BEWARE! I never review on line as myself, don't read the on line reviews. My friend bought me a UBOAT watch worth over $2200. 00 on AMAZON using DEXCLUSIVE as a third party seller. Tried to contact DEXCLUSIVE through AMAZOn and they wanted to not deal with it. Tried the A-Z guarantee on AMAZON without any luck. Please, before spending your money go to an authorized dealer. DEXCLUSIVE are fraudulent. I would rather buy the knock off's from the Chinese sites. I will now take my watch to a watchmaker to verify and go after DEXCLUSIVE. Stay away from this company and AMAZON. Both have no professionalism in dealing with a legitimate issue.
