I own several Roo's ,all mine are saphire,i ared the crystals of all watches,the ar i use is almost colourless ,when applicated on mineral it comes out with a blue hue!
Got an Panda,Chronopassion,Rubberclad,Rubberclad RG,all built this year,en they turned out colourless.
But something is going on at the moment in china!
My friend ,who does the AR ,sended 60 chrytals from different watches ,also Aproos and some diver chrystals to the AR factory,he showed me the result,keep in mind he is using the same vendor (7layer AR)for 6years now,the application on almost every chrystal was different,some colourless, some purple ,some blue,some rainbow,some of the crystals didnt even take the AR evenly!
He will have an appointment with the vendor this week to search for the reasons!
I am very curious about the results
