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.
A watchmaker did a full service and took some photos during the work. This is perfect to put in your airplane or in your staff car. The work cos me 450 USD and it is a perfect movement.
