Cartier Must 21

Jewellery, watches and silver

The Cartier Must 21 is a steel wristwatch line from Cartier's accessible Must de Cartier collection, featuring the Roman numeral dial design derived from the Tank Must line. It includes variants such as the quartz Must 21, the Autoscaph with automatic movement, and the sporty Chronoscaph chronograph with a stainless steel case and rubber or steel bracelet. The line sits at the entry level of Cartier's range, offering recognisable Cartier styling at a more accessible point than the gold Tank models.

We recognise this model across the auction sites and keep every one we see together.

On a used one

Check the battery compartment and crown seals for water damage on quartz versions, and have the movement serviced if unknown history exists. On Chronoscaph models inspect the rubber strap and pushers for wear, and verify the dial and hands are original as reprinted or replaced dials are common.

Not at the moment. The lots of this model that come to auction appear on this page while they are open, and every sale that closes with a price is added to the table.

Are the Cartier Must 21 hammer prices free to read?

The oldest sale of every model is free to read, and so is every hammer price under the site's floor. The other 20 hammer prices of the Cartier Must 21 open with an account: every sale of the model for a year, or one sale on its own.

Hammer prices are what the auction house recorded when the lot closed, before the buyer's premium, in the currency of the sale. A sale listed on a house's own site and on its platform counts once. Doubt a figure? Open the sale and its listing is linked there. How prices are recorded.
