I have a 1992 Oyster Perpetual Datejust that I bought in 1994 new. Wore it on occasion, but was wearing it less and less as worked around areas of high voltage more and more. Finally asked a female friend if she wanted to wear for a couple of years. I guess females wearing men’s watches is becoming more popular. Took it to a place I had it cleaned (only time since I bought), they knocked two links out of the band and it fits her fine. So for now it’s “on loan” (ha ha).
I’m no watch expert but I can google stuff, and apparently the Oyster Perpetual series was introduced back in the 1940s. It is a classic Rolex design that has kept its relatively small case diameter through the decades (although it has varied somewhat). We are currently in an era of absurdly huge watches. So an Oyster Perpetual of ‘90s vintage will look appropriate — in a relative way — on a woman these days. That may be a factor in your female friend’s interest in the watch. I will add that the pendulum seems to have begun swinging back towards more normal watches sizes.
