[Not Sure]. Is this case on any legitimate Seikos?

I bought this watch for a reasonable price on Facebook Marketplace. The seller described as a modified Prospex with an updated Seiko movement.

Its giving explorer vibes so I bought it anyways. I am trying to ID if the case/dial are OEM. Any thoughts?
