Euclid
The interplay between titanium and acetate in the Akoni // Euclid inspired by the ESA’s Euclid Telescope, embodies intellectual precision and cosmic exploration. A refined homage to the classic Clubmaster silhouette, it blends vintage elegance with modern engineering, featuring a linear flat-top brow-line, pressed titanium detailing, and an open-drilled bridge. Sculpted temples with aerodynamic faceting, knurling, and acetate tips enhance both comfort and technical sophistication. Euclid is eyewear that balances timeless style with visionary clarity, for those who navigate the world with purpose and distinction. Handmade in Japan. Includes Akoni box, case, cleaning cloth, and 1-year manufacturer warranty.
