Any ideas on reference for this vintage Seamaster

I'm not really a vintage Omega guy (so far!) but did spot this rough Seamaster going into an auction at a very basic auction house soon. Looks to be mingled in with a load of estate clearance bits. There is only one photo and it isn't great, no shot of the back. I have been trying to figure out what it is and when it is from (late 50's/early 60's presumably).

It appears to be a strange one. The bracelet presumably isn't an original one (looks like the gold plating is worn/peeling in places).

The bezel looks to be gold but the case looks to be steel.

Difficult to tell the colour of the face

The nearest I have found is this one which seems to have the same sort of crown, similar lugs and stylised S in Seamaster:

Any thoughts?

My uneducated guess is that it's the fake reference 🙁

Yep, I was really conflicted about it. Thanks. I did think it was odd that so many little details were there on it. The bracelet is horrible!
