Is this a 'Ranchero' or a 'Seachero'

Hi folks,

I came across this watch on sale which is stated as Ranchero 2990-1.
I did some research on the 2990-1 and came to realize that maybe the dial on this watch could be a Seachero 2937-3 instead?
So how about the case? Could it be a 2990-1 case with a swapped dial? Or could it be truly a rare Ranchero 2990-1 just as how the seller explains in their website.

Along side, the case of the watch is engraved as 2990-1. I find it interesting and would like to have some advises from the experts in this forum.

Thank you.

The lume markers look very suspect to me and matches the hands exactly. In addition, I haven't seen the Ranchero hands with this dial. I suspect this was thrown together with a repainted dial.

I think it has been relumed.
