Could anyone identify this Rolex Crystal for me please?

[benr1994]

Hey there I know it might be a long shot but I have searched for hours online to find it but have not been able to.

Sorry if this is in the wrong place to ask.

It measures 28 mm in diameter and around 3.5mm in height. The material is plastic/plexiglass.

I am not somebody with knowledge of watches let alone Rolex but I spotted a box of old watch parts at an auction and of course the Rolex name stood out and there were 5 of these crystals all the same. It seems some have decent worth but it is very hard to figure out which model they are for.

Any help would be appreciated thankyou.
