The intricate, aesthetically appealing
details of the artisanally finished movement that is assembled twice can
be observed through the sapphire-crystal caseback. They include the
skeletonised and partially black-rhodiumed rotor with a centrifugal mass
in 950 platinum, the plates and bridges made of untreated German
silver, blued screws and the screwed gold chaton above the escape wheel.
When fully wound, the mainspring barrel delivers a maximum power
reserve of 50 hours. To guarantee high-rate accuracy regardless of
external factors, the balance operates at a frequency of 28,800
semi-oscillations per hour (4 hertz). It is regulated with four recessed
screws that are flush with the outside of the balance-wheel rim. This
design reduces turbulence despite the higher frequency. Together with
the freely oscillating balance spring made in-house, the minimised air
resistance has a positive impact on the movement’s rate accuracy and
energy efficiency. Contrary to other Lange calibres, the oscillation
system is held by a balance bridge secured at two points, instead of by a
cock. It is manually engraved with a wave pattern alluding to the water
resistance of the watch.
“With the ODYSSEUS, we laid
the foundation for our latest watch family in 2019, thus unfolding a
creative potential for us that we further tapped into by developing this
new model in honey gold,” explains Lange CEO Wilhelm Schmid. “In a
special way, the warm lustre emanating from this exceptional colour
combination reflects our ambition to never stand still.”
