Gerald Genta "Success" Perpetual Calendar Moonphase 18kt Yellow Gold "Marble dial" Ref G2994.7This is an exceptional Gerald Genta 'Success' Perpetual Calendar Moonphase in 18kt yellow gold. Featuring a distinctive rounded octagon (may we call this pebble shaped?) case, a nod to Genta's love of this form, this watch is a perfect blend of luxury and understated elegance. The star of the show is the incredible marble hardstone dial, notable for its remarkable thickness, and especially elevated by the faceted glass, which sets this watch apart.
