Tank Louis Cartier L model Platinum Ruby Crown WGTA0373 | 2026 Mint Full Set

The Story

Created by Louis Cartier in 1917 and inspired by the geometric purity of military tanks on the Western Front, the Tank is horology's most iconic rectangular wristwatch. The Tank Louis Cartier (Tank LC) represents the purest, most refined expression of the design, defined by soft, rounded brancards (case sides). Reference WGTA0373 is the pinnacle of the modern line: cast in solid 950 Platinum. Cartier reserves the ruby cabochon set into the beaded winding crown exclusively for its platinum creations, providing an immediate visual signifier of precious-metal rarity.

The Craft: 950 Platinum Architecture & Automatic Calibre 1847 MC

The Extra-Large (XL) case is forged from dense, high-luster solid 950 platinum, featuring polished rounded brancards paired with the collection's distinctive beaded crown set with a genuine ruby cabochon.

The silver dial is decorated with a radiating flinqué sunburst guilloché pattern that plays with ambient light. The design showcases Cartier’s historic hallmarks: bold black Roman numerals, the inner "chemin de fer" railway minute track, Cartier secret signature at 7 o’clock, and central sword-shaped blued-steel hands with a blued central seconds hand.

Beneath the solid platinum caseback beats the Manufacture Cartier Calibre 1847 MC. Operating at 28,800 vph with an approximate 42-hour power reserve, this self-winding movement delivers automatic convenience while preserving the refined, slender profile on the wrist.
