About the Freak family

The Freak, introduced in 2001, changed the idea of what a watch could look like. It has no dial, no hands and, in its original form, no crown: the movement itself rotates to show the time, and it was among the first watches to use silicon parts in the escapement. Later generations include the Freak X with a conventional crown and the Freak One.

The references in this catalog use the UN-230 and UN-240 calibers, in materials such as Carbonium, titanium and gold. These are complex watches, so test the time-setting and winding, and expect buyers to ask for a service history from Ulysse Nardin.
