Founded in 1913 by the Racine family, Enicar ('Racine' backwards) grew in popularity thanks to their marketing tactic of supplying mountaineers and other adventurers with their watches in the 1950s. One particularly iconic event in Enicar's growth was when a team of Swiss climbers wore Enicar watches to the top of Lhoste and Mount Everest in 1956. As a result, Enicar registered the sub-brand "Sherpa" and began releasing its first Sherpa watches later in the same year to capitalise on this success. The Sherpa collection then grew and became a keystone of Enicar's brand, thanks to spin-off collections like the Sherpa Guide 600 GMT that we have here. Launched in the 1960s, the Sherpa Guide 600 GMT debuted as international travel became increasingly popular, and so those willing to embark on transcontinental journeys needed a watch to track more than one timezone, and so Enicar created the Sherpa Guide 600 GMT with its GMT hand. Operable through a second winding crown, this design mirrored other explorers watches like diver watches with a second winding crown to operate internal bezels. Boasting a black bezel with a litany of differen time zones depicted as cities, the Sherpa Guide 600 GMT is one of the earliest globe-trotting tool watches that hit the market.

Watch is in good overall condition. The case shows signs of extensive wear, with soft edges. The caseback is well worn, and while the serial number is visible upon close examination, other engravings along the caseback are very difficult to read. The bezel insert is faded and worn along the edge, and the red triangle pointer on the bezel is damaged. The original dial is in very good condition, with some wear visible on the surface, darkened luminous plots and various signs of aging. Hands have some marks and damage, with the pattern on the 24 hour hand missing in some places.

A tool watch in its purest form the Sherpa Guide 600 GMT was a watch designed to be useful above all else, and so today it remains as a beacon of unadulterated vintage tool watch design.
