• Only Watch 2017

ArpalOne, a unique watch signed by
Laurent Ferrier and URWERK
For Only Watch 2017

It’s neither a Laurent Ferrier watch nor an URWERK, yet the signatures of both firms appear on its back. The existence of this unexpected watch defies logic because it is the joint effort of two watchmaking companies that couldn’t be more different. Each bases its identity on the opposite ends of watchmaking’s stylistic spectrum. On one side, the expression of time-honoured traditions; on the other, an anarchic effort to overturn conventions. Laurent Ferrier and URWERK have created a piece of work that is unique, for only one-of-a-kind watches qualify to be sold at the Only Watch auction in aid of the battle against Duchenne muscular dystrophy.

“We undertook this project with the greatest respect for each other’s work; We held a great number of operational meetings, setting up a dialogue and developing a friendship that is apparent in the final result. We were aiming for subtlety rather than performance.”
