BARTON PERREIRA Fossett aviator-style acetate and gold-tone titanium sunglasses

"One touch, and you instantly get it," says co-founder Bill Barton of the beauty of Barton Perreira's frames – each pair is meticulously handcrafted in Japan in a process that takes weeks to complete. These bold aviator-style 'Fossett' sunglasses are made from hand-bevelled acetate with gold-tone titanium inserts at the bridge and arms.
