I love the 16760. I’ve been stashing away cash for a while and might be ready to jump on one this year. My question is when did the text change from “oyster perpetual” to “oyster perpetual date”. I was born in 1984 and I kind of want one from that year but it seems some from 1984 have the no date face and some have do not. Is there any definitive information when the change happened? It’s not make or break. I think for personal reasons I want a 1984 serial number. More curiosity than anything.
