This replica tank sta0040 41mm follows the elongated rectangular case design that has defined the Tank since 1917, updated in a contemporary format under the WSTA0040 reference. The visual identity comes from vertical brancards, the side rails that double as lugs and frame the dial in a continuous metal line from top to bottom. At 41mm in length the case provides more dial real estate than classic small Tank models while preserving the narrow proportions that distinguish the Tank from every round-cased competitor.

Technical Overview

• Case dimensions: 41mm length, rectangular
• Case material: stainless steel
• Dial: silver with painted Roman numerals
• Crystal: sapphire
• Crown: octagonal with blue synthetic spinel
• Strap: leather with deployment buckle
• Movement: automatic
• Functions: hours, minutes, seconds

The brancards extend seamlessly from the case body, creating an unbroken vertical line that gives the Tank its architectural character. Unlike round watches where lugs are separate elements, the Tank integrates everything into a single continuous form.

Inside the Movement

Cartier equips the WSTA0040 with an automatic caliber sized for the rectangular case. The movement delivers daily timekeeping with self-winding capability through a micro-rotor that keeps the profile thin. The sapphire crystal sits flush with the case edges, and the blue spinel cabochon on the crown adds a color accent that has been a signature across all collections from this house for decades. The Tank collection includes the Tank Francaise, Tank Americaine, and Tank Must in various sizes. If you prefer yellow gold with a more compact case, the Tank Solo W1018855 in yellow gold delivers the same rectangular DNA in a dressier metal.

What Sets It Apart

The 41mm format bridges the gap between compact vintage Tank references and the larger Tank Americaine. It provides enough vertical length to read as a modern watch rather than a retro accessory, while the narrow width ensures it never overwhelms the wrist. Roman numerals in a railroad-track minute ring maintain the classical dial language that Tank models have used for over a century. Sword-shaped blued steel hands add contrast against the silver background. The overall impression is of a watch that belongs equally in a boardroom and at a weekend dinner. This replica tank sta0040 41mm delivers the purest expression of the Tank silhouette for anyone who wants rectangular geometry without ornamental excess.
