The Revamped Arnold & Son Time Pyramid 42.5mm

A new 42.5mm size and an aventurine backdrop… Small updates but great results.

Originally unveiled in 2013, the Arnold & Son Time Pyramid is a splendid example of how a technical and functional movement can become a design element in its own right. With inner workings on full display and its handsome vertical architecture, the movement of the Time Pyramid is a polarizing mix of past maritime excellence, English skeleton clocks and historic Arnold & Son regulators. This year, the brand presents an updated version of its emblematic watch, with a more compact 42.5mm case, a white opal dial and an aventurine backdrop. Meet the updated Arnold & Son Time Pyramid.

Available either in 18k red gold or 950 platinum, the classically elegant case comes in a more compact 42.5mm diameter (versus 44.6mm in the past) and a slender profile of 10.72mm. If it has been slightly updated, the new case retains its design DNA and signature features, including the original position of the crown at 6 o’clock.

The skeletonized movement is shaped like a pyramid – hence the name of the watch. Its symmetrical, vertical architecture is structured with two barrels at its base, a gear train in a linear arrangement and a balance wheel at the top. The off-centred dial (for the hours and minutes) is a disc made of white opal punctuated by Roman numerals. Two different power reserve indicators with arrow-shaped hands are located on either side of the dial, one for each barrel. These are arranged in series to provide a more regular driving force. The hand-wound calibre A&S1615 runs at a frequency of 3Hz and can boast up to 90 hours of power reserve when fully wound. The main plate and bridges are dark grey NAC treated. The decoration includes Geneva stripes, hand-chamfering, circular-finished, gold-plated wheels and thermally blued-screws.

With this new take on the Time Pyramid, Arnold & Son has chosen to cast this architectural movement against a shimmering aventurine backdrop. It is also visible when looking at the back of the watch, as the caseback features a sapphire crystal protecting this aventurine disc. It allows the light to filter through when the watch is not being worn, creating intriguing plays of light. On the wrist, this original construction also prevents seeing your wrist and hairs through the movement, which many disliked in previous iterations of the Time Pyramid.

The new Arnold & Son Time Pyramid 42.5mm is released in two limited editions – 88 pieces in red gold and 38 pieces in platinum. The watch is worn on a hand-stitched blue alligator leather strap with black calfskin lining. The material of the pin buckle matches that of the case. The price is set at CHF 43,000 in red gold and CHF 54,900 in platinum.
