If I can only find me a Tag Monaco Classic now...

Update: took it to a fantastic guy in Arlington, VA on my travels (Lee at 24 Hr Watch Repair on Wilson, if anyone is ever nearabouts).  I tried three other repairmen first who either refused or said they couldn't open it.  Lee whipped it open, found the prodigal screw, gave it a one-over for any cleaning and fine tuning, and then measured the movement--he said it's one of the best replicas he's seen, said the movement was Swiss grade.  

Sealed and running fine now, thanks all for your input.  

Knocking hasn't produced a screw that I can see, but I'd prefer to have a pro or semi-pro open it and give it a look-around for anything more invasive of course.  I'm very much a novice and love the watch and don't want it damaged.  I showed it to a watch repairman at a jeweler nearby; he refused to open it and said most repairmen would as well.  He said the screw could have gotten caught in a gear...he also tried to convince me even replicas are all under warranty, but that didn't make sense to me...but bottom line, he said send it back, don't try to open it. 

Yes, it appears so.  Good catch.  What do you recommend? 

(If a better angle helps, please LMK)

(And I do apologize that these are not full-pro grade, but I'm traveling and doing the best with what I have right now)

Hey folks, same problem and very frustrated.  None of these tips are helping.  

Got it yesterday, it worked and kept perfect time, then wound down.  I've wound it back (until resistance, don't believe I overwound) and can't get it do anything now.  

This is a 1:1 N00b.  Am I overlooking any tricks?

Thanks, help appreciated!
