It features a grand and petite sonnerie, a minute repeater with classic gongs, and an extensive range of complications, including a perpetual calendar, dual time zones, moon phases, and an alarm. Gold-applied Breguet numerals and a hand-guilloched hobnail pattern complement the ebony black opaline dials. Housed in a white gold case adorned with 409 baguette-cut diamonds totaling 31.35 carats, it measures 49.4 mm in diameter and 16.32 mm in height. The watch is finished with a shiny black alligator leather strap and a diamond-set fold-over clasp.
