Ever wondered how glasses are made? Leading London optical outfitters Cubitts is a modern spectacle maker that places bespoke at the heart of its offering. Cubitts’ inimitable specs fuse together design and functionality and we’re inviting you to go behind their doors to see just how their 18 karat gold frames are made. With each frame built to be worn for life, their philosophy is always to repair when possible – rather than replace. The techniques you’re about to see combine cutting-edge technology with traditional craft. These made-to-order 18 karat rolled gold frames (exclusive to the Jermyn Street atelier) are handmade in England’s oldest surviving spectacle factory.
