Junghans Watch Telemeter 27/3880.46. The telemeter and tachymeter display were first combined in a single Junghans chronograph in 1951. This legacy is now being perpetuated with the Telemeter, a new retro release of the classic chronograph. An extremely beautiful watch, the Telemeter is as elegant as it is technical and sporty, and just as relevant today as it was upon its original release nearly 70 years ago.
