In the early 1920s the United States was the largest export market for Swiss watches, and Vacheron Constantin produced a series of special references for American retailers catering to the tastes of the American market. In 1921, the Geneva manufacture made a small run of wristwatches with a distinctive layout: the cushion case was rotated 45°, placing the 12 at the top-right corner, the crown at 1 o'clock, and the small seconds at 4:30. The geometry was deliberate. A driver gripping a steering wheel with the watch on the left wrist could read the dial without rotating the wrist, because the 12 lined up with the forearm.
The driver's-watch format was a brief 1910s-1920s phenomenon, part of the broader transition from pocket watches to the wristwatch. Cartier's Tank (1917) and a handful of other Art Deco references came from the same impulse. The original Vacheron American 1921 was produced in very small numbers: fewer than two dozen documented examples exist, most in yellow or pink gold, typically 34-36mm cushion cases, and signed Vacheron & Constantin (with the ampersand, the pre-1970 signature). Original 1921-era examples now trade at CHF 100,000 to CHF 250,000+ at auction when they appear.
In 2008, as part of the Historiques collection (Vacheron Constantin's dedicated revival series), the manufacture released the modern Historiques American 1921. The reference faithfully reproduced the 1921 rotated-dial layout, preserving the crown at 1 o'clock, the 12 at the top-right corner, and the small seconds at 4:30. The case was sized up to a modern 40mm cushion in pink gold, and the movement was Vacheron's hand-wound Cal. 4400 AS (31mm diameter, 65-hour power reserve), fully finished to Hallmark of Geneva (Poinçon de Genève) standard with hand-guilloché decoration on the caseback side of the movement bridges.
For the centennial in 2021, Vacheron Constantin released two anniversary editions. The Historiques American 1921 Platinum (Ref. 4000S/000P-B781) was a 100-piece limited edition in 40mm platinum with a sandblasted silver dial and a hand-applied enamelled seconds ring. In 2022 a 36.5mm Rose Gold variant (Ref. 4000S/000R-B733) was added for smaller wrists, making the collection meaningfully more wearable for a wider range of buyers. Retail for the standard 40mm pink-gold Historiques American 1921 is approximately CHF 38,500; the 36.5mm rose-gold variant about CHF 35,000. The watch has become one of Vacheron's most recognisable modern designs, a piece that lives between the classical dress references (Patrimony, Traditionnelle, 222) and nothing else quite like it in the modern Swiss catalogue.
