The Harry Winston Histoires De Tourbillon 4
Today we've got the latest installment in Harry Winston's Histoire De Tourbillon series, a collection of watches meant to explore various directions in which the tourbillon can evolve. The Histoire De Tourbillon 4 features a unique triple-case tourbillon in an attempt to counteract the effects of gravity from all angles, as unlike the pocketwatches for which the tourbillon was invented, our wristwatches are constantly in motion.
Triple Cage Tourbillon
The tourbillon mechanism in this watch is one of the most complex out there. There are three concentric cages, each of which sits at a different angle in relation to the cage outside of it, and each of which rotates at a different speed. The outermost cage completes a revolution once every 300 seconds (5 minutes), the intermediate cage rotates once every 75 seconds, and the innermost cage spins once every 45 seconds.
Titanium Bridges and Plates
As part of it's push for accuracy, the Histoire de Tourbillon 4 incorporates sturdy-but-light titanium plates and bridges to support the lightweight (1.57 grams) tourbillon. The 345 part movement takes a top-notch watchmaker over 160 hours to construct and regulate, which is one reason why on 20 of these amazing watches will be made.
Available exclusively in 18k white gold with a Zalium caseband, the Histoires de Tourbillon 4 presents an interesting new take on a centuries old complication. For more information, please visit Harry Winston's website.
