F.P. Journe Astronomic Souveraine Ref. AST Classique Stainless Steel Grey Dial (2026)

The Astronomic Souveraine is the most complicated wristwatch F.P. Journe has made: eighteen functions across two faces, including a minute repeater, a tourbillon, sidereal time, an annual calendar, equation of time, moon phase and sunrise and sunset. It descends from an astronomical pocket watch Journe built for a collector in 1987, and reached the collection after the Astronomic Blue prototype was sold for charity at Only Watch in 2019. Output runs to a handful of pieces a year.

The case is steel, 44 mm across and under 14 mm thick, which is the point: Journe chose steel for the way it carries the sound of the repeater, and kept a grand complication to the height of an ordinary dress watch. The dial pairs a white gold plate with whitened guilloché silver, and every indication is set by the crown alone. Part of the Classique collection at F.P. Journe.
