The Futur Antérieur is the third collaboration between Louis Erard and Vianney Halter, and takes a different approach from their earlier releases. Its porthole-style dial windows, gold-plated rivets on the porthole bezels and crowns, and dial and hand configurations reference Halter’s 1998 Antiqua perpetual calendar, which the article says costs more than $200,000.
The Futur Antérieur is not a perpetual calendar: one Sellita SW100 automatic movement drives its hours-and-minutes dial, and a second drives the running-seconds dial. This arrangement separates the displays while keeping the case 8.85 mm thick. The case is 38 mm in diameter, and its articulating lugs are intended to help it conform to a range of wrist sizes; the reviewer also found it wore well on a single-pass fabric or NATO strap.
The article says the brand considered a dual-time display, but Louis Erard explained that keeping two SW100 movements in harmony would be too difficult at the target price. Using the second dial for running seconds instead allows greater leeway for differences in accuracy between the movements, according to the brand.
The listed price is about $6,000 before taxes. Louis Erard is making 178 watches of each dial configuration, as well as 78 collector’s box sets containing both watches, priced at CHF 9,900 (approximately $12,075). The reviewer describes the watches as very scarce and says they were likely already gone from the primary market; this is an assessment, not a confirmed stock update.
