Beda'a Angles Guichets Watch
The guichet watch, named for the French word for window, tells time through apertures cut into the dial rather than traditional hands. Cartier's Tank à Guichets made the format famous in 1928, and Beda'a revives it with the Angles Guichets, a stainless steel 37mm octagonal watch built around two stacked windows. Through the upper aperture, Sun and Moon icons travel slowly across the opening on a 24-hour cycle, marking the passage of day and night. Below, a flush-set arrow tracks a rotating minute disc in five-minute increments. To make it work, the hand-wound Peseux/ETA 7001 calibre was modified to run at half its usual speed, completing one full rotation every 24 hours.
