Thanks! I know I saw it in store once late last summer and it was gone by my next visit. They also had a tag aquaracer a few months earlier, I remember looking that up and it was essentially USD pricing but in CAD, as if the dollar was at par. Looks to be the same case here. Costco has really upped their watch game!
There's no question it's authentic and not stolen, looks to be a display model or return, blank/unstamped papers, unsized band with plastic still attached, no hairlines on the clasp and the rubber strap has that pleasant vanilla scent characteristic of Bonetto Cinturini straps (I'd be shocked if they aren't the OEM band supplier for Oris)
