FOUR FLUSH
The Histoire de Tourbillon has been
a continuing project for Harry Winston
since 2009, but this year’s edition is the fi nal
instalment. Determined to close the chapter
with a bang, the brand has launched the
Histoire de Tourbillon 10, the world’s very
fi rst watch to contain four tourbillons with
four separate balances in a single movement.
Each cage rotates once every 36 seconds—
by using multiple regulating mechanisms is
to take advantage of the qualities of each
and harness their unique way of reacting
to gravity. Each will run at its own rate but
Harry Winston uses a complicated system of
three differentials to negate and average their
positions, which will then give an extremely
precise time. The calibre HW4702 needs
two pairs of fast-rotating barrels to provide a
55-hour power reserve.
