This watch is built with the world renowned automatic Valjoux 7750 chronograph movement and was made by the German company Erich Lacher (Laco) in the early 2000's. It is a model 860890 and is a large, Pilot style watch with display back and I wore it only a few times. I have noticed that some of them have the company logo on the dial and some don't. This one does not. I honestly don't know if that makes it more or less valuable but personally I like the cleaner look of it without the logo. The 860890 is a discontinued model that is hard to find. Made in Germany by Laco, the original maker of the legendary "Beobachtungsuhr" aviator's watches. Here are some specs: 42mm diameter bead blasted case, ref. 860890 Valjoux 7750 25 jewel movement Screw down crown Luminous black dial Quick set date Original Box no papers It works well and keeps accurate time. Watch shows little use and runs fine with the chronograph hands resetting back to their zero positions as they should. This is a desirable model, long out of production.
