F.P. Journe Chronomètre Souverain Anniversaire Tokyo Ref. CS Titanium Grey Dial Limited Edition of 20

This was the first of the Tokyo anniversary watches, made in 2005 in a run of twenty, and it set the template every later edition followed: a polished titanium case, a rose gold crown, and a ruthenium-coated dial. Five more models have used that palette since, ending with the Chronographe FB in 2024. None of the twenty were sold anywhere but the Tokyo boutique, and the anniversary series has never once been reissued in any form since.

Polished titanium at 40 mm, light on the wrist in a way no platinum or gold Chronomètre Souverain can be, with the crown in rose gold as the single warm detail. The dial is guilloché silver under ruthenium, a dark gray ground that keeps the cut pattern visible underneath. It is the only titanium version of the model Journe has made, and it remains the lightest formal watch in the entire collection.
