Martel Cal 1111

VERY interesting transitional piece. As clear it is that Martel made the chronograph and otherwise complicated movements for UG, I'm not sure that Martel made any three hand movments for them, so that makes this the Ur-movement for a whole generation of Zenith automatics. Further, it looks as if Martel may have carried on the case numbers from their UG pieces, although the references were changed (or maybe just started with 1000000, but no way they had sold that many watches by the time this was marketed.

NIce historical piece, and nice piece regardless.
