The DTE (Double Tourbillon Escapement), introduced by Arnold & Son in 2015, represents an extraordinary achievement in ultra-thin haute horlogerie. Within a case measuring just 8.35 mm thick, the brand has succeeded in housing two independent tourbillon escapement systems, making it one of the thinnest dual tourbillon watches ever created.
The silvered dial, decorated with Côtes de Genève finishing, features two independent time displays: a Roman numeral subdial at 12 o’clock and an Arabic numeral subdial at 6 o’clock, allowing the wearer to read the time in two different cities simultaneously. The blued steel hour and minute hands stand out beautifully against the white lacquered backgrounds, ensuring superb legibility.The two tourbillon carriages, connected by a gold bridge, each possess their own escapement and gear train, both drawing power from a single mainspring barrel. The in-house Caliber A&S8513 is a hand-wound movement that delivers an impressive 90-hour power reserve — an exceptional feat for a dual timepiece of this complexity.
The watch features a 43.5 mm white gold case, offering a substantial wrist presence while maintaining a slim and elegant profile that ensures excellent comfort.
Combining the tourbillon, one of watchmaking’s most visually captivating complications, with dual time indication, one of the most practical, the DTE Double Tourbillon Escapement achieves a remarkable balance of technical mastery and aesthetic harmony.
Limited to 28 pieces, it is priced at USD 210,000.
