Originally produced in the early 1950s, the reference 6150 predates the official release of the Explorer, yet this example bears the iconic Explorer name on the dial, reflecting its place at the very beginning of Rolex’s legendary model lineage. This particular watch carries an extraordinary naval history. Sent to the Royal Navy around 1953, it is engraved with “H.S.10 CD” (Clearance Divers), a military serial number 931134, and the distinctive military crow’s foot marking. Only approximately 300 such watches were issued to the Navy, making surviving examples exceedingly rare. The watch remained with its original owner—a naval officer and ex-military serviceman—stored in a suitcase for nearly 40 years before being rediscovered by the current owner.
