The case and movement of the watch are original and have a serial number, but the diamonds are aftermarket (they are nice quality, natural diamonds, but they are set by us, not Rolex) so the watch is considered custom and will not be covered by Rolex warranty. This watch comes with a 5 year warranty by us (we have been in business, with an actual physical location in NYC since 2004). All of the Rolex watches come with free appraisal.
