Arnold & Son Announces the Ultrathin Tourbillon Skeleton

The Ultrathin Tourbillon Skeleton’s elegant curves and expansive open-worked design are further accentuated by its remarkably slim profile. The redesigned case, measuring 41.5mm in diameter and a mere 8.4mm thick, provides a breathtaking showcase for the flying tourbillon movement. Limited to two exclusive series of 28 pieces, each in red gold or platinum, this collection embodies the pinnacle of watchmaking refinement.

Arnold & Son continues to impress with the Ultrathin Tourbillon. Within its sleek case lies the meticulously crafted A&S8320 calibre, its intricate details laid bare. Each watch is a testament to precision and craftsmanship, limited to a production run of just 28 pieces, available in either luxurious red gold or platinum. The flying tourbillon at the heart of this timepiece exemplifies Arnold & Son’s dedication to excellence.

This remarkable movement boasts a remarkably slim profile of only 3.3mm, making it one of the thinnest skeletonized tourbillons on the market. Including a variable-inertia balance ensures exceptional precision in this meticulously crafted one-minute flying tourbillon.

RADIATING ORIGINALITY
Skeletonization takes on a new dimension in the Ultrathin Tourbillon Skeleton. Its purpose exceeds mere mechanics, revealing a dynamic interplay of curves and angles highlighted by a unique finish. The Red Gold and Platinum models showcase bridges meticulously adorned with radiating Côtes de Genève stripes and finished in a luxurious rose-gold PVD (4N). This same finish extends to the flange, framing the calibre and boldly showcasing the Arnold & Son signature at 6 o’clock. The off-centred white opal dial stands in stark, elegant contrast.

GOLDEN CARRIAGE
The heart of the Ultrathin Tourbillon Skeleton is the A&S8320 calibre, a masterpiece of architecture and precision. Its ingenious flying tourbillon design eliminates the upper bridge to achieve extraordinary thinness. Precision remains paramount, with a variable-inertia balance featuring inertia blocks ensuring superior timekeeping stability. The delicate triangular carriage, supported by a double-arrow counterpoise, completes each minute’s graceful rotation. The arrowhead on the escape wheel staff doubles as a second indicator.

PERFORMANCE RESERVE
The masterful redesign of the tourbillon carriage and regulating organ unlocks an impressive 100-hour power reserve within the A&S8320 calibre. While exceeding the capabilities of many standard tourbillons, especially those of comparable thinness, this extended power reserve aligns perfectly with the exceptional level of performance consistently delivered by Arnold & Son timepieces.
