Why people buy it
The Tank is Cartier's rectangular classic, and one of the best-known dress watches ever made. The steel Tank Must is the easier way in; the gold Tank Louis Cartier is the more traditional, dressier one.
What to check on a pre-owned Tank
- Tank Must or Tank Louis Cartier: the Must is steel; the Louis Cartier is gold with a slimmer case. They are priced very differently, so check which you're buying.
- Movement: many Tanks are quartz; some are hand-wound or automatic. Check what the listing says against the reference.
- Crown: the blue cabochon (spinel or sapphire) should be intact.
- Dial: Roman numerals should be crisp; Cartier hides a small signature in one of the numerals on many models.
- Strap: leather straps wear quickly; a genuine Cartier strap and deployant buckle are worth asking about.
- Gold models: check hallmarks.
- Papers: Cartier warranty, box and service history.
