To commemorate the 5th anniversary of the F.P. Journe Tokyo boutique, the atelier launched the Tokyo Anniversaire series: five models, including this Octa Perpétuelle. Limited to a 99-piece production, not only is the Octa Perpétuelle the singular new complication of the Tokyo Anniversaire series, it is also unique to this collection, making this timepiece particularly rare. The very first perpetual calendar made by F.P. Journe, this timepiece also features a retrograde date function with the leap year indicated in a sub-aperture. A quick-set function allows the wearer to easily adjust the months annually and then lock it, preventing any accidental change. Perfect for any collector looking to add a rare yet very wearable complicated piece by the now famed independent. Bidding in the Fine Watches sale at #SothebysNewYork is open now through 13 September. Discover the full catalogue through our link in bio. #SothebysWatches #FPJourne
