I think it is a 105.012 pre 66 because of the beveled case back, and the short pushers. However I cannot open it up easily, and so I am sending it straight to STS. The pushers do not work, the chrono subdials dont reset – its in a terrible state and it is filthy!

Short pushers and double step back.

Although the back is damaged, I do not think they succeded in opening it – I did not! I know when to send to people better than me.

Now its gone to STS. More will be revealed!

Edit: the return is written about here
