If this watch isn’t full of history, I don’t know what is. Longines launched this watch in 1972 to celebrate their achievement in becoming the official Olympic co-timekeepers (along with Junghans) -taking the spot from their direct competitors, Omega-.
The blue dial is simply amazing. The white lettering really contrasts with the colors chosen by Longines and the chronograph hand (which usually is more orange-ish colored) has turned into a deeper yellow that really meshes together the whole set of colors.
Wether you like chronographs or stopwatches, this watch does it all. Pop it on the wrist and you have an amazing monopusher movement. Take it off and put it in your hand and it’s ready to operate as a stopwatch!
