A miracle of transparency, the Reference 5304 self-winding Grand Complication with minute repeater and retrograde perpetual calendar is reinterpreted in a new rose gold version on which the bezel, lugs and fold-over clasp are enhanced with 80 baguette-cut diamonds (~6.22 cts). This sparkling touch highlights the ingenious calendar display system with sapphire disks. The "leaf" motif engraved on the white gold inserts adorning the sides of the case is echoed on the off-centre rose gold mini-rotor visible through the transparent case back.
