ARNOLD & SON TIME PYRAMID 1TPER.W01A.C153A

La Verticale du Temps , Time Pyramid 42.5 Red Gold

Arnold & Son redefines its iconic collections with timeless elegance, and the Time Pyramid is no exception. This timepiece, unique in its appearance and structure, is revisited with a new 42.5 mm case, enhanced by a blue aventurine glass caseback and white opal minute ring. Available in red gold (5N) and platinum (Pt950), this model embodies a refined contrast between precious materials and a symmetrical design of unparalleled depth. The Time Pyramid 42.5 plays with transparency and balance for an uncompromising aesthetic, asserting its distinctive character in the watchmaking world.

A Vertical Design Inspired by Tradition

Our conception of time is often linear or cyclical, but Arnold & Son propose an innovative approach with the Time Pyramid: a vertical alignment inspired by the British clocks of the 1830s. By structuring the movement’s components from top to bottom, the brand transcends horological conventions to offer a unique design expression.

Singular design and symmetry

With a pyramid-shaped skeleton movement visible in its 42.5 mm, 10.72 mm-thick case, the Time Pyramid also evokes an anchor, a nod to John Arnold’s naval history. Its 6 o’clock crown and baroque symmetry add a bold touch, reinforcing its originality.

Blue Aventurine glass caseback: a horological first

The back of the Time Pyramid features an exceptionally fine blue aventurine glass, a first in watchmaking. This glass, adorned with copper inclusions, comes from Venetian workshops renowned for their glassmaking expertise. Born of an accident in which copper shavings fell into the molten glass, the aventurine now sparkles like a celestial canvas, adding a poetic touch to this unique creation.

Explore the Time Pyramid 42.5 and discover how Arnold & Son reinvents the concept of time through innovative vertical alignment, captivating symmetry and exceptional materials.

Light
Arnold & Son uses glass as the backdrop for Time Pyramid. A canvas that lets light through when the watch is not on the wrist, revealing a play of transparency and color.

On the dial, the play of reflections is just as strong. Alternating gold and NAC (anthracite) finishes highlight the Côtes de Genève. The subtle appearance of the two barrel bridges reinforces the powerful, omnipresent impression of symmetry, Time Pyramid’s founding principle.

Structure
Time Pyramid’s movement is on full display. In the large opening of the case, the thin bezel reveals its mechanical layout. The screw balance, set at noon, sits majestically. Underneath, the gear train highlights the finishing touches: hand-crafted chamfering, satin-finishing and sunbursting of the wheels, colimaçonnage of the barrels, blued screws. Then the caliber structure splits in two under a ring of white opal, the signature stone of Arnold & Son’s eccentric dials.

On either side of this ringed dial, two power-reserve indicators respond to each other. They indicate the same information. They reflect the two barrels that, a few millimeters deeper, power the A&S1615 caliber. Entirely developed, machined, assembled and adjusted in-house, it beats for 90 hours without winding.
