At 49.4 mm in diameter and 16.32 mm in height, the white gold reversible case of reference 6300-403G-001 carries a total of 118 baguette-cut emeralds weighing 7.87 carats alongside 291 baguette-cut diamonds totaling 20.54 carats. The bezel on the time side is set with 96 baguette-cut emeralds (6.99 cts), while the calendar-side bezel and case receive 291 baguette-cut diamonds (20.54 cts). The case is humidity- and dust-protected, though not water-resistant.
Both dials are rendered in ebony black opaline on an 18K solid gold dial plate. The time side features gold applied Breguet numerals over a hand-guilloché hobnail pattern, while the calendar side presents a clean ebony black opaline surface. The manually wound movement delivers an exceptional array of functions: grande and petite sonnerie, minute repeater with classic gongs, alarm with time strike and on/off indication, date repeater, strikework mode display, strikework isolator indication, movement and strikework power-reserve indication, and crown position indication.
The perpetual calendar is instantaneous, displaying day, date on both dials, month, and leap-year cycle by hands, with a four-digit year shown in an aperture and moon phases indicated alongside a 24-hour and minutes subdial. A second time zone with day/night indication rounds out the complications. The watch is worn on a shiny black alligator leather strap with square scales, hand-stitched, and secured by a fold-over clasp set with 22 baguette-cut emeralds totaling 0.88 ct.
