We are an authorised Arnold & Son retailer. To give the Ultrathin Tourbillon a unique and refined design, Arnold & Son has focused on materials and techniques that highlight the precious appearance of this finely honed tourbillon. Arnold & Son has used a manufacturing technique known as ‘Cosmic Grené’ on the dials. This name makes direct reference to stargazing, as stars are essential guides for navigating at sea along with marine chronometers (of which John Arnold was one of the largest and most reputable suppliers). The offset display and the tourbillon aperture echo the way in which information was arranged on John Arnold’s marine chronometers. If you have any further questions, please don't hesitate to contact us! PLEASE NOTE, PRICES ARE EXCLUDED VAT!
