Arnold & Son, which was acquired by Citizen of Japan last year, has just announced the Time Pyramid at Baselworld 2013. A skeleton watch with the movement laid out in a triangular form, the Pyramid is inspired by the standing English skeleton clocks of the nineteenth century which had a similar movement shape.

Sandwiched between two sapphire crystals is the open-worked A&S 1615 movement, developed by La Joux-Perret, the sister company of Arnold & Son (and also now owned by Citizen). The movement runs from 12 to 6 o’clock with the balance wheel at the top, followed by the linear gear train, and the twin barrels at six o’clock, each with its own power reserve indicator. Together both barrels give a power reserve of 80 hours.

The Pyramid is in rose gold with a large, 44.6 mm case, which should allow for a panoramic view of the usual movement. The retail price is CHF39,960 which is equivalent to about USD42,100. – SJX
