Best purchase experience I could have imagined. Donald from Wrist Aficionado was very helpful and responsive whether by text, phone call or email. Shared videos with me and helped me get the watch I have been chasing for sometime. I have found my preferred watch dealer and will be a repeat customer. Payment processed same day and the watch ship later that day. A Very Happy Customer. Thank you everyone at the WA team!
