Time Pyramid Tourbillon

The Time Pyramid Tourbillon presents a cohesive combination of watchmaking feats organized in a pyramidal architecture. The skeletonised calibre A&S8615 pays tribute to the John Arnold’s regulators with their distinctive hours, minutes and seconds on different axes. The movement is built on three levels. The tourbillon and the two power reserve indicators are superposed by a sapphire crystal dial indicating the hours itself, crowned with a rhodium plated ring for the minutes. This exclusive construction offers a lively-look and three-dimensional face to the timepiece and, to further enhance the balance and symmetry, the crown is positioned at six o’clock.

The gear train runs vertically in a linear arrangement connecting the two barrels at six o’clock to the tourbillon escapement at twelve o’clock, giving the movement its pyramidal architecture. The bridges are designed so that all the wheels, the two mainspring barrels, the escapement and balance wheel are all visible from the dial side.

Besides the off-centred hours and minutes, seconds are on the tourbillon and the two power reserve indicators are on each side of the linear gear train. The blued steel hands indicating these power reserves artfully demonstrate how the right barrel takes over when the left barrel reaches a limited power and thus, to maintain an optimum and accurate functioning. The two serially set up barrels supply the in-house manufactured calibre with a total of 90-hour power reserve and provide a more regular force to the wheel train.

To meet with Arnold & Son finishing standards, the movement of the Time Pyramid Tourbillon is decorated with chamfered bridges, polished edges and Côtes de Genève while the main plate is satin-finished, the A&S three-spoke wheels chamfered, the edges polished, and the screws blued. The top bridge and cage plate of the tourbillon are circular satin-finished, chamfered and mirror-polished by hand.

The Time Pyramid Tourbillon is housed in a 44.6 mm diameter 18-karat red gold or stainless steel case and adorned with a hand-stitched alligator strap.

  About the name

The Time Pyramid is inspired by the regulators created by John and Roger Arnold over two hundred years ago and by antique British skeleton clocks with their recognizable vertical construction and cone-shaped chain and fusee system.

Arnold & Son présente un modèle unique de son emblématique Time Pyramid pour l’Only Watch 2017 dont la vente sera menée par Christie’s lors de la vente aux enchères Only Watch à Genève.

Inspiré par les régulateurs créés par John et Roger Arnold il y a plus de deux cents ans et par des horloges britanniques squelettées, cette pièce offre un mélange comprenant un régulateur, une montre squelette, un mouvement linéaire vertical avec placement pyramidal des composants.

(adsbygoogle = window.adsbygoogle || []).push({});

Pour le modèle Time Pyramid Only Watch 2017, le boîtier en acier inoxydable est livré avec un traitement DLC noir tandis que le calibre symétrique squeletté A&S1615 reçoit un revêtement A-DLC noir, offrant ainsi un contraste frappant entre la finition traditionnelle de haute horlogerie et la décoration appliquée à la main.

En outre, on notera les accents rouges appliqués à plusieurs composants de la montre : les deux indicateurs de réserve de marche (un par barillet), les aiguilles des heures et des minutes, ainsi que sur les chiffres romains sur le cadran en saphir. La touche finale de rouge se retrouve dans les coutures du bracelet en alligator anthracite.

La pièce unique Arnold & Son Time Pyramid Only Watch 2017 sera vendue à l’enchère de charité Only Watch 2017 à Genève le samedi 11 novembre au Four Seasons Hotel des Bergues.
