Rolex Submariner 40mm White Mark II Ref 1680 1979 Watch

Q: What is the Rolex Submariner Ref. 1680 (1979) offered here?
A: It’s a vintage, Swiss‑made Submariner Date with a 40mm stainless‑steel Oyster case, a White Mark II “Maxi” dial, and an original period‑faded “ghost” bezel insert. It comes on a stainless‑steel Oyster bracelet (Ref. 93150 with 580 end links). Serial 5832277 dates it to 1979. Delivered with no accessories as stated.

Q: What does “White Mark II Maxi dial” mean and how does it differ from a “Red Sub”?
A: Early 1680s featured “SUBMARINER” printed in red (“Red Sub”). Later “White” dials (like this one) have all text in white. The “Maxi” designation refers to larger hour plots for enhanced legibility. “Mark II” identifies a specific late‑1970s dial variant known to collectors by its font and layout details.

Q: Which movement does it use and what is the power reserve?
A: 1680 Submariner Date models typically house the automatic Rolex Calibre 1575 (date). Late‑1970s examples generally feature hacking seconds. The movement does not have a quickset date. Power reserve is around 48 hours. We can confirm specifics for this watch on request.

Q: How do I wind and set the time/date safely on a non‑quickset 1680?
A: Unscrew the crown anti‑clockwise. Position 1: wind (about 20–40 turns if stopped). Position 2: set the time. The date advances by rolling the hands past midnight; repeat as needed to reach the desired date. Avoid changing the date between roughly 8pm and 2am. When finished, push the crown in and screw it down firmly.

Q: Is it water‑resistant and suitable for swimming or diving?
A: The 1680 was originally rated to 200 metres (660 ft). With vintage pieces, water resistance cannot be guaranteed without recent servicing and pressure testing. We recommend avoiding swimming or submersion unless the gaskets have been replaced and the watch has been professionally tested. Always ensure the crown is fully screwed down before any moisture contact.

Q: Does it have an acrylic or sapphire crystal, and does it feature the Cyclops?
A: The 1680 Submariner Date is fitted with an acrylic “top‑hat” crystal and Rolex’s Cyclops magnifier over the date. Acrylic can pick up light marks; many owners use a specialist polish (e.g., Polywatch). Avoid abrasive cleaners and harsh chemicals.

Q: What is a “ghost” bezel and is it original to this watch?
A: A “ghost” bezel refers to a naturally faded bezel insert that has turned a grey/silver tone over time due to UV and wear—highly prized by many collectors. This listing notes the original ghost bezel insert. If preferred, era‑correct inserts can sometimes be sourced and fitted by a professional.

Q: Will it fit my wrist, and can the bracelet be resized or swapped?
A: As listed, it fits a wrist of approximately 18cm or smaller. The 93150 Oyster bracelet can be sized via links and clasp micro‑adjustment; additional links may be sourced subject to availability. The 1680 typically has 20mm lugs, so compatible straps/bracelets should match that width and correct end‑link type.

Q: What does “unpolished case” mean and why do collectors value it?
A: An unpolished case retains its original factory lines and bevels, showing honest wear rather than re‑finishing. Many collectors prefer this originality. If you ever choose to refinish, use an experienced watchmaker to preserve the case geometry.

Q: Is it authentic, and what warranty/shipping do you offer?
A: A Retro Tale rigorously authenticates every item and guarantees 100% originality. This watch is delivered with no accessories unless stated. All watches include a 12‑month mechanical guarantee. We offer free, fully insured DHL shipping, a 14‑day return policy, and 0% customs fees for EU buyers. On request, we can share additional photos and verify reference/serial details (the ref/serial are typically stamped between the lugs).
