I would have thought the price is the giveaway. All fake, ebay is a bugger for that. 

That is excellent news I hope the video I posted helped you in understanding how the chime and strike work. 

I keep cruising through Ebay and these have popped up. The high end watches have to be copies, surely? On the Navitimer - no date window. On the Submariner - lume dots coming out of the hour markers. The Oyster Perpetual - I can't find an example that has Roman numerals, no date window, no second hand and the way the bracelet attaches to the case. Looks like the case has no lugs?

I have one of those too. I think it's for mounting polishing and grinding wheels.
