Rolex Lady-Oyster Perpetual Date 26mm Ref 79160 Full Set Watch

Q: What is the Rolex Lady‑Oyster Perpetual Date 26mm Ref. 79160?
A: It’s a classic ladies’ Rolex in stainless steel with a 26mm Oyster case, automatic self‑winding movement and a date display under the Cyclops magnifier. This example features a pink dial and comes as a complete full set (original box, certificate and hang tags). The serial K423574 dates it to around 2001.

Q: Which movement does this reference use?
A: Most early‑2000s examples of ref. 79160 are powered by the Rolex automatic calibre 2235 with a quickset date. Some earlier pieces used the calibre 2135. If you’d like, we can confirm the exact calibre fitted to this watch.

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. We recommend avoiding swimming or showering unless the watch has been freshly serviced, re‑sealed and pressure‑tested. Always ensure the crown is fully screwed down before any exposure to moisture.

Q: How do I set the time and date?
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. After setting, push the crown in and screw it down firmly.

Q: Does this watch have a sapphire crystal and Cyclops?
A: Most ref. 79160 models from this era feature a scratch‑resistant sapphire crystal with the Cyclops date magnifier. We can confirm the crystal type on this specific piece upon request.

Q: What wrist size will the 26mm case suit, and is it unisex?
A: The 26mm case offers a petite, elegant profile ideal for small wrists. Although historically marketed to women, it can be worn unisex depending on personal style preference.

Q: Can the bracelet be resized, and what is the current length?
A: Yes, we can size the stainless steel bracelet for your wrist before shipping. This bracelet fits up to approximately 17–17.25cm as currently configured. Additional links may be sourced subject to availability and potential cost—contact us with your wrist measurement for guidance.

Q: What accuracy and service interval should I expect?
A: A well‑maintained Rolex automatic calibre should keep time near the chronometer standards of its era (around −4/+6 seconds per day). Service every 5–10 years is typical, or sooner if you notice timekeeping issues, moisture, or reduced water resistance.

Q: How can I verify the production year and reference details?
A: The K‑prefix serial (K423574) indicates production around 2001. The reference 79160 denotes a stainless steel model with a smooth (domed) bezel. Reference and serial numbers are engraved between the lugs; we can verify and provide additional photos on request.

Q: What is included, and how do you guarantee authenticity?
A: This watch is delivered as a full set—original Rolex box, certificate and hang tags. A Retro Tale authenticates every item, our watches are 100% original, and we include a 12‑month mechanical guarantee with secure, insured delivery.
