Z-Parts TITAN Z-120

II bridge model that enhances the presence of metal by combining crisp press parts and 1.4mm thick rim. The lens size is slightly smaller at 52mm, and the lens curve is set to 4.0, making it possible to use it with either sunglasses or glasses. The all-metal temples are press-processed to provide springiness and fit, and the hinges, including the endpieces, are machined using a single-piece Sparta process to create a design with a sense of unity. The lens shape is arranged automatically. Surface treatment uses highly durable gold direct plating and ion plating. Titanium natural without surface treatment is also available.
