I purchased 2 watches previously from Andrew, great watches. Being so happy with the Rolex Prohunter GMT I purchased, I ordered another, same stock no., same price. The watch that I received was totally different from the 1st Prohunter GMT I ordered. The first had an ETA2836, AR coating, the new watch has a low beat movement, no AR. I have emailed Andrew several times about the mistake and he keeps insisting he has been in business 16 years and makes no mistakes, how do you deal with someone like that? Will probably never buy another watch from Trusty Time/Andrew. Since Andrew will probably not handle this matter equitably, I will get my revenge by posting on as many site as possible, my only recourse.
