Visual Description
The Ref. 2441 is the large Tank Louis with a date. Its 18k yellow gold case measures 25.5 × 33.7 mm by Sotheby's measure, and the crown is set with a sapphire cabochon. The dial is white or silvered, with black Roman numerals, a railroad minute track, the Cartier signature hidden in the VII and a date aperture at 3 o'clock. Blued steel sword hands sit under a sapphire crystal.
Catalogers describe the same pale dial in different words, from white, off-white and ivory to silvered, cream and frosted white. The watch photographed here shows hours and minutes only; Antiquorum and Bachmann & Scher each list a 2441 with a center seconds hand.
Reference Significance
The 2441 is the large quartz Tank Louis with a date. Its smaller companion is the Ref. 2442, a 22 × 29.5 mm time-only model. The 23 × 30 mm Ref. 8810 is the solid gold quartz Tank Louis of the 1980s and 1990s, and the hand-wound Tank Louis of the 1970s is the Ref. 78086.
Historical Context
Dated examples run from 1999 to about 2015. Bachmann & Scher dates its earliest to 1999, and Sotheby's catalogs one circa 2015, offered with its Cartier warranty.
In between, Antiquorum catalogs three as made circa 2000, and other examples carry papers dated 2005 and 2006.
What to Look For
Read the case back for the reference number, and check the dial for the Cartier signature hidden in the VII and the crown for its sapphire cabochon. The date window should sit squarely at 3 o'clock.
Catalogs disagree on the case back: Antiquorum counts eight screws on each of its examples and Bonhams eight on one dated circa 2010, while Sotheby's counts four. Check the brancards for polishing that has rounded their edges. The movement is quartz; ask for a photograph of it to read its caliber marking.
