Just visited their website, and it looks like it's either been hacked, or... what? http://www.globaltempus.com/
No. I'm saying I have no idea who they are. I've not seen them mentioned on this forum before - given that no one else has responded, I'd guess I'm not alone in that. Some shady grey market thing? A bricks and mortar with a website? Seriously, who are/were they?
Oh gotcha! Yeah, oddly enough I placed an order for a watch through Chrono24, and the seller was... these guys! I ended up cancelling the order before the watch shipped because the seller was behaving very strangely. What a relief that I didn't order what would have turned out to be a stolen watch!
