Q: What are the key details of the Rolex Oyster Perpetual Date ref. 6516?
A: It is a vintage ladies’ Rolex with an Oyster case around the mid‑20s in diameter (this piece measures 25 mm), an automatic Perpetual movement and a date at 3 o’clock. Period examples commonly feature an acrylic crystal and a screw‑down crown for everyday durability.

Q: Is the date quickset on this reference?
A: Most ref. 6516 models are non‑quickset, meaning the date changes when the hands pass midnight. To set the date, pull the crown to the time‑setting position and advance the hands past 12 o’clock repeatedly until the correct date shows. Avoid changing the date during the typical “danger zone” of about 8 pm to 4 am to help protect the mechanism.

Q: How water‑resistant is a vintage Oyster case like this today?
A: The Oyster case was designed for water resistance, but on a vintage watch water resistance is not guaranteed. Only a recent service and pressure test can confirm it. Keep the crown fully screwed down, and avoid swimming, showers, or saunas unless the watch has been tested and rated by a watchmaker.

Q: How do I wind and start it if it has stopped?
A: Unscrew the crown, then turn it clockwise about 30–40 times to fully wind the mainspring. Push the crown back in and screw it down snugly. Normal wrist movement will keep the automatic movement running thereafter.

Q: Which movement does the 6516 typically use?
A: Many period examples of the 6516 are fitted with Rolex’s automatic calibre 1161 (26 jewels). As with most vintage references, movement calibre can vary slightly by year and configuration.

Q: What strap size fits, and can I change the strap?
A: Many 6516 cases have an approximate 13 mm lug width. This watch is supplied on a black leather strap, and a professional can fit alternative leather, rubber, or bracelet options to suit your wrist and style. As tolerances can vary with vintage pieces, measuring between the lugs is recommended before ordering a new strap.

Q: What is included with this watch?
A: According to the product information, the watch is supplied as shown on the leather strap. Original box, papers, or extras are not included unless specifically listed under product information.

Q: From what era is the ref. 6516, and can you date this specific piece?
A: The 6516 was produced mainly in the 1960s to early 1970s. The exact production year of an individual watch is usually estimated from its serial number, engraved between the lugs at 6 o’clock; this listing does not display a serial number. Our team can help with dating once the number is available.

Q: Is the crystal acrylic and how should I care for it?
A: Many 6516 examples use an acrylic (plexi) crystal. Light surface scuffs on acrylic can often be improved with a specialised acrylic polish; deeper marks or chips should be assessed by a watchmaker. Avoid abrasive household cleaners on the case and crystal, and store the watch dry and away from strong magnets.

Q: How does A Retro Tale handle authenticity and condition?
A: Every piece is vetted by our in‑house experts through multi‑point checks of case, dial, crown, movement and engravings. Condition is described transparently; for this watch, expect very good overall condition with noted scratches on the case and case back as per the listing. Additional photos or a detailed condition report are available on request.
