number 314 XXX has a round, stainless steel ‘BREVET’ case with large chronograph pushers and an original, Saturn cross-patterned crown. These chronographs were intended to be tool watches and were used as such in a range of professional endeavors.
The “Sherpa” name is inspired by that of the resilient local carriers of the 1956 Swiss Himalayan expedition to Everest, which relied on Enicar timepieces. Enicar’s association with motorsport also extends to British Formula One Champion Stirling Moss, who chose Enicar’s Ultrasonic Sherpa Chronometer as his personal timekeeper during time trials. By the time of his passing, Jim Clark was motor-racing’s most successful winner, with 25 Grand Prix victories to his name.
Colloquially referred to as the 'Jim Clark”, the watch was made famous by renowned British Formula 1 driver Jim Clark OBE, who was often photographed wearing the reference.
