Journe is an exclusive watchmaker that produces less than a thousand timepieces annually. With exacting attention to detail, F.P. Journe's belief is that beauty begins from outside rather than from within - he commences his creative process by designing the dial and then arranging the internal mechanism accordingly. Each of the models in the Octa series possesses its own identity, although all share a common design and microengineering lineage. Upon its release, F.P. Journe offered the Octa Auto Lune in platinum and rose gold with either a red or white gold and silver dial in 40mm or 42mm cases. The calibre 1300.3 is presented in 18K rose gold and the movement boasts an impressive 120 hour power reserve. This is achieved through the large barrel which contains a 1 metre long mainspring.
