F.P. Journe Tourbillon Souverain Anniversaire Tokyo Ref. TT Titanium Grey Dial Limited Edition of 20

Twenty were made for the Tokyo boutique in 2007, the third watch in that anniversary series and the only tourbillon in it. All of them share the recipe the series has used since 2005, a polished titanium case, a rose gold crown and a ruthenium dial. None were sold anywhere else, and nothing comparable has been made since. Tokyo editions surface least often of any Journe limited series, and the tourbillon is the one people ask about.

Polished titanium at 40 mm, remarkably light for a tourbillon of any kind. A gold dial plate under ruthenium holds whitened guilloché silver registers, with the carriage exposed at the lower left. The dark ground makes the movement the brightest thing on the face. Titanium and a tourbillon is a pairing Journe has used almost nowhere else in fifty years of work, and it makes the watch far lighter than it looks.
