F.P. Journe Octa Perpétuelle Anniversaire Tokyo Ref. OP Titanium Grey Dial Limited Edition of 99

Ninety-nine of these went to the Tokyo boutique in 2009, the fourth watch in a series that started with a Chronomètre Souverain in 2005 and ended with a chronograph in 2024. Every edition used the same materials, a polished titanium case, a rose gold crown and a ruthenium dial, without exception. The perpetual calendar is the most complicated watch of the group, and the only one in the series to carry a full calendar at all.

Polished titanium at 40 mm, light for a calendar watch of this size. A gold dial plate under ruthenium carries whitened guilloché silver registers, with the calendar indications and the time laid out asymmetrically across it. Titanium and a perpetual calendar is a pairing Journe has used exactly once, and only for this one boutique. Nothing else in the collection puts a calendar this complete in a case this light.
