The 6542 established the GMT-Master's rotating 24-hour bezel and additional hand. Rolex dates the GMT-Master to 1955 and says several airlines, including Pan Am, used it. Rolex's 2024 GMT-Master II brochure dates the Pan Am partnership to 1959. Sotheby's repeats an earlier request story in some catalogues. Its 2023 lot for Pan Am captain Clarence Warren documents one 6542 from his family and a 1959 Pan Am advertisement showing the watch. ~~The published~~ Pan Am provenance ~~attaches~~ to Warren's example.

The next reference, 1675, added crown guards and used an anodized-aluminum bezel insert. Rolex dates both changes to 1959. Steel and gold 6542s belong to the same reference, but their bezel and dial details differ.

Sotheby's records a circa-1958 steel 6542 from the family of Pan Am captain Clarence Warren. Its catalogue says the watch appears in a 1959 Pan Am advertisement and reports that the family believes Rolex gave it to Warren before a flight. This lot documents one captain's watch and its family history. The published Pan Am provenance applies to the Warren example.

Rolex's 2024 brochure says the GMT-Master's Plexiglas 24-hour insert was replaced by anodized aluminum in 1959, when the case also gained crown guards. Auction catalogues commonly call the early insert Bakelite. Rolex uses Plexiglas in its collection history; auction catalogues often use Bakelite for individual early examples. The ~~article follows~~ each source's ~~wording~~.

Each estimate and measurement above belongs to its individual sale entry. Sotheby's' 2023 gold-lot catalogue also gives a 1958 clasp stamp; that dates the bracelet; the watch head's date is separate. Christie's separately catalogues a circa-1959 yellow-gold 6542 with calibre 1065 and a 38 mm case.
