This model revisits the flying Tourbillon which Bovet introduced in 2015 as part of a completely reworked movement with a gigantic 10-day power reserve, provided by a single barrel. Three time zones are displayed in an original fashion. Local time is shown by central hour and minute hands, while a dome at 12 o'clock indicates day and night. The other two time zones, which the wearer selects, are relayed by 24-hour hands that sweep two hemispherical domes that represent the Earth. An aperture above each dome indicates the reference city for each of these two time zones. This impressive calibre is housed inside the Amadeo convertible case. As a reversible watch, hours and minutes, synchronised to local time, are displayed on the back, together with a power-reserve indicator. The patented double-sided flying tourbillon presides at 6 o'clock. Only 60 movements will be made, proposed in a red gold, white gold or platinum case.
