This showed up on my local Facebook page. Been talking with the seller.
Not sure if this is a Franken-watch, or variation that I just can't find.
Case is marked 16610 with a serial number of R919973 (1988). I was told that the bezel insert font suggests it's from a 16613. Gold letters and hour markers would usually be accompanied by gold bezel, crown, and band center links - at least that's what I mostly see.
I can buy it for $1000. Thoughts? It's a little grungy, but seems to run just fine.
