Yesterday, YEMA announced its first ever Navygraf chronograph with a pair of Valjoux-powered timepieces: the Navygraf Chrono and the Navygraf Chrono UTC. The iconic Navygraf design has been a staple in the brand's catalogue since the 1970s; however, it has always remained a three-hander throughout its various iterations. Now, you can have it in a tri-compax, lever-action chronograph.
