Overview
The Cartier Tank Must Large in reference WSTA0055 presents the iconic Tank silhouette in stainless steel with a vivid blue lacquered dial, free of numerals and anchored only by the classic Cartier sword hands and Roman chapter ring. Introduced as part of the revived Tank Must line in 2021, it pairs a high-autonomy quartz movement with the refined proportions of the Large case — 33.7 mm × 25.5 mm — making it equally suited to formal and everyday wear. The blue dial gives the historically conservative Tank vocabulary a contemporary inflection without departing from the line's century-old design language.
History
The Tank Must name was originally associated with Cartier's accessible, vermeil-cased quartz models of the 1970s and 1980s, which introduced a generation of collectors to the Tank form. Cartier revived the Must designation in 2021 with a thoroughly modernised collection, now rendered in stainless steel and offered in a range of lacquered dial colours, of which the blue variant quickly became one of the most discussed. The WSTA0055 sits within the Large size tier, occupying the middle ground of the relaunched Must family and appealing to collectors who favour the Tank's architectural geometry in a wearable, low-maintenance format.
Notable points
- Stainless steel case measuring 33.7 mm × 25.5 mm — a size that reads as substantial on the wrist while remaining true to the Tank's rectangular heritage.
- Blue lacquered dial carries no applied numerals, relying entirely on the Roman chapter ring and blued sword hands for legibility.
- High-autonomy quartz movement prioritises reliability and extended battery life over mechanical complexity, consistent with the Must line's practical ethos.
- Part of the 2021 Tank Must relaunch, one of Cartier's most closely watched collection revivals of the decade.
- The absence of a date complication preserves the dial's clean, uninterrupted geometry — a deliberate design choice in keeping with Tank tradition.
