At Baselworld next week, Arnold & Son will officially launch the Time Pyramid, which is inspired by vintage regulators and antique British skeleton clocks. The movement, caliber A&S1615, was designed and produced in-house in the brand’s La Chaux-de-Fonds workshops. The movement is hand wound, has 27 jewels, beats at 21,6000 vph (3Hz) and has an 80-hour power reserve.

The large 37 mm diameter skeletonized movement is made of nickel-silver and is rhodium treated. The bridges are chamfered with polished edges, Côtes de Genève, circular satin-finished wheels, blued screws skeletonized nickel-silver movement, rhodium treated with Haute Horlogerie finish: manually chamfered bridges with polished edges, Côtes de Genève, circular satin-finished wheels and blued screws.

“Inspired by the regulators created by John and Roger Arnold over two hundred years ago, and by antique British skeleton clocks, the new Arnold & Son exclusive mechanical Caliber A&S1615 was conceived of, designed and developed in-house at the company’s La Chaux-de-Fonds workshops, Switzerland.

To reflect the spirit of the brand’s rich history, yet with a vigilant eye to the future, Arnold & Son has created a highly cohesive and seductive blend of watchmaking feats in this timepiece that includes regulator, skeleton, vertical linear movement, pyramid placement of components and multi-dimensional depth. The Time Pyramid is part of the Instrument Collection, wherein timepieces are easily identified by their sophisticated dial designs, off-centered hours and minutes indication and visual display of complexities.”


Functions include hours, minutes, seconds and a double power reserve indication. The dial is in sapphire with a circular satin-finished dial frame with chamfered and polished edge. The case is in 18K red gold and is 44.6 mm in diameter with a cambered sapphire with glareproofing on both sides and a see-through case back. Hand-stitched brown or black alligator leather. Water-resistance is 30 meters. (Ref. 1TPAR.S01A.C124A)
