MTO Crocodile Leather Strap in Brown (Semi-Glossy) for Cartier Tank

There are 2 ways to find out if your Cartier Tank is a Must or a Solo model:

1. Check the case design and dial details
Tank Must: Usually features minimalist dials without a date window, a Cartier logo, and classic Roman numerals. Most Tank Must watches have a solid caseback and no visible screws on the bezel.
Tank Solo: Often has a date window (in Large and Extra-Large sizes), blued-steel hands, and a slightly thicker case profile. The Tank Solo frequently includes a brushed case side and polished bezel contrast.

2. Check the model number
The model reference number is engraved on the case back.
Your warranty card, certificate, or purchase receipt will also list the model reference, which you can look up to confirm whether it is a Must or a Solo.

Examples of model references:
Tank Must:
WSTA0041
WSTA0042
WSTA0043
WSTA0052

Tank Solo:
W5200003
W5200013

16 mm lug width – Small model
19 mm lug width – Large model
23 mm lug width – Extra-Large model

Cartier Tank Solo:
17 mm lug width – Small model (some references may measure very slightly larger, e.g., 17.5 mm)
20 mm lug width – Large model
22.5 mm lug width – Extra-Large model

2. Check the model number:
The model reference number is engraved on the case back. Your warranty card, certificate, or purchase receipt will also list the model reference, which indicates whether your watch is a Tank Must or a Tank Solo, and the size.

Large: WSTA0042, WSTA0052
