  5. The result, two years of r & d on, is a launch collection of six styles, each made from japanese steel, each with patent - pending and each dispensing with anything extraneous to focus on assorted new mechanisms : a flat bar with sections that open out to keep it in place once passed through the button - holes ; an s - bend that swivels to lock into a square shape ; and, most radically, a cufflink with a twist mechanism that, rather than pull the two ends of a shirt - cuff together, creates a space between them, making room for an outsized watch

    經過兩年的研發，該公司的成果是發布了一個由6種款式組成的系列，每種款式都由日本鋼鐵製造，每種都將申請專利，每種都省去了無關的設計、將重點放在各式各樣的新裝置上：一塊扁鋼條，上面附有向外張開的部件，使袖扣穿過紐扣孔后就能固定住；能夠旋轉的s型彎曲，可以固定進一個正方形的外形中；更為激進的是，一款具有扭曲設計的袖扣不是將襯衫兩端連接在一起，而是在它們之間創造出一定空間，為一隻特大號手錶留出了地方。
