Arnold & Son Double Tourbillon 1DTAW.Z01A.C121W White Gold Jade Green White Opal Dial Piece Unique (2022)

The Double Tourbillon Jade represents Arnold & Son's mastery of rare stone dial integration celebrating brand's double tourbillon collection through dazzling green jade paired with delicate white opal sub-dials. Named after 18th-century English watchmaker John Arnold whose precision marine chronometers accompanied legendary navigators like James Cook, the watch pays homage to golden age of chronometry through two completely independent tourbillons regulating two independent time zones rather than conventional GMT additional hand approach. Wyoming-sourced "Apple Green" nephrite jade features subtle black veining adding depth and contrast making stone more precious while jade's cultural significance across Asian and Central American civilizations through sacred beliefs and protective rituals provides symbolic meaning unlike any other stone. Piece unique limited to one example in 18k white gold, dial plate expertly cut in clover shape with deep wells allowing both opal sub-dials and tourbillons to emerge full height complicating stone cutting and engraving stages demonstrating extraordinary craftsmanship.

The 43.5mm polished 18k white gold case features distinctive dual crowns at 2 o'clock and 7 o'clock independently adjusting time zone sub-dials and winding movement, domed sapphire crystal with anti-reflective coating both sides accommodating tourbillons' height, sapphire exhibition caseback revealing manual-winding Caliber A&S8513 comprising 42 jewels operating at 21,600 vph with twin barrels providing 90-hour power reserve. Jade dial features milky white opal sub-dials at 12 o'clock displaying local time with black Roman numerals and 6 o'clock showing reference time with Arabic numerals, both equipped with blued openworked arrow-tipped hands enabling minute-accurate adjustment accommodating unusual 15, 30, or 45-minute time zone offsets. Twin one-minute tourbillons positioned horizontally at 3 and 9 o'clock suspended by three-dimensional skeletonized cantilevered bridges in matching 18k white gold. Movement features radiant Côtes de Genève, circular-grained main plate, double-snailed barrels, sunray-brushed crown wheels, polished gold chatons, beveled mirror-polished screw heads. Black alligator leather strap with 18k white gold folding clasp, 30m water resistance.
