Maybe I need to create a new thread but I wanted to give this one a try as it has recently been active. This thread inspired me to learn more about this reference, which in turn I have now added this reference to my "gotta collect" list. I curiously began looking at all of the typical hunting grounds to familiarize myself with condition and general asking prices and I found this piece. It is advertised as being from '69 and looks to be overall good condition but the movement made me stop and deep dive into this forum and other sources to learn more. The piece in question has a Zenith branded rotor weight stating 31 jewels
From my understanding, Movado was sold to the North American market as Unadjusted and fewer (17) jewels for import reasons. The rotor weight should reflect this by the Movado branding and stated 17 jewels. After my deep dive, I came to the conclusion that this rotor weight was likely replaced with a Zenith one during service. The watch is currently located in Belgium and is sold by a dealer. When I asked abut the rotor weight, they claimed the movement was entirely original to the watch. With skepticism, considering they likely are not the original owner/purchaser of the piece from ~69, I come here wondering: is the Zenith branded rotor weight more likely a part replaced during service
or is there any documentation showing early references possibly came 31 jewel Zenith movements? Here is the watch in question
