F.P.Journe LineSport Automatique Réserve 18K 6N Gold — Guilloché Grey Dial | Ref. 1300.3

The lineSport Automatique Réserve stands as one of F.P.Journe's most audacious propositions: a sports watch constructed entirely in 18-karat 6N gold, defying the convention that haute horlogerie must retreat to the study when the wearer steps outdoors. Conceived as part of the LineSport collection, this 44 mm piece carries the full suite of Journe's signature complications within a form language designed for physical engagement—bold proportions, secured crown, open case back revealing the Calibre 1300.3 in all its solid-gold movement architecture.

The Calibre 1300.3 is an automatic movement of exceptional ambition, delivering a power reserve of 160 hours—six and a half days—from a single winding cycle. This reserve is displayed on the dial itself, alongside date, day/night indicator, and small seconds, creating an information hierarchy that rewards the engaged wearer without overwhelming the composition. The movement plates and bridges are, as with every Journe calibre, crafted from solid 18-karat rose gold—a commitment to the metal's thermal stability and visual warmth that no other manufacture matches.

The grey guilloché dial, executed on a silver base, captures the light through its hand-engraved patterns with a depth impossible to achieve by machine. An 18K 6N gold bracelet with folding clasp brings material consistency from case to wrist, making the lineSport Automatique Réserve a total object of extraordinary coherence. Water-resistant to 30 metres, it offers the reassurance of practical durability without compromising an iota of horological prestige. At $77,600, this is Journe at his most boldly physical.
