====== Triovis ====== **Triovis** is a [[precision adjustment]]. This patented precision adjustment system comes from the [[Valdar]] SA, which belongs to the [[Swatch Group]]. The Triovis precision adjustment is, inter alia, used by [[Nomos]] and [[Richard Mille]]. A micro-threaded screw reaches into the fine outer toothing of the regulator disc so that it is possible to adjust it precisely. {{tag>Terms}}
