Bought this big fellow yesterday. He is a Cal 7806 with a Valjoux 7740 which sort of looks like a Heuer MicroRotor with all of the auto stripped out. The watch was very dirty when I got it and it has been given a bath both literally and in Photoshop for its portrait.
Great looker, I love these classics and hope to acquire one some day when the right circumstance comes along.
That's very nice John. There is definitely one of those on my wish list, perhaps with a Cosmonaute to keep it company.
