Help Needed to identify watch

[Jimbold]

Hi

Can anyone help? I'm trying to identify this watch. I've found plenty that look similar, but they all have the name 'Omega' on the face. This one doesn't. There is nothing written on the case and I haven't opened the back (yet).
Many thanks in advance.

Redialed watch, remove the caseback to find out what it was before someone whitewashed it

Still an Omega
