The stainless steel bracelet from the AD is $800 list price so it would definitely be worth repping. Supposedly there are multiple size rubber straps, but if the gen copy is from an Asian AD, then it may have the smaller size as most Asians typically have smaller wrists.
I'm not sure about the Costeau's hour markers, but on my regular aquatimer, they seem to be much more reflective (almost shiny). I will try to take some photos tonight to see if I can get a comparison.
BTW, I shoot using my wife's camera (Can 5D), but don't know how to use any setting except auto....so if anyone can send me some PMs on how to take clear pictures I would appreciate it. I can't control the AF points so they always focus in on a single area leaving the rest blurry.
