Watches: Arnold & Son Time Pyramid Steel

By Thierry Ané on January 11, 2014

Since Citizen acquired La Joux-Perret and Arnorld & Son, I think it is safe to say that there is not a single timepiece presented by Arnold & Son that I have not found amazing. All the watches they unveiled in 2012 and 2013 were aesthetically refined and technically pioneering. And, according to what they told me, we can expect more extraordinary timepieces for this year’s Baselworld show.


For now, the brand unveils a steel version of a breathtaking timepiece presented in rose gold last year: the Time Pyramid. It gives me the opportunity to discuss an amazing see-through watch I haven’t reviewed yet.




Modelled after the English skeleton clocks of the 19th century, the Time Pyramid gets its name from its unique triangular layout. Seemingly floating between two sapphire crystals, the skeletonized pyramid-shaped movement of this watch is a marvel of symmetry.


Developed in-house, the manually-wound A&S1615 calibre features a vertical structure with the balance wheel at the top by 12 o’clock, followed by the linear gear train and two mainspring barrels on the opposite end at 6 o’clock. The movement is fitted with two power reserve indicators on either side of the linear gear train to display the energy level for each barrel separately with blued serpentine hands. When fully wound the watch delivers a power reserve of 90 hours.




In addition to demonstrating the brand’s ingenuity in watchmaking, this superbly engineered watch meets all the aesthetic standards one would expect from a High Horology piece: it showcases blued hands and screws, Côtes de Genève decorations, as well as hand-finished chamfered brides and high-polished edges.


For the new version, the perfectly polished 44.60 mm case has been crafted in stainless steel and is paired with a black alligator strap secured by a classic pin buckle. The beauty of the movement’s structure can also be admired through the sapphire case back. The view from there is surely as impressive as from the front!




I think that this watch has no equivalent in the watch industry. It is a truly remarkable piece of fine watchmaking both technically and aesthetically. At CHF 40,000, the Time Pyramid Rose Gold was already fairly priced. The use of steel on this version allowed the price tag to be reduced to CHF 29,500. It is really not that much considering the quality and originality of what you get. I think many watch lovers will appreciate the fact that the brand released this steel model…
