The number on the reverse is: 20 0520 355
I was able to use this to determine that the movement is a Zenith 1740 and the watch originated from some time between 1972 and 1978.
I’d appreciate a price check on this, as I’ve found a massive price range on Movado Zenith Museum watches, ranging from $100 to $1000.
Looks like you’ve already done more research on this than anyone here probably will. It’s not necessarily an enthusiast brand
Hmm, okay. Do you have any suggestions on how I could narrow down its value? The range I’ve seen is just too big.
Narrow it down? Well the expensive ones are solid gold. Yours is tarnished. Gold doesn’t tarnish so I would guess yours is on the lower side of the scale
I assume that’s the base metal showing through, as it’s only gold electroplated, which wears off super easily.
