Notes

A highly important and exceedingly rare stainless steel automatic wristwatch, the present Rolex Explorer I reference 14270 “COMEX Everest” is one of the very few examples issued by Rolex in collaboration with COMEX (Compagnie Maritime d’Expertises) outside the field of professional diving. Produced in 1997, it stands as a unique testament to Rolex’s enduring connection with scientific exploration and human endurance.

That same year, COMEX conducted the groundbreaking Operation Everest III, a physiological experiment simulating a full ascent of Mount Everest within a hypobaric chamber in Marseille, France. Over the course of 31 days, eight male volunteers aged between 23 and 37 were exposed to progressively reduced atmospheric pressures replicating an altitude of 8,848 meters (approximately 253 mmHg). The study included a brief “descent” to 5,000 meters for recovery, while continuous cardio-respiratory and metabolic data were recorded to advance understanding of human adaptation to extreme hypoxia.

For this mission, Rolex supplied a very limited number of watches to COMEX personnel and participants, each specially engraved on the caseback “EVEREST 8848 m COMEX 1997.” Known examples include several professional models — the present Explorer I Ref. 14270, the GMT-Master Ref. 16700, the Submariner Ref. 16610, and the Oysterquartz Ref. 17000 — confirming that the issue was a small, multi-reference batch rather than a numbered series. Historical evidence suggests fewer than ten pieces in total, making this one of the rarest COMEX-linked Rolex productions ever recorded.

The present watch retains its 36 mm stainless steel Oyster case, smooth polished bezel, black lacquer dial with applied white-gold hour markers and tritium-filled Mercedes hands, powered by the automatic Calibre 3000. Offered with its original box, punched warranty, booklets, and COMEX documentation, this “COMEX Everest” Explorer is a remarkable and intellectually compelling timepiece — bridging Rolex’s historic ties from the deepest oceans to the highest peaks on Earth.
