The Matsuda - M3137 is a technical showpiece built on a tried and true round lens shape. Ribbed titanium side shields carry an elegant stained glass decor, while the temples masterfully combine hand-finished Japanese acetate with precious metal hardware. Every element reflects the intricate metalwork and ornamental precision that distinguish the collection—a marriage of structure and ornamentation expressed with subdued confidence, where heritage technique meets distinctly modern form. Handmade in Japan. Includes Matsuda box, case, and cleaning cloth.
