Named after the peerless astronomer, Alexis Clairaut, this frame has a two-tone “frame within a frame” design that is skillfully engineered utilizing 10 hidden screws to secure the innovative construction. An angular double-bridge compliments the round and flat 2-base lenses to create a futuristic interpretation of a classic silhouette. The frame is crafted out of pure gold-plated titanium and adorned with intricate laser etchings and tastefully hand-enameled details. The frame's distinct look can only be achieved through sculpting solid blocks of titanium. 100% pure titanium plated in 18k gold combined with matching titanium temples and a hidden spring hinge. Individually numbered and handmade in Japan from the world’s finest artisanal craftsmen.
