In my opinion they are not very different, for me there is not much difference on acrylic glass. I found the Clarks to be excellent as an alternative to the original for the sapphire on my Datejust.thank you very much for the input! i ordered it alongside with a super dome for my 5513. Lets see how they compare to clarks.
Would you say the quality is on pair?
Among other things, the glass I told you fits well on the Raffles case and when pressing the bezel ring it didn't give me any breakage problems, something that reading on the forum in some cases Clarck acrylic had caused. I hope it meets your expectations as it did for me
