(I asked on the general forum and people had no idea. But they had plenty of opinions of whether this was a good idea or not. But I wasn't really asking for an opinion from the "good taste police" and people advising on used watch valuations which I wasn't asking about either.)

The TrueDome D29 aand D21 will both fit Datejust 36mm 4 digit references. If its a modern Rolex with sapphire im not sure which reference number that crystal is but acrylic will not safely retrofit.
