Datejust 16233 1998 with acrylic glass

[scallywag1944]

I may have received some misinformation on my watch. My father-in-law has several DJs and may have confused or merged the info he was giving me. It was only ever serviced at Rolex and I have the receipt from the last service where they replaced the crystal. My DJ is from 1978 so it would have had acrylic crystal all along. I haven't removed the bracelet yet to see the ref number but I'm assuming it will be 16010. It is now my understanding that Rolex didn't start putting sapphire crystals on the DJ until the late 80's.
