Arnold & Son HM Pietersite red gold 1LCDR.Z01A.C1506A

Ultra-slim elegance inspired by ocean storms

At Arnold & Son, every creation draws inspiration from the history of English timekeeping and the legacy of John Arnold, a leading figure in 18th-century precision watchmaking. With the HM Pietersite in red gold 750/1000, the maison unveils a timepiece of rare visual intensity, where mechanical finesse meets the poetic power of the elements.

Limited to just 18 pieces, this edition immediately stands out for its dial made of natural pietersite, a fascinating stone with shifting hues evoking the raging seas and stormy skies of the Cornish coast, the birthplace of John Arnold. Each dial features a unique pattern, giving every watch its own distinct identity.

The 39.5 mm 5N red gold 750/1000 case enhances this organic material with perfectly balanced proportions. At just 7.82 mm thick, the HM Pietersite exudes a discreet, contemporary elegance, designed for connoisseurs of refined haute horlogerie and exclusive ultra-thin watches.

Beneath this sleek silhouette beats the A&S1001 hand-wound in-house caliber. Visible through the sapphire caseback, this ultra-thin movement showcases Arnold & Son’s traditional craftsmanship through exceptionally meticulous finishes: sunburst Côtes de Genève, polished bevels, blued screws, and snailed wheels. Despite its slim profile of just 2.70 mm, it offers a remarkable power reserve of 90 hours.

Minimalist in its display of hours and minutes, the HM Pietersite prioritizes aesthetic purity and the nobility of its materials. Its ink-blue alligator strap harmoniously extends the deep hues of the dial, reinforcing the sophisticated and timeless character of this exclusive timepiece.

With this HM Pietersite Red Gold 750/1000, Arnold & Son presents a fine watchmaking timepiece that is as contemplative as it is technical, designed for collectors who appreciate the beauty of natural stones, English maritime history, and Swiss mechanical excellence.
