Q: What is the Rolex Datejust 36mm Ref. 16233 (1988)?
A: It’s a classic two‑tone Datejust featuring a 36mm stainless steel and 18k yellow gold Oyster case with a fluted bezel, champagne dial, automatic movement, and the signature date with Cyclops magnifier. This example is a vintage piece from 1988.

Q: Which movement does the 16233 use, and is the date quickset?
A: Most Datejust 16233 models are powered by the Rolex Calibre 3135 automatic movement, known for robustness and accuracy. It features hacking seconds and a quickset date for easy adjustment.

Q: Does this model have a sapphire crystal and Cyclops?
A: Yes. The 16233 typically has a scratch‑resistant sapphire crystal with Rolex’s Cyclops magnifier over the date for improved legibility.

Q: Is it water‑resistant and can I swim with it?
A: The Oyster case was originally rated to 100 metres, but water resistance on vintage watches cannot be guaranteed without recent servicing and pressure testing. We recommend avoiding swimming or showering unless the seals have been replaced and the watch tested by an authorised watchmaker. Always ensure the crown is fully screwed down before any exposure to moisture.

Q: How do I set the time and date on a Datejust 16233?
A: Unscrew the crown anti‑clockwise. Position 1: wind the watch (around 20–30 turns if stopped). Position 2: quickset the date. Position 3: set the time. Avoid changing the date between approximately 8pm and 2am to protect the mechanism. When finished, push the crown in and screw it down firmly.

Q: What strap or bracelet does this piece come with, and can I fit a Jubilee or Oyster bracelet?
A: This watch is fitted with a brown aftermarket leather strap with a generic buckle. The ref. 16233 has a 20mm lug width, so OEM Rolex Jubilee or Oyster bracelets for this reference can be fitted; sourcing is subject to availability and may incur additional cost. Contact us for guidance.

Q: What wrist size does 36mm suit, and is it unisex?
A: The 36mm Datejust offers a timeless, balanced presence that suits many small to medium‑large wrists and is widely worn unisex. If you’d like fit advice or strap options, share your wrist measurement and we’ll assist.

Q: How can I confirm the production year and reference of this watch?
A: The reference number is typically engraved between the lugs at 12 o’clock and the serial at 6 o’clock (the strap/bracelet must be removed). This piece has an R‑prefix serial (R886555), consistent with 1988 production. We can verify details and provide photos on request.

Q: What accuracy and service interval should I expect?
A: A well‑maintained Calibre 3135 can keep time close to period COSC standards (around −4/+6 seconds per day), though performance varies with age and service history. A routine service every 5–10 years is commonly recommended, or sooner if timekeeping or water resistance is a concern.

Q: What is included and do you offer a warranty and authenticity guarantee?
A: As listed, this watch is delivered with a Rolex service guarantee card dated 2020. A Retro Tale thoroughly inspects and authenticates every item and provides a 12‑month mechanical guarantee on all watches. Please refer to the Accessories section and images for exactly what is included.
