This one has fine Longines cal. 538 on the basis of the legendary 30CH Fly-Back.

The name Nonius results from the Portuguese mathematician P.Nunes (1492-1577) who built instruments for the measure of time. It’s a very unusual model with a special 1/10th second chronograph hand, patented in 1971 and inspired by the caliper, which allows the owner to read the 1/10th time by looking to the number of the hand “in line” with the inclined concentric minute division.
