Watches

Chronosport Sea Quartz 30

Worn by Tom Selleck as Thomas Magnum. Before the Pepsi GMT-Master, Magnum wore a Chronosport Sea Quartz 30 through the first three seasons, a 300 m quartz diver that fits his ex-Navy SEAL and UDT frogman background. It was retired when the Rolex arrived in the fourth-season episode "Home from the Sea." (Watchonista) Montres de Luxe independently identifies the same steel Chronosport Sea Quartz, noting that the Pepsi-bezel GMT-Master most enthusiasts remember was not Selleck's only watch on the 1980s series. (Montres de Luxe) Watches of Espionage's 2026 profile of the show's watches dates the Sea Quartz 30 to 1977, describes a Tropic-style rubber strap, 300 metres of water resistance, an acrylic bezel insert and the MRP-made "Monnin case", credits the choice to "the show's prop masters" rather than paid placement, and records Momentum's 2023 revival of the model.

Rolex GMT-Master 1675

Worn by Tom Selleck as Thomas Magnum. Magnum's Pepsi-bezel GMT-Master, which arrived in the fourth season to replace the Chronosport, became as much a part of the character as the Ferrari and the mustache. Montres de Luxe independently identifies the same steel Rolex GMT-Master I "Pepsi." (Montres de Luxe) Watches of Espionage reads the Rolex as "likely reference 16750 but potentially also a 1675", leaving the reference this row asserts open; it traces the watch's backstory to the fourth-season opener "Home from the Sea", in which a flashback shows Magnum's naval-aviator father promising a GMT like his own and a young Thomas wearing an oversized GMT at the funeral, and notes that a 1675, or the 1955 6542 before it, would postdate a father killed in Korea. It reports that Selleck kept the screen-worn watch after the 1988 wrap. (Watches of Espionage) Revolution's Ebel piece likewise names the watch, without argument, as the Pepsi "Rolex GMT-Master reference 16750", a second source for the 16750 reading against the 1675 this row asserts.
