Ca. Ø26.5mm, ca. 22g, 18K pink gold, super solid special 'à-goutte' case,pletely signed and numbered No.23424, Frederic Boucheron Paris, fine cylinder movement, wolf's toothing, extremely rare blue 'Louis-XV' enamel dial, signed Boucheron, original gold hands, in working order, in very good condition! Possibly due to the special dial this watch is similar to the Boucheron pendant watch auctioned in Geneva in 2004, which had a Renaissance outer case that could be used as a wall clock: (https:///go/Dlg).
