Cartier Must Tank LM, Ref. 6 81006, Cal. 81, 1986

Visible spider-net aging gives the cream dial of this Cartier Must Tank LM, reference 6 81006, its individual character. A vintage watch from 1986, it pairs Roman numerals and blued hands with a gold-plated silver case. The unisex quartz model uses caliber 81 and is fitted with a new high-quality handmade brown leather strap.

Spider-net dial and Roman numerals

The warm cream dial retains its visible network of age lines. Large black Roman numerals frame the display, while the inner chemin-de-fer minute track gives it a defined rectangular structure. The Cartier signature sits beneath 12.

Blued hands provide contrast against the cream background and black numerals. The spider-net surface is a condition feature of this particular example, adding a finer pattern beneath the more prominent printed dial elements.

Gold-plated silver case with visible wear

The rectangular case measures 23 mm wide and 30 mm from lug to lug, with a 17 mm strap opening. Elongated side brancards establish the Tank outline, and the low profile keeps the case close to the wrist. The width and full lug span are separate measurements of this compact format.

The case of this vintage dress watch is silver with gold plating, with back engravings supporting that construction. Wear to the plating remains visible around the edges and corners. The warm finish is retained alongside these signs of use.

A blue cabochon crown is another distinctive exterior detail. Its color connects visually with the blued hands, while the gold-tone case frames the cream and black display.

Handmade leather and serviced quartz caliber 81

The new high-quality handmade brown leather strap has a rich tone and textured finish. It fits the 17 mm opening and complements the warm case color. It is a replacement accessory, separate from the original watch-head components.

Cartier caliber 81 is a quartz movement. This used example is fully serviced and fully operational. The original watch-head components are retained, and it comes with a 12-month warranty.
