Arnold & Son unveils a new reference of its iconic Time Pyramid. This fascinating skeleton watch was first introduced in 2013 in a pink gold edition and then followed in 2014 by a stainless steel version. This year’s version features the hand-chamfered A&S1615 calibre, housed in a 18-carat red gold case with a new case back beautifully decorated with a guilloché pattern on both sides.
The skeletonised calibre A&S1615 follows the original regulators from the brand with its component positioning and detailed 3D visual appeal. Movement parts and watch indications are built on three levels, with the subsidiary seconds dial on the bottom, the hour indications on a sapphire crystal dial in the middle level, and a silver top ring for the minutes indication. While the movement is extremely thin – at just 4.4 mm – the multiple levels bring amazing depth and detail to the watch. To further enhance the balance and symmetry of the Time Pyramid, the crown (with Arnold & Son’s engraved logo) is artfully positioned at six o’clock.
The gear train runs vertically in a linear format connecting the two barrels at six o’clock to the balance wheel at twelve o’clock, and endowing the movement with its pyramid structure. The bridges are designed so that all of the wheels, the two mainspring barrels, the escapement and balance wheel are all magnificently visible from the dial side. Additionally, the movement is fitted with two power reserve indicators – one each on either side of the linear gear train – to display the energy level for each barrel separately.
Each Time Pyramid wristwatch measures 44.6 mm in diameter in its classically elegant 18-carat red gold case with a case back beautifully decorated with a guilloché pattern on both sides. Viewed from the side, the housing is stepped and tapers from top to bottom, the widest section accommodating the extra-large glass with the lower part narrowing to fit snugly on the wrist. Each is finished with an exquisite hand-stitched alligator strap.
This superbly engineered wristwatch is part of the brand’s Instrument Collection that combines instrument precision with classical styling.
