SARTRE Eyeglasses by Gotti. Color: Dark black, Havanna, Cappuccino brown transparent, Fuchsia red transparent, Caramel brown transparent, Sea grass green, Size: 52-16, Material: Acetate, Collection: Götti Switzerland.. Elegant and unmistakably Gotti, the Sartre model takes the square acetate frame into a more refined register. It stands out for its disciplined lines, tactile quality, and all-day comfort you can rely on. Each pair begins as acetate sheet, precisely milled and polished by hand for a refined gloss. The parts are then joined using real rivets for time-tested build quality. The Sartre's restrained detailing and rich acetate palette make it remarkably versatile. Professional with tailoring, relaxed with knitwear, and always premium in feel.
