A rare Breguet 1801-2001 anniversary model wristwatch will carry an estimate of $60,000-80,000 to Christie's Important Watches auction in Dubai on October 29.
Made to mark the 200th anniversary of the invention of the tourbillon by company founder Abraham-Louis Breguet, the watch features an 18k pink gold half hunter case and an eccentric silver engine-turned time display - revealed by pressing a button on the crown that lifts the hinged cover.
A one-minute tourbillon carriage is visible through the dial.
A Horologer De La Marine model, also made by Breguet and featuring an 18k pink gold case, is offered with an identical estimate.
It features a grey engine-turned dial and an aperture for a visible titanium one minute tourbillon carriage.
