F.P. Journe Octa Zodiaque Ref. Z Limited Series Platinum Slate Grey Dial

One hundred and fifty were made between 2004 and 2006, and no version of the Zodiaque has appeared since. The outer ring of the dial carries the months and their zodiac signs and steps around once a day, driven by the same mechanism as the large date, so the month and the sign both read at twelve. Journe has never built anything else like it, before or since, and the run closed almost twenty years ago.

The platinum case is 40 mm. The dial is slate gray solid white gold, matte and textured, with a silver chapter ring screwed down over it and the calendar ring turning at the edge. A large date sits at twelve and small seconds low on the face. It is the only Octa that shows anything about the sky, and the calendar needs correcting only once a year, which is the argument for an annual calendar.
