F. P. Journe Octa Reserve de Marche 18K Rose Gold Gray Dial

The F.P. Journe Octa Reserve de Marche in 18K rose gold with a gray dial is a refined testament to the brand’s pioneering automatic architecture. First introduced in the early 2000s as the maison’s inaugural self-winding model, this reference houses the integrated Calibre 1300 series, renowned for its five-day (120-hour) chronometric power reserve and instantaneous date mechanism. The 38 mm case, crafted in warm 18K rose gold, frames a subtle gray dial that offers a modern yet timeless aesthetic, while the off‑centre hours and minutes, small seconds at 4:30, large date, and power reserve indicator at 7:30 reflect Journe’s signature regulator layout. The movement’s 30.8 mm diameter and ultra‑thin 5.8–5.9 mm profile underscore the technical ingenuity of fitting multiple complications into a compact chassis. With a free‑sprung balance, micro‑flamed flat spring, and unidirectional winding rotor, the Calibre 1300 exemplifies high watchmaking discipline and efficiency. Although not a limited edition, this configuration remains rare and highly sought after, particularly among collectors who value its early brass‑movement heritage and the transition to 18K rose gold movements. The result is a sophisticated, historically significant timepiece that embodies both mechanical innovation and refined elegance. Excellent Condition with F. P. Journe box and papers dated 2015.
