The Matsuda - M3156 combines thoughtful design with premium craftsmanship. The round frame features an arched titanium bridge and rim paired with hand-sculpted Japanese acetate temples, while an aviator-style top bar adds a bold architectural element. The signature M+N engraving along the rim provides a subtle mark of distinction—structure and ornament in the considered balance Matsuda has refined for decades. Handmade in Japan. Includes Matsuda box, case, and cleaning cloth.
