Rolex Oysterquartz Guide: Datejust 17000, Day-Date 19018, Calibers 5035 and 5055 | Ultimate Watch

The Rolex Oysterquartz is the watch most collectors walk past and most dealers underrate, which is exactly why we keep buying them. Launched in 1977 after five years of in-house development, it was Rolex's answer to the quartz crisis on its own terms: a proprietary, thermo-compensated quartz movement housed in a waterproof Oyster case with a flat-sided, angular profile and an integrated bracelet that looks nothing else in the catalog. Two families ran side by side. The Datejust Oysterquartz in steel and steel-and-gold, and the Day-Date Oysterquartz in solid 18k. Rolex built roughly 25,000 across the entire run before quietly discontinuing the line around 2001 to 2003, which makes it one of the rarest modern Rolex families you will ever handle. We are on 47th Street, we see the mainstream Datejusts and Submariners every single day, and the Oysterquartz is the one that still makes a collector stop at the counter. It ticks instead of sweeps, it wears like a 1970s design brief made real, and it has become the quiet insider's Rolex.
