Scale: 31 mm case
Cartier
Tank Must extra large automatic
WSTA0141
$5,700
Office, formal, everyday
This is the classic rectangular dress watch with an in house automatic, blued sword hands and a flinque dial, at roughly half the price of other Cartier steel automatics. At 41 by 31 mm and 8.4 mm thick it slips under a cuff, and the quick release strap system makes swapping looks easy. Nothing else at this money carries the same design history or reads as clearly formal.
It is the most recognisable rectangular dress watch you can buy new under EUR 6,000.

What owners say
WatchUSeek owners say the XL wears smaller than its name thanks to rounded brancards, and many prefer it on leather because the steel bracelet feels heavy for so thin a case. The date window divides opinion, and one owner reported a reserve under 24 hours when off the wrist.

WSTA0141 is assumed to be the current strap reference replacing WSTA0040 (same specs listed). caseDiameterMm is the 31 mm width; lugToLugMm is the 41 mm case length.
