Made between 2002 and 2005, the F.P. Journe Ruthenium Collection comprises five early brass movement timepieces with each released as a limited edition of 99 pieces. Among these, the Octa Chronographe stands out as a particularly special piece, being the world's first automatic flyback chronometer chronograph with an oversized date window. It also features a larger 40mm case diameter, deviating from the traditional 38mm size of most of its predecessors, giving it a more modern appeal and presence on the wrist.

Ruthenium, though uncommon in watchmaking, is a rare inert metal closely related to the platinum family in the periodic table. It is highly valued in aerospace engineering for its natural resistance to oxidation and exceptional hardness. In the Ruthenium Collection, the brass movements of each timepiece are fully coated with a light-absorbing ruthenium coating. Similarly, the white gold dial is specially coated with the same treatment, while still preserving the remarkable sheen and luster found in F.P. Journe's early solid gold dials. These dials often exhibit beautiful variations of patina, and in the case of the Ruthenium Collection, the tarnish-free darkness of the ruthenium coating enhances the glimmer of the underlying gold dial.

The present Octa Chronographe numbered 52 is in well-preserved overall condition and comes complete with its certificate and accessories. This adds to its desirability and makes it a highly collectible piece for enthusiasts of F.P. Journe watches.
