This model was released for Baselworld 2017 and we shared our initial impressions here. Here, we will go hands-on together with the Arnold & Son DBG Skeleton and explore what makes this watch, aside from, you know… the dual balances.When it comes to evaluating the significance of this watch, I consider it crucial to look at the brand’s history. Arnold named this watch that the “No. 1,” starting a naming convention he’d use for his most significant timepieces moving forward.By 1772, an Arnold “No. 3” chronometer was aboard Captain Cook’s vessel when he set out for his second trip across the Pacific, along with Arnold chronometers goes on to accompany a number of other vital voyages over the following decades. His son, John Roger Arnold, started studying watchmaking beneath Abraham-Louis Breguet in 1792 and joined his father’s company four decades later. Breguet became a great friend of John Arnold and the two collaborated on balance designs, the overcoil balance spring, along with the tourbillon, although Arnold died in 1799 earlier this concept could be realized. To mourn his departure, Breguet introduced his son with the very first tourbillon escapement mounted in an Arnold pocket chronometer, which also conveys a personal inscription and is now displayed in the British Museum in London.
Arnold & Son has given its signature skeleton watch a solid gold guilloche case back that forms a decorative backdrop for the unusual pyramid-shaped movement.
A red gold case back, decorated with guilloche on both sides, highlights the unusual skeleton movement of the Arnold & Son Time Pyramid Guilloché. Originally introduced two years ago, the Time Pyramid is a skeleton watch with the movement modelled on 19th century English skeleton clocks. The Time Pyramid Guilloché is equipped with the same skeleton movement, but instead of a clear sapphire rear it has a red gold case case back. The front facing side is decorated with a sun ray guilloche, while the reverse is finished with a barleycorn engine turning of the sort common on pocket watches. The case is red gold and 44.6mm in diameter.
Case back aside the Time Pyramid Guilloché is identical to the original, with an in-house, hand-wound movement laid out like a pyramid. The escapement sits at the apex of the pyramid, with the gear train running linearly downwards to the twin barrels at four and seven o’clock. It has a 90 hour power reserve, along with twin power reserve indicators at three and nine o’clock for each barrel.
In recent years Arnold & Son has undergone a renaissance of sorts, consistently turning out interesting watches with proprietary movements like the Time Pyramid (also true for its newly launched brand Angelus). That thanks in part to La Joux-Perret, a movement constructor and manufacture, and along with Arnold & Son, owned by Citizen of Japan.
The Time Pyramid Guilloché is priced at SFr42,900.
