Cartier Tank 590005

The 590005 sits inside a story that began with a pricing decision. Les Must de Cartier launched its silver-gilt watches in 1977 so that Cartier's classic shapes could be sold for far less than solid gold, and the first Must Tanks were hand-wound. The line then moved to quartz. No Cartier statement of the reason is cited; one specialist archive reads it as a practical choice that kept the watches thin and low-maintenance for buyers who were not collectors, which fits the watch but remains an interpretation. The 590005 is a product of that second phase, and none of its dated examples is mechanical. The same archive once described it as a hand-wound calibre 78-1 watch, then withdrew that in 2026 after finding every auction and dealer description listed quartz.

The dates are softer than they look. Archiva places dated 590005s between 1984 and about 1990; The Index gives a dating window of about 1990 to 1995, which it says is not a production span; an auction house catalogued one example circa 1995. Sellers add estimates from 1980 to 1998 that no archive supports. Read together, the documented evidence points to production through the late 1980s and early 1990s, but neither boundary is fixed, and the range 1984 to 1995 is a join of two windows, not a documented run. The calibre question is similar: Cal. 90 is cited by the databases, Cal. 690 by some dealers, and whether these are two calibres or one described two ways is not established.

Step back and the pattern says something about the line. Within about a decade the dials recorded in this one case run from the classical Roman face of the 1917 Tank to an Art Deco sector layout and a dial borrowed from a ring, which suggests that by then the Must Tank was being treated less as a watch design than as a shape Cartier could dress in whatever the moment wanted.

The 590005 is best framed by its own family: the other numbered quartz vermeil Must Tanks, one nearly the same size and one smaller. Neither is a documented predecessor or successor, but together they place the 590005 by size and calibre within the line.

A 590005 is bought on its dial and its plating. The movement is a quartz calibre and the case is described the same way across the records, so two watches under this number differ mainly in which dial they wear, whether that dial is original, and how much gold is left on the case. Plating worn through at the edges is normal and honest; Archiva notes that a case newly gold all over may have been replated, which collectors value less, and expects public results in the low thousands of dollars at most. The same archive calls this the Tank most often inherited, and that is usually how one arrives: a quartz Cartier from the line that first sold the Tank in silver-gilt, carrying its years in the silver now showing at its corners.
