The Classic Fusion Aeromoon by Hublot with its sapphire dial is a resolutely contemporary skeleton watch equipped with a complete calendar that took two years to develop and features a pointer-type simple calendar, days and months appearing on skeletonized disks appearing through two large apertures, as well as moon phases. The latter are displayed in an original way through a broad 13mm-diameter window by means of two moon-colored planets rotating beneath a partially frosted sapphire crystal. Everything has been done to accentuate the depth effect on this model as a whole. Pre-selected in the Calendar watch category of the Grand Prix d’Horlogerie de Genève 2015, the Classic Fusion Aeromoon comes in two versions : one in King Gold (Hublot red gold with 5% platinum) version, and the other as pictured here with a titanium case and a distinctive matching bezel, punctuated by six H-shaped screws and black composite resin bezel lugs. The calendar correctors are integrated into the case middle at 2, 4, 8 and 10 o’clock.
