Its broad dial fully exploits the deep black of the  onyx, enhancing the sweep of the regulating organ at 6 o’clock. \u003c\/p\u003e\u003cp\u003eWhen John Arnold began his career in London in 1762, only a  handful of leading watchmakers – including George Graham, Thomas Mudge  and John Harrison – used pierced rubies to reduce friction at the pivots  of the final wheels of the gear train and the balance. Long a closely  guarded secret among English master watchmakers, John Arnold also  employed this savoir-faire in jewels in the escapements of his marine  chronometers and deck watches. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommemorating expertise\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eInvested in the working of ornamental stones since its founding,  Arnold \u0026amp; Son continues this tradition today by adorning select  creations with fine and precious stones. For this edition of the  Ultrathin Tourbillon Onyx, the Maison has chosen a 41.5 mm case with  softly rounded contours, available in 18-carat 5N red gold or 950  platinum. It is framed by a slim bezel and fitted with a sapphire  crystal, revealing a generously proportioned main dial. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShades of black\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eThe main part of the dial is fashioned from a finely polished  disc of genuine onyx. A variety of agate from the large chalcedony  family, this stone is defined by its dark, intense and enigmatic hue. It  was selected for its aura of mysterious elegance, which emphasises the  refined character of the Ultrathin Tourbillon. The concave  hours-and-minutes sub-dial is also crafted from black onyx. True to its  reputation for inventive use of fine stones, Arnold \u0026amp; Son breaks new  ground here, exploring previously uncharted territory: for the first  time in watchmaking, onyx is given a matt satin finish. Bold and complex  in its execution, this treatment reveals a subtle interplay of  materials and reaffirms the Maison’s expertise in the art of working  with stone, pushing the boundaries of traditional mineral dial design. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe magic of contrast\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eOnyx has been associated with inner strength, courage and  self-mastery since antiquity. Greek and Roman civilisations considered  it a talisman, believing in its protective powers. Valued over the  centuries, onyx has been widely used in jewellery, seals and ceremonial  objects, where it has long symbolised power, authority and discernment.  Rich in symbolism, it reveals its full magic here, showcasing the  hand-bevelled cage of the flying tourbillon through a wide circular  aperture at 6 o’clock in the thin stone disc. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA heart of gold\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eA truly refined movement was required to bring the Ultrathin  Tourbillon Onyx – presented in 18-carat 5N red gold or 950 platinum – to  life. At just 2.97 mm thick, the in-house A\u0026amp;S8300 manual-winding  calibre is among the thinnest available today and fully meets the  demands of this haute horlogerie timepiece. Visible through the sapphire  crystal case back, the movement reveals its full sophistication. Its 32  mm diameter showcases exemplary finishing: radiating Côtes de Genève,  chamfering, snailing on the two-barrel ratchet wheels, and polished,  blued and chamfered screws. The flying tourbillon bridge is crafted in  3N yellow gold and hand-engraved with plant motifs inspired by those  that adorned the balance cocks of John Arnold’s pocket watches. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA tale worth spinning\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eThe large, delicate and elegant cage of the flying tourbillon  tells a story through symbols. The stylised sextant evokes John Arnold’s  pivotal role in advancing the calculation of longitude with his marine  chronometers. And the anchor-shaped counterweight – whose central tip  serves as a reference for reading the seconds as the cage completes its  one-minute rotation – recalls the iconic designs of the renowned English  watchmaker. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAlways moving forward\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eTo ensure optimal performance for the Ultrathin Tourbillon Onyx,  Arnold \u0026amp; Son has reworked several components of the A\u0026amp;S8300  calibre. Among the key developments are the integration of a  variable-inertia balance, refinements to the regulating organ, and  modifications to the tourbillon cage. These changes significantly  increase the power reserve, now extended to 100 hours when the watch,  water-resistant to 30 metres, is fully wound. This enhancement further  reinforces the exceptional character of the ultra-thin tourbillon  timepiece. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA celebration of contrasts\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003ePresented on an alligator leather strap lined with the same  material and secured by a folding clasp, the Ultrathin Tourbillon Onyx –  produced in eight pieces in gold and eight in platinum – embodies a  timeless elegance, elevated by understated sophistication.\u003c\/p\u003e","brand":"Arnold \u0026 Son","offers":[{"title":"Default Title","offer_id":47168044892331,"sku":"1UTBX.Z03A.C1375C","price":109000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/2783\/3515\/files\/5696588611.jpg?v=1780440424","url":"https:\/\/www.exquisitetimepieces.com\/products\/arnold-son-ultrathin-tourbillon-platinum-onyx-1utbxz03ac1375c","provider":"Exquisite Timepieces","version":"1.0","type":"link"}
