Don't know much about this, but I will do my best to describe. Case: 40mm coin edge nickel chromium in good shape with some wear as pictured, most on case back. Dial: Original branded P. Fois telemetre dial Breguet numerals with nice patina, in great shape. The hands are blued steel Breguet style. Movement: I believe this is a Landeron-Hahn caliber 25 monopusher in nice condition. Runs well and keeps good time. Chrono runs and resets to zero, but stops after a few minutes. Once you stop and reset, it starts up again. Service history unknown. Crystal and Crown: crystal is domed acrylic in great shape. Crown is plated, showing brass as shown. Overall a really neat 1930s chrono with a great look.
