Sartory Billard's SB04 timepieces are known for their highly individualized specifications, and this Horophile Final Edition—featuring the brand's first in-house guilloché dial—is no exception. The dial features a 120-cut sunray pattern that shifts with intense iridescent flares ranging from purples to oranges. This results in one of the most mesmerizingly dramatic dial executions we have ever encountered. The way the edge of the boxed crystal captures and distorts the dial's colors on another plane further enhances the spectacle. This vibrant display is framed by a 40mm sandblasted steel case finished in a stealthy matte black DLC coating. The watch comes fitted on its bespoke purple Delugs leather strap, custom-made in collaboration with Sartory Billard to complement this limited edition. Flipping the watch over reveals a sapphire exhibition window showcasing the reliable La Joux-Perret G100 movement, complete with a matching purple fluted rotor ring and a robust 68-hour power reserve. Limited to just 20 pieces worldwide, this rare edition has secured its place as a highly coveted collector's piece, marking the grand finale of a celebrated series. At this price point, very few watches can match the SB04's level of distinction and ability to command admiration while remaining exceptionally wearable and ergonomic, and this would be a standout addition to any collection. •Guaranteed to be 100% authentic. •Comes with the SB boxes and papers (dated in 2025) as shown. •Rapidly sold-out limited edition of 20 pieces. •All functions are operating as intended.
