Scarecrow Boat
··Burt Macklin, FBIGood eye - I think you are on to something. I was looking at the case back etching, and after doing the below experiment, it is much more consistently-aligned with the notches on both watches than I originally thought. (Edit, or should I say "in both sets of pictures?")
I guess we know what my "pretty confident" is worth now
There is also the scratch above "...R-120" that I'm not seeing clearly on keeponticking's watch, but that could be the lighting. Maybe @keepsonticking can share their thoughts since they have the watch in-hand.
The more I look at it, I feel pretty confident that it is the same watch. Going to the original watch from 2016 from @Fordex, which here is a link to it

There is an image that shows the backside of the lug
Now, @keepsonticking ebays listing image
We can see the same scratch on the back side of the lug. Coincidentally, the surface the watch is photographed on appears to also have the same texture pattern… to show what I mean, here is an image from @Fordex
And image from keepsonticking
