A few details about this watch. The coolest element of this watch is the mechanism, ie the famous, not produced, Lemania 5100 designed especially for pilots of military aircraft and used in many military watches. Hence the features, such as the additional 24-hour indicator on the subdial and a very interesting chronograph system, with centrally located second and minute hands of the chronograph. This gives an amazing effect and is very readable, if you measure time in one-hour intervals. And it looks amazing. This mechanism with such histor, as well as the case and bracelet made of titanium gives an amazing effect and creates a beautiful toolwatch. It is also lighter and more resistant than steel watches. I highly recommend it, especially for active users or those who often use the chronograph. You will be thrilled. I sell as usual, because I am saving for a new target.
