Q: What is the Rolex Datejust 36mm Ref 16234 (2000)?
A: It’s a classic Oyster Perpetual Datejust in stainless steel with a white gold fluted bezel, automatic self‑winding movement, and the signature date display with Cyclops magnifier. This example features a black diamond‑set dial and dates to around the year 2000.

Q: Which movement does the 16234 use, and does it have a quickset date?
A: Most Datejust 16234 models are powered by the Rolex Calibre 3135—an automatic, COSC‑certified movement with hacking seconds and a quickset date. We can confirm the calibre in this specific watch on request.

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 is not guaranteed. Avoid swimming or showering unless the watch has been recently serviced, re‑sealed and pressure‑tested by an authorised watchmaker. Always ensure the crown is fully screwed down before any contact with moisture.

Q: How do I set the time and date on a Datejust with Calibre 3135?
A: Unscrew the crown anti‑clockwise. Position 1: manual wind (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: Does the 16234 have a sapphire crystal and Cyclops?
A: Yes—Datejust 16234 models feature a scratch‑resistant sapphire crystal with the Cyclops magnifier over the date for enhanced legibility.

Q: Will the 36mm size suit my wrist, and is it unisex?
A: 36mm is the classic Datejust proportion that suits many small to medium‑large wrists and wears well unisex. This bracelet fits wrists up to approximately 20cm; we can size it for you, and additional links may be sourced subject to availability.

Q: Can I change the bracelet or fit a leather strap?
A: Yes—the 36mm Datejust typically uses a 20mm lug width. It can be worn on Jubilee or Oyster bracelets, or quality leather straps. For best results and to avoid scratches, have a professional watchmaker handle strap changes.

Q: Are the diamonds on the dial factory Rolex, and how can this be verified?
A: Rolex offered factory diamond‑set dials on the 16234. A Retro Tale professionally authenticates every watch; if you’d like specific confirmation on the dial configuration of this piece, we’re happy to provide details and close‑up photos.

Q: How can I confirm the exact reference and production year?
A: The reference and serial are engraved between the lugs (bracelet removal required). A “P”‑prefix serial typically indicates circa 2000–2001. We can verify these engravings and share supporting photos upon request.

Q: What accuracy and service interval should I expect?
A: A well‑maintained Calibre 3135 typically runs close to COSC standards (around −4/+6 seconds per day), though performance can vary with age and service history. Routine servicing 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?
A: Please see the listing’s Accessories section—this watch is delivered with no accessories unless stated otherwise. A Retro Tale provides a 12‑month mechanical guarantee, an authenticity guarantee, insured DHL delivery, and a 14‑day return policy for peace of mind.
