On the wrist

How it wears, by wrist size

6.5-inch wrist

Ideal — the large Tank Must wears flat and elegant at this size.

7-inch wrist

Classic proportions; the rectangle reads refined rather than small.

7.5-inch wrist

Understated; consider the XL (WSTA0141/WSTA0053, 41 x 31mm, automatic) if you want more wrist presence.

8-inch wrist

Too discreet for most — the XL automatic is the better fit.

The Goat's verdict

Buy or skip?

Editorial take: 8.5/10 — the most honest entry into Cartier.

The Tank Must large gives you the real Tank — the 1917 design, the Roman dial, the spinel crown — for $3,500 instead of five figures. The quartz movement is a feature here: thin case, no winding, no fuss. What you give up is any pretense of horological prestige, and the pre-owned discount to retail says the market knows it.

Skip if…

  • You want a mechanical movement — step up to the Tank Must XL automatic or the Tank Louis Cartier
  • You want water resistance for daily sport — 30m is splash-only
  • You expect value retention like steel Rolex — entry Cartier depreciates like most watches; buy it to wear it

Quick answers

Frequently asked questions

Is the Cartier WSTA0041 discontinued?

No. As of our last check (2026-08-23) the Tank Must large is in current production and widely available.

Is the WSTA0041 the XL model?

No — WSTA0041 is the large model (33.7 x 25.5mm, quartz). The extra-large Tank Must (41 x 31mm, automatic Calibre 1847 with date) carries references like WSTA0141 or WSTA0053.

Is the Tank Must a good investment?

No — and that is liberating. It depreciates modestly like most quartz watches, so buy it because you will wear it for decades. Past performance is not a guarantee, and this is not financial advice.

Tank Must or Tank Louis Cartier?

The Must is steel and quartz at ~$3,500; the Louis Cartier is gold and mechanical at five figures. Same design DNA, very different propositions — the Must is the rational choice, the Louis is the romantic one.

What is the difference between the Tank Must and the old Tank Solo?

The Must replaced the Solo in 2021 with slightly refined case lines, a sapphire crystal on most models, and Cartier's quick-change strap system. Functionally they are near-twins.

Can I swim with the Tank Must WSTA0041?

No — 30m / 3 bar means splash resistance only. Keep it away from the pool.

Channels, ranked by risk

Where to buy safely

Authorized Dealer

The smart route — full warranty, Cartier Care extension to 8 years when registered, and zero authenticity risk.

Gray market / secondary dealers

Meaningful discounts pre-owned; check battery age and strap condition, and confirm box/papers.

Auction houses

Not worth it for a current-production Must — buy retail or pre-owned.

Private sales

Common and mostly safe at this price — still verify the serial and the secret dial signature before money moves.
