Designed by Marco Galleani and handmade in Sabae, Japan, this exclusive gold edition of OH-01 is a technically challenging model made from Japanese titanium. The 18 karat white gold lenses with extra coating increase the impact resistance and protects the gold. The design combines classic features with a contemporary appeal achieved by the a special clip that aligns the titanium to the round acetate form. The smooth lines are the result of rigorous attention to detail by the skilled craftsmen of Sabae. One pair takes up to six months to complete.
