The tourbillon complication was invited and
patented by Abraham Louis Breguet in
1801, to ensure accurate time keeping and
to counter the effect of gravity on pocket
watches. Today, there are many iterations
and variations of this iconic complication.
The present example by Jaeger LeCoultre,
housed in a skeletonized glass case, allows
the viewer to marvel the complication in
action, whilst reading the time.

The design of the present clock is focused
on incorporating thinner movements.
The movement is manufactured in a
miniaturized form, featuring a free-end
escape when and a free-end palette fork.
The assembly allows the escape wheel
pinion to engage with the tourbillon's
stationary wheel which reduces the risk
of damage. The movement also features
ball bearings. The flying components,
such as the palette fork and escape
wheel, make the overall construction very
unusual. We believe this clock may have
been an early working model that Jaeger
may have used as a study for its early 'Da
Vinci' tourbillons. The movement is based
on the caliber 210, and the caliber 250
was the improved version of the 210 and
introduced to the market in 1979.
