Update on my GWB5600 saga with Vincent Watches. Casio USA said Vincent wasn't an authorized reseller, even internationally. I didn't get the feel that the phone rep really knew what they were talking about, so they may very well be authorized in Asia, but the US call reps can't confirm.
Contacted Vincent again. They agreed to swap the watch...if I paypal'd them an additional $80 to cover postage.
Looking it up on DHL, it would cost close to that. I really don't think I should have to pay anything, but I agreed to ship it via USPS if they covered return. Cost me $17 just to stop the time suck that it was to deal with this. They received the watch and responded that they'd ship it to Casio and get back with me. That wasn't really the deal. I need to check how long I have to get this resolved with Paypal before I can't dispute.
