Arnold & Son DTE Double Tourbillon Escapement – Ultra-Thin Dual Time Masterpiece

The Arnold & Son DTE Double Tourbillon, introduced in 2015, is an extraordinary example of ultra-thin haute horlogerie. With a case just 8.35 mm thick, it houses two independent tourbillon escapements, making it one of the thinnest dual tourbillon watches ever created. This innovative design allows collectors to admire mechanical mastery and aesthetic balance in one stunning timepiece.

Dual Time and Dial Excellence

The Arnold & Son DTE features a silvered dial with Côtes de Genève finishing and dual independent time displays: a Roman numeral subdial at 12 o’clock and an Arabic numeral subdial at 6 o’clock. This allows the wearer to track the time in two different cities simultaneously. The blued steel hands contrast beautifully against the white lacquered backgrounds, providing perfect legibility.

Caliber A&S8513 – Dual Tourbillon Power

The movement inside, Caliber A&S8513, is a hand-wound mechanism featuring two tourbillon carriages connected by a gold bridge. Each tourbillon has its own escapement and gear train, yet both are powered by a single mainspring barrel. The movement offers an impressive 90-hour power reserve and beats at 21,600 vibrations per hour, delivering precise timekeeping across its full duration.

Case, Materials, and Collector Appeal

The watch is housed in a 43.5 mm 18K white gold case, offering a substantial wrist presence while maintaining a slim and elegant profile. Limited to 28 pieces, the DTE is priced at USD 210,000 and comes with an alligator leather strap with 18K white gold buckle. Its combination of dual time functionality and the visually captivating tourbillon complication makes it a sought-after masterpiece for collectors and haute horlogerie enthusiasts.
