The W watch

Introducing a one-of-a-kind dive chronograph | June 2007

The design and concept of the W watchwas born in the mind of Christophe Golay, a creator of innovative time-keepers, whowas inspired by William’s underwater breath-hold exploits. Hence, the W was not meant to be a dive computer, but rather a time-piece for underwater adventure-seekers such as William.

Its concept resides in a removable safety cage set above the glass, allowing water to pass in-between, creating a magnifying effect underwater. The glass is also protected by this cage which will take the blow of real-life encouters in and out of the water.
