Ravaro - Onyx Black
By
NAVANOS
Description
Ravaro Diver - Onyx Black
Some instruments don't announce themselves.
The Onyx Black is the most commanding expression of the Ravaro. A professional dive instrument where every element recedes into darkness except what matters most. The dial. The hands. The lume. Forged from 904L stainless steel, COSC-certified, and independently verified to true ISO 6425 standards by TIMELAB Geneva. Advanced antimagnetic architecture developed in collaboration with Systron EMV in Switzerland.
Rated to 300 meters. Factory-tested to 400.
Built for those who let the instrument speak, not the colour.
