The Visionary Behind the Brand: Understanding F.P. Journe

The journey of the F.P. Journe brand is inextricably linked to the vision and expertise of its founder, François-Paul Journe. Born in Marseille, France in 1957, his passion for horology ignited early in life, leading him to pursue formal training at the Paris watchmaking school, from which he graduated in 1976. Even before establishing his own manufacture, Journe was captivated by the intricacies of movement design, notably embarking on the creation of his first tourbillon pocket watch in 1978. This early dedication to mastering complex mechanisms laid the foundation for the philosophy that would define his brand: "Invenit et Fecit," Latin for "Invented and Made". This motto signifies that every F.P. Journe timepiece is conceived, designed, and meticulously crafted entirely in-house, a testament to the brand's commitment to horological authenticity and innovation.

Founded in Geneva, Switzerland in 1999, Montres Journe SA has remained fiercely independent, a rarity in an industry increasingly dominated by large conglomerates. This independence allows François-Paul Journe to maintain complete creative control over his creations, ensuring that each watch reflects his unique vision. While Chanel acquired a 20% stake in the company in 2018, the brand continues to operate autonomously, upholding its core values. F.P. Journe's dedication to pushing the boundaries of horological innovation and achieving exceptional chronometric performance has earned the brand numerous accolades, including the prestigious Aiguille d'Or at the Grand Prix d'Horlogerie de Genève an unprecedented three times. This recognition from the industry's highest authorities underscores the mastery and ingenuity that are hallmarks of every F.P. Journe timepiece.

The Octa Collection: Pioneering Automatic Excellence

The introduction of the Octa collection in 2001 marked a pivotal moment for F.P. Journe, representing his foray into the realm of self-winding movements. At a time when many independent watchmakers focused primarily on manual-winding mechanisms, Journe sought to create an automatic movement that would not compromise on precision or performance. The Octa calibre was revolutionary for its era, distinguished by its remarkable 160 hours of autonomy, a feat achieved through ingenious engineering. The design philosophy behind the Octa line centered on practicality, portability, and functionality for everyday wear, aiming to create a self-winding movement that offered both convenience and uncompromising accuracy. The Octa Lune, reference L, is a prominent model within this esteemed collection, showcasing the integration of a moon phase complication with the practicality of automatic winding.

Early Brass Movements (Calibre 1300) and Transitional Models

The earliest Octa Lune models, produced roughly between 2001 and 2004, were equipped with movements crafted from brass (Calibre 1300). These early examples hold a special significance for collectors due to their limited production and status as the foundation of the Octa line. Following this initial period, around 2004-2006, F.P. Journe transitioned to using movements made of 18k rose gold (Calibre 1300.3) as the standard. There exists a transitional period where some models featured early rose gold movements, often designated as calibre 1300-2. These transitional pieces are particularly rare and sought after, sometimes featuring the earlier bi-directional winding rotor and unique dial characteristics such as a two-tone silvery sub-dial and the inscription "Phases de Lune". Additionally, early models often had the year of manufacture of the case stamped on the case back, a detail later discontinued around mid-2005.

The decision to adopt 18k rose gold as the standard material for the movements across the F.P. Journe collection, including the Octa Lune Ref. L, elevated the brand's prestige and underscored its commitment to using precious metals in even the most functional components. This transition, which occurred around mid-2004, brought both aesthetic and material benefits, reinforcing the perception of F.P. Journe watches as true luxury items.

Introduction of Different Case Sizes and Dial Options

Over time, the Octa Lune Ref. L has been offered in various case sizes to accommodate different wrist sizes and preferences. The initial 38mm diameter was later complemented by a 40mm version, and eventually a larger 42mm case was introduced. The upsizing was primarily driven by client requests for improved legibility. In addition to case size variations, F.P. Journe has also introduced different dial options for the Octa Lune, including the sophisticated solid gold dials with embossed and polished numerals, and the distinctive "Havana" brown dial, which offers a unique aesthetic. The 38mm case size has since been discontinued, making those earlier models even more collectible.

The Modern Octa Lune Ref. L
