Roger Dubuis
Excalibur Collection

Welcome to the 2017 SIHH where Roger Dubuis
is taking a quantum leap into the next Excalibur
aeon offering an unprecedented vision of a sphere
where the magnitude of the aesthetic aftershocks
is truly off the scale. And in addition to taking to
the fast track with the introduction of a range of
stunning world premieres, the Geneva show will
also provide the launch platform for a brandnew
alliance with Pirelli. Excalibur Quatuor Cobalt Mi-
cromelt: When it comes to progressive complica-
tions, the hand-wound 590-part RD101 Quatuor
movement – beating at a frequency of 4×4 Hz
(115,200 vph) with its four sprung balances and
five differentials – is as progressive as they get…
Instantly achieving what the tourbillon takes a full
minute to accomplish – namely compensating for
the rate variations caused by the effects of gravity
on a watch, in 2017 it welcomes its very own di-
sruptive material in the form of cobalt chrome. This
high-performance alloy clothing the 48 mm-dia-
meter case, bezel, case-back and crown is produ-
ced using the extremely exclusive Micromelt te-
chnology that represents just 0.1% of worldwide
metallurgy.
