The Rolex That Rolex Wants You to Forget
Between 1977 and 2001, Rolex produced a quartz watch. Not just any quartz watch — a thermocompensated quartz Datejust and Day-Date with an integrated bracelet design that predated the Royal Oak Offshore by 16 years. The Oysterquartz (Refs. 17000/17013/17014 for Datejust; 19018/19019 for Day-Date) was Rolex’s response to the quartz crisis — and it’s the most interesting footnote in the brand’s history.
Why Rolex Made a Quartz Watch
By 1975, Seiko’s quartz movements were decimating Swiss mechanical watch sales. Rolex, despite being the world’s most prestigious brand, faced existential pressure to offer a quartz alternative. Their response was characteristic: if Rolex was going to make a quartz watch, it would be the best quartz watch ever made.
The Caliber 5035 (Datejust) and 5055 (Day-Date) were thermocompensated quartz movements — meaning they contained a temperature sensor that adjusted the quartz crystal’s oscillation frequency to compensate for temperature changes. Standard quartz is accurate to ±15 seconds/month; thermocompensated quartz achieves ±5 seconds/year. The Oysterquartz was 1000x more accurate than any mechanical Rolex.
The Integrated Bracelet
The Oysterquartz’s most distinctive visual feature was its angular, integrated bracelet — flat links with sharp geometric transitions from case to bracelet. This design was created by Gérald Genta (yes, the same Genta who designed the Royal Oak) and predated the AP Royal Oak Offshore’s aggressive aesthetic by over a decade. The bracelet gave the Oysterquartz a distinctly 1970s-futuristic appearance that was radical for Rolex.

Why Rolex Killed It
By the late 1990s, the mechanical watch renaissance was in full swing. Buyers who spent $3,000+ on a Rolex wanted a mechanical movement — the prestige of a “real” watch. The Oysterquartz, despite its superior accuracy, was seen as contradicting Rolex’s core identity: mechanical excellence. Rolex quietly discontinued it in 2001 and has never acknowledged quartz since.
Why Collectors Want It Now
- Rarity: Only ~35,000 total were produced over 24 years — compared to millions of mechanical Datejusts. The Oysterquartz is genuinely rare.
- Genta design: The integrated bracelet by Gérald Genta makes it a design artifact. It’s a Genta-designed Rolex — a combination that exists nowhere else.
- Contrarian appeal: Wearing a quartz Rolex in a room full of Submariners is the ultimate flex for knowledgeable collectors. It says “I know more about Rolex than you do.”
- Value: At $3,000-$6,000 for a steel Datejust Oysterquartz, it’s the cheapest way to own a Rolex with a sapphire crystal, 904L steel, and Cyclops lens.
Frequently Asked Questions
Is the battery hard to replace?
The Cal. 5035/5055 uses a standard 395/399 silver oxide battery — available at any watch shop. Battery life: 3-5 years. However, Rolex no longer services the Oysterquartz officially (parts support ended around 2015). Independent watchmakers with quartz expertise handle servicing, but finding replacement IC chips if the module fails is increasingly difficult.
Will it appreciate?
Slowly but steadily. Steel OQ Datejusts have doubled from $1,500-$2,500 (2015) to $3,000-$6,000 (2026). The gold Day-Date OQ has appreciated faster. As surviving examples decrease (battery leaks and neglect destroy movements), functional units become rarer.
Is the Oysterquartz a “real” Rolex?
Absolutely. It bears the Rolex crown, uses Rolex 904L steel, sapphire crystal, Cyclops, and was designed by Gérald Genta. Rolex corporate may prefer you forget it exists, but the OQ is as much a Rolex as any Submariner. For alternative Rolex experiences, browse our Datejust collection at DR.WATCH.
