Launched around 1993 to mark the 60th anniversary of the Reverso, the reference 270.2.68 Reverso Tourbillon was a limited edition of 500 pieces in 18k rose gold, each numbered within the series. The rectangular reversible case shows a silvered guilloché dial on the front, while the reverse has a sapphire crystal revealing the tourbillon carriage and a power reserve indication. It is powered by the manual-wind calibre 828 with 27 jewels, in a case of roughly 42 x 26 mm.
