Luxury watch and jewellery brand Harry Winston has launched the fourth edition of the longstanding Histoire de Tourbillon timepiece.
The new watch incorporates modern touches that bring the historical piece into the 21st century.
There are three individual cages on the dial, which rotate at different speeds and angles, all set within an 18-carat white gold case.
Other features include 18-carat gold screws in the rim and an extended power reserve of 50 hours.
Limited to 20 pieces, the new Histoire de Tourbillon timepiece is sure to be one of the most talked-about additions to the Baselworld catalogue.
