Help needed: Seamaster 30 - redial or fake?

Can someone please chime in, is this fake/redial.
It's supposed to be Cal. 613.

Thought so. Thanks for confirming because it was cheap but the dial didn't look right. However I read the topic about special dials and was still thinking it could be one of them.
Strangely enough the seller had 100% feedback.

Is the back fake too? Btw I think it had like 10 bidders at least.

I couldn't find any similar watch anywhere, so that was alarming. The one with a black dial and Seamaster 30 seem to use cal. 286. Too sketchy so I asked here.

Of course when I first saw it was I was tempted before checking and googling - after all the dial looked grayish, and not deep black like most redials. I couldn't tell from the back either. I mean who doesn't want a cheap black dial manual?

If it wasn't for this forum and all the help I got here on previous redials, I probably would have bought it.😁

Missing its case clamps also so nothing is holding in that movement apart from the crown

The back looks genuine it's just Been painted over and them wiped clean so the paint is in the engraved part
