The Vintage Wrist Watch Company has dated this piece to the 1920s.
Gents 1920s/30s Landeron-Hahn pilots chronograph watch.
The watch has a high end column wheel Landeron-Hahn movement which is working nicely.
In the 1930s, Charles Hahn and Marcel Dèpraz co-developed a novel new technique that used simple stamped plates to start, stop, and reset the hands of a chronograph movement. Their cam-switching technique would revolutionize the chronograph market, dramatically dropping the price of the technology and leading to a wave of new movements.

This particular watch measures 38mm diameter excluding the winding crown, buttons and lugs. The case is a combination of stainless steel with a nickel plated centre. The case is in good condition, a little light marking but nothing serious.

The later lens is in good condition.
The dial is in its original finish, there is a brand name but difficult to read as it is quite worn. Blued steel hands, a constant seconds sub dial and a 45 minute register, telemetre and snail trail spiral. There is some age related wear and darkening to the dial.
A later leather strap has been fitted.
The watch comes in a new presentation box.
