It took all of Piaget’s legendary daring, combined with its sovereign mastery of ultra-thin movements, to combine within a single watch two superimposed cases linked by a hinge. A highly original idea and a refined way of reading the time in two time zones, with a little touch of mystery reminiscent of so-called “secret” watches. The case done in 18kt white gold and uses Piaget caliber 450P movements with 18 jewels, beating at 21,600 bph.
