We found this one in an old military airfield but it was used also to cars. A friend to me sat for many hours – he is a pro in old watches – The “Omega” key was gone so somebody had used a tool to wind it up. I could have chromed that part but didn´t.
This is perfect to put in your airplane or in your staff car.
