Arnold & Son unveils a new reference of its
iconic Time Pyramid featuring 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
A&S1615 movement with unique skeletonised pyramid-shaped
architecture, was conceived, designed and developed in-house. The
movement A&S1615 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
Arnold & Son Time Pyramid offers a highly cohesive and
seductive blend of watchmaking feats that includes regulator,
skeleton, vertical linear movement, pyramid-placement of components
and multi-dimensional depth.
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. 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.
The two mainspring barrels supply the hand-wound calibre with an
amazing 90 hours of power reserve, and provide a more constant
force to the wheel train.
As with every esteemed Arnold & Son watch, the movement of
the Time Pyramid is magnificently hand decorated with
hand-chamfered brides and high-polished edges, Côtes de Genève,
circular satin-finished wheels and blued screws, all yielding a
striking masterpiece of decorative craftsmanship and brilliant
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.
