The Rolex Oysterquartz Day-Date is the quartz-powered Day-Date introduced in 1977, fitted with calibre 5055—not the modern self-winding Day-Date with calibre 3255. Its angular case and integrated bracelet set it apart from the rounder automatic models, while references such as the 19018 and 19019 offer a straightforward starting point for understanding the range.
What is a Rolex Oysterquartz Day-Date?
Rolex’s Day-Date family began in 1956. Rolex says the original model was the first calendar wristwatch to display the weekday spelled out in full alongside the date (Rolex Newsroom). The Oysterquartz Day-Date arrived later, in 1977, as a distinct quartz-powered version. Specialist references identify its movement as Rolex calibre 5055 (Oysterquartz.net; Bob’s Watches).

Its design is another defining feature: Sotheby’s describes an angular case paired with a fully integrated bracelet, a strong contrast with the more familiar rounded Day-Date silhouette (Sotheby’s). Bob’s Watches describes the case as 36 mm; that dimension is from its secondary reference guide, not the Rolex Newsroom page.
Is the Rolex Oysterquartz Day-Date automatic or quartz?
It is quartz. Calibre 5055 is the Day-Date Oysterquartz movement; the self-winding calibre 3255 belongs to the current Day-Date specification and should not be applied to this 1977 quartz variant. Oysterquartz.watch reports that calibre 5055 was COSC-certified from introduction and remained unchanged during the variant’s life (Oysterquartz.watch, “Evolution”).

What is the difference between the 19018 and 19019?
The simplest distinction is the case metal: the 19018 is yellow gold and the 19019 is white gold. Both are useful baseline references when comparing Oysterquartz Day-Dates, but they do not represent the full range. Specialist and dealer guides show further configurations involving decorative or gem-set dials, bezels, and bracelets; examples include references 19028 and 19168 as well as 19019 variants (Oysterquartz.watch; Bob’s Watches).
When assessing a specific watch, compare its reference and metal with its dial, bezel, and bracelet configuration. Do not assume an unusual or gem-set example is original based on appearance alone: the sources describe variants, but they do not authenticate individual watches or establish current market values.
How can you tell an early Oysterquartz Day-Date from a later one?
Oysterquartz.watch describes an approximate finishing change around 1985/86. According to that specialist account, earlier cases had horizontal brushing and bevels. Later cases had vertical brushing, lacked those earlier bevels, and used a slightly rounded case-to-bracelet transition; the bracelet finish changed in step with the case (Oysterquartz.watch, “Evolution”).
This is a useful comparison point, not a stand-alone dating or authentication test. The changeover is approximate, and finish can be affected by wear or refinishing. For a particular watch, consider the reference, configuration, originality, service history, documentation, and provenance together, and seek an assessment from a qualified specialist.

When did Rolex stop making the Oysterquartz Day-Date?
The exact final production date is not established by a Rolex-published Day-Date-specific source in the references cited here. Sotheby’s says the Day-Date variant remained available until 2001 (Sotheby’s). Oysterquartz.net estimates that actual production of Oysterquartz watches likely ended in 2001, while steel-and-gold and all-gold watches remained in the catalogue through 2003 as stock was depleted (Oysterquartz.net). Those dates can describe different milestones—production, availability, and catalogue listing—rather than a single confirmed end date.
Oysterquartz.net estimates fewer than 25,000 watches across the Oysterquartz family, including both Datejust and Day-Date models. This is a specialist estimate, not a Rolex-confirmed figure, and it is not a Day-Date-only production count.
Why does the Oysterquartz Day-Date matter to collectors?
It combines the Day-Date’s place in Rolex history with a less common quartz movement and a distinctly angular, integrated-bracelet design. Sotheby’s also notes renewed attention to this design following the 2025 Land-Dweller launch, which it interprets as referencing the Oysterquartz’s design; that is Sotheby’s observation, not an official Rolex statement about design lineage (Sotheby’s).
For a prospective buyer, the practical task is to verify the exact reference and configuration, then evaluate condition, originality, service documentation, and provenance. A reference guide can help identify what to examine, but it cannot establish the authenticity or service status of an individual watch.
