Arnold & Son @ Time Pyramid

 Arnold & Son unveils a totally new watch movement with unique architecture: the original Time Pyramid wristwatch. With a skeletonized pyramid-shaped movement seemingly floating between two sapphire crystals, the Time Pyramid is a masterful rendition of technical prowess and unparalleled elegance. This superbly engineered wristwatch is part of the brand’s Instrument Collection that combines instrument precision with classical styling. 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 Calibre 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.
The skeletonized caliber A&S1615 is built in a unique format, with balance wheel at twelve o’clock, situated directly beneath the palette and the anchor wheel (which is shaped in typical Arnold & Son’s majestic “X” form). At the opposite end of the movement, at six o’clock, lay two mainspring barrels that supply the hand-wound caliber with an amazing 80 hours of power reserve, and provide a more constant force to the wheel train.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. The power reserve hands indicate the reserve level via graduated dots (that are printed under the top sapphire crystal) in an arc format, and demonstrate how one barrel transfers energy to the second one when needed. Essentially, as the first barrel winds the second one, the power reserve indicator of the first barrel goes down, while the second one goes up making for an accurate and intriguing readout.As if all of this technical ingenuity were not enough, Arnold & Son continued to push the creative envelop in the making of this caliber with its placement of the escapement and seconds indicator at twelve o’clock, and with its three-dimensional construction that replicates the historic Arnold & Son regulators.
