Do Not “UPGRADE” your Rolex CRYSTAL‼️ In this video, @watchguys_ steps up to buy a used Rolex Datejust. The customer wanted a “scratch proof” crystal, so thought that upgrading to a sapphire crystal would help with this. Unfortunately, this left the watch failing water pressure tests. Also, the diamonds added to the watch were aftermarket, meaning the Rolex bezel would need to be replaced — this means a lower price for our customer. Comment below if you thought “UPGRADING” your Rolex would result in a higher resale value! Follow @watchguys_ for more and shop Rolex watches on WatchGuys.com.
