The watch is available in two sizes — either 40 mm or 42 mm in diameter — in either rose-gold case with rose-gold dial or platinum case with white gold dial. The movement, Caliber 1510, is manual-wound and, as in other Journe timepieces, made of 18k rose gold.
The dial of the Chronomètre Optimum features an off-center hours and minutes display, a small-seconds subdial at 9 o’clock, and a hand-type power reserve indicator at 6 o’clock. The movement holds a power reserve of 70 hours.
Prices are $90,800 for the platinum model in 40-mm case; $92,400 for platinum in 42-mm case; $86,400 for rose-gold in 40-mm case; and $88,800 for rose gold in 42-mm case. Journe says that the Chronomètre Optimum will not be restricted to a set number of pieces, but production is, of course, limited to the number of pieces that his small, boutique company can make per year in its Geneva workshop. Journe takes great pride in the watch, which represents a pinnacle in his quest for ultimate timekeeping precision. “My watchmaking philosophy,” he says, “is to make watches that will still work in 200 years.”

It would be very appropriate if they also published the timekeeping precision results.
