Macro Monday: Arnold and Son Time Pyramid

Photo by Atom Moore

This week we have an Atom Moore macro of the Arnold and Son Time Pyramid. Inspired by antique British skeleton clocks and the regulators created over two centuries ago by John and Roger Arnold, the new Arnold & Son Instrument Collection piece features a masterful example of elegant styling and technical precision: the original Time Pyramid wristwatch with a three dimensional construction that recalls designs of the past. The Instrument Collection focuses on pieces with sophisticated dial design, off-centered hour and minute indications, and a complex visual display.

Designed and developed by the company’s own La Chaux de Fonds workshops, the skeletonized mechanical calibre A&S1615 has a balance wheel at 12 o’clock, situated directly beneath the palette and the anchor wheel, the latter of which is shaped in an Arnold & Son majestic X form. At 6 o’clock there are two mainspring barrels supplying an amazing 90 hours power reserve, the power levels and transfer indicated by an arc of graduated dots printed under the top sapphire crystal. Meanwhile, the gear train runs vertically to connect the two barrels and balance wheel, endowing a pyramid structure.

The Time Pyramid features movement parts and indications built on three levels: subsidiary seconds dial on the bottom, hour indications on a sapphire crystal dial in the middle, and minute indications on a silver top ring. The effect is incredible detail and depth despite a thin movement (4.4 mm). The piece also features an elegant 18k red gold case, housing that tapers from top to bottom to fit snugly on the wearer’s wrist, and the Arnold & Son engraved crown logo artfully positioned at 6 o’clock. It’s an amazing amalgamation of elements, creating a piece that recalls the past while being truly unique.
