This purdy is a Zenith 46.0. A 7 jewel movement based on the ESA 9361. A really high quality quartz movement in the late 1970s and thanks to the Ebauches architecture easy to service. The pics are from a donor watch I scored off eBay and was happy to see that dial, hands and movements are really minty. I have another example ticking away in a 1979 Defy which hasn't lost or gained a single second since re-setting it on Nov. 22nd 2019. So, if you think vintage Quartz are inaccurate and terrible to service, think again 📷






Beautiful movement. Brilliantly photographed.
great post and images man! very insightful information for those sleeping on some breathtaking vintage Quartz pieces.
