The Basics

Only flying is better than this! This thought will certainly cross some peoples‘ minds when they are racing down a dusty mountain trail into the depths of the valley with the Terranaut I Trail on their wrist. At Nautische Instrumente Mühle-Glashütte, they only have one response to such a thought: You should give everything a try at least once. Their chronograph would certainly also feel right at home when taken hang-gliding or gliding. After all, this watch is exactly in its element both on the land and in the air. As a pilots‘ watch with its feet on the ground, the Terranaut I Trail will impress wearers with its generously sized case with a diameter of 44 millimetres, their precise MU 9413 chronograph mechanism and its instrument design that makes no compromises. Reference M1-40-53-NB has a black dial and is fitted a black synthetic strap
