Arnold & Son reinterprets its emblematic, symmetrical
skeleton Nebula in new proportions.
The three-dimensional, openwork movement and dial of the Nebula
offer views into the very heart of the in-house manufacture
calibre. Its gold case has been reinvented in a 38 mm diameter,
magnifying the hypnotic micro-mechanical spectacle of the
Besides the careful attention to equilibrium, the powerful
allure of the Nebula also derives from the calculated proportions
and ratios of diameter versus height, size and placement of every
gear and wheel. Rather than being an assembly of disparate
components - case, dial, and movement - Nebula was designed from
the ground up to be completely holistic, with all components
blending harmoniously into one. For instance, no less than ten
bridges of this complex calibre form the dial.
Highly legible hours and minutes rotate above the movement
conceived and developed from the outset to be open rather than have
superfluous material skeletonized as an afterthought. The revised
sloping chapter ring and faceted golden indexes complete the
impactful visual effect of the Nebula 38mm.
The balanced construction of A&S 5101 calibre - horizontally
and vertically symmetrical, both front and back - explains the
watch lovers' strong attraction to the refined Nebula 38mm. On the
dial side, symmetry at top to bottom is provided by the two
mainspring barrels, which provide a very healthy 90 hours of power
above, and small seconds plus the oscillating balance wheel
Seven of the skeletonized and chamfered triangular bridges with
polished edges fixed around the perimeter of the movement and
radiating inward, offer a contemporary take on traditional
Not only is all of the movement visible and highly decorated -
barrels, gear train, balance and escapement, and winding mechanism
- can be appreciated from the dial side. But that's not to
say the underside of the movement is something to be
The view through the display back reveals even more finishing,
with skeletonized and chamfered main plate with polished edges,
solid 18-karat gold settings and gears featuring polished chamfers.
The Nebula 38mm is available in a red gold case, in a limited
edition of 50.
About the name
"Nebula" (Latin for "cloud") refers to the astronomical term
describing a giant cloud of dust and gas thrown out by the
explosion of a dying star. Nebulae are also regions where new stars
are beginning to form. The seven bridges on the dial side radiate
from the centre toward the perimeter and give an impression of
stellar explosion to the sculptural movement.
