The three-dimensional, openwork movement and dial of the Nebula
offer views into the very heart of the in-house manufacture
calibre. Two mainspring barrels providing a healthy 90 hours power
reserve at the top, find near-mirror symmetry with the small
seconds display and dial-side balance below.
It has long been a proven fact that when we consider a person's
face "beautiful" we are actually noticing facial symmetry because
the human brain finds beauty in symmetry. And it's not just the
visually balanced faces of people that we find attractive, but
symmetrical faces in general - including those of timepieces. This
goes a long way toward explaining the watch lover's strong
attraction to the refined Arnold & Son Nebula, which is
symmetrical not only horizontally and vertically but also front and
Besides the evident careful attention to balance, the powerful
allure of the Nebula also derives from the meticulously calculated
proportions and ratios of diameter versus height and the 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. The "dial" actually acts
as a bridge in supporting some of the intricate gearing.
The movement bridges − there are no less than ten in this
complex calibre, compared to four in a standard watch − form the
The name "Nebula" (Latin for "cloud") was selected because with
its bridges distinctively radiating from the perimeter of the dial
toward the centre, the sculptural movement looks like an inverted,
exploded star. Nebulae, an astronomical term describing a cloud of
cosmic gas and dust, are formed from the debris of exploding stars
and constitute the regions in our universe in which new stars are
born . . . new stars like the Nebula.
Highly legible central hours and minutes rotate above the
movement that was conceived and developed from the outset to be
openwork rather than have superfluous material skeletonized as an
afterthought. 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 below. 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 English movement architecture.
Not only is all of the movement visible and highly decorated,
all of the most technically interesting and animated mechanisms,
including the barrels, gear train, balance and escapement, and
winding mechanism, can be appreciated from the dial side without
having to turn the timepiece over.
But that's not to say the underside of the movement is something
to be overlooked. The view through the display back reveals even
more of the superlatively hand-finished movement, with its
skeletonized and chamfered main plate with polished edges, solid
18-karat gold chatons and gears featuring polished chamfers.
The Nebula is available in a 41.50 mm, 5N red gold or stainless
steel case, with a sapphire crystal display back for viewing the
superbly hand-finished movement.
