I've been looking for a Pro Gmt and a seller contacted me that he had one for sale. I asked if it kept + / - time per 24 hours. He said he hadn't worn it but would. He contacted me with the results, and the deal was consumated via paypal. He e-mailed last night that he was refunding my money as he realized how nice the watch was and wanted to keep it. He refunded my money.
So somewhere out there is a new Doxa-holic.
I'm still looking for the Pro GMT, so if anyone has one that they would like to get rid of please contact me, BUT DO NOT WEAR IT!! lol
