I know this is probably not the place for this so apologies but thought I would try to distinguish this one as a novice, the first thing I noticed on this was the engraved rehaut not lining up with the minute markers, being honest I dont know if this alone would make me suspicious?

looking a bit more I noticed the gaps between the end links/case (could be exagerated by the way it is being held) then after staring at it a while some things seemed wrong with the dial, I can now see the 1000, f and the gap between 300 and m looks wrong (to me)

Every time I see these fakes I am amazed how good some are, I always assumed they would be so obviously fake but even though I own a Sub and look at it everyday I still really struggle

I assume there are many even better fakes out there?
