The Chronosport Sea Quartz 30 is a 300-metre quartz dive watch introduced in 1977 by Chronosport, a brand of the St. Moritz Watch Corporation, built on the tonneau Monnin case it shared with the military-issue UDT. The 42 mm steel case carries a screw-down crown behind a heavy guard and an ESA 536.121 quartz day-date movement, under a legible black dive dial and a 60-minute bezel. (A Guide to the Chronosport Sea Quartz 30) Its fame is borrowed from television: Tom Selleck wore one as Thomas Magnum for the first three seasons of Magnum, P.I. before the Rolex GMT-Master replaced it in the fourth.
