At first glance, you might be confused as to how to tell time on the Ora Unica, but it's actually quite simple. Just look at the position of the inner end of the squiggle for the current hour, and the outer end for minutes. Simple, elegant, and truly unique. 36mm stainless steel case, leather bracelet and water resistant to 3ATM/30m. The Ora Unica, designed by Denis Guidone for the Milanese Nava Design of Italy, is an accessory that takes fun of the time, for design lovers that make the imagination and the irony their distinguishing feature.
