Here is a classic late 60's or very early 70's Zenith Autosport "C" case with in-house Zenith caliber 2552PC. The 2552 is a superior automatic movement and the pinnacle of Zenith engineering at the end of the golden age of Swiss watchmaking. Featured a stunning golden dial and onyx markers, housed in a 20 micron gold case, 33mm excluding crown, but wears larger. Oozes a real vintage vibe. Dial is perfect, no flaws. Crown unsigned. Movement has been cleaned and serviced by Shane Ede and is in excellent working order. US$375, includes paypal/ shipping (US Canada/ Europe & Japan extra shipping).
