Q: What is the Jaeger‑LeCoultre Reverso 20mm Ref. 261.8.86?
A: It’s a vintage, Swiss‑made manual‑winding wristwatch in stainless steel featuring the Reverso’s signature rectangular, reversible case (20mm width) and a rare black dial with Arabic numerals. Elegant and compact, it embodies the classic Reverso aesthetic and craftsmanship.

Q: How does the reversible case work and what’s its purpose?
A: The Reverso was originally designed so polo players could flip the watch to protect the dial. To operate: gently slide the case along its carriage until it releases, rotate it 180°, then slide it back until it clicks and locks flush. Don’t force the mechanism; keep the rails clean and have a professional inspect it if the action feels stiff.

Q: What movement does it use, and how should I wind it?
A: This model has a manual (hand‑wound) Jaeger‑LeCoultre movement. Wind it by turning the crown clockwise—about 20–40 turns if it has stopped—until you feel increased resistance. Do not force it beyond that point. Regular daily winding at roughly the same time helps maintain consistent timekeeping.

Q: How do I set the time safely?
A: Pull the crown out gently to the time‑setting position and turn the hands to the desired time, then push the crown back in firmly. This example is a time‑only Reverso (no date), so there’s no date‑change precaution required.

Q: Is it water‑resistant and can I swim with it?
A: As a vintage watch, water resistance cannot be guaranteed without recent servicing and pressure testing. Treat it as splash‑resistant at best and avoid swimming, showering or submersion. Always ensure the crown is fully pushed in before any exposure to moisture.

Q: What type of crystal does it have?
A: Many Reverso models are fitted with a scratch‑resistant sapphire crystal, though specifics can vary by era and reference. If you’d like us to confirm the crystal type on this exact piece, please contact us and we’ll verify it for you.

Q: Will the bracelet fit my wrist, and can it be resized or swapped for a strap?
A: The stainless‑steel bracelet fits wrists up to approximately 17cm as listed. It can be resized by adding/removing links; extra links may be sourced subject to availability. Some Reverso models can be converted to JLC leather straps with the correct end‑links—contact us for compatibility and fitting advice for this specific reference.

Q: Can the reverse side be engraved?
A: Many Reverso owners personalise the solid reverse side with engraving. Suitability depends on the exact case construction and condition. We recommend using an authorised watchmaker/engraver familiar with Reverso cases to avoid damaging the carriage or finish; we’re happy to advise.

Q: What accuracy and service interval should I expect?
A: Performance varies with age and service history, but a healthy manual‑wind JLC should keep good time for its era. A routine service every 5–10 years is generally recommended, or sooner if you notice running fast/slow, reduced power reserve, moisture, or stiff flipping action. Keep the watch away from strong magnets and wipe it with a soft microfibre cloth after wear.

Q: What’s included, and how do you guarantee authenticity and support?
A: This listing is delivered with no accessories unless otherwise stated on the item page. A Retro Tale professionally inspects and authenticates every watch and offers a 12‑month mechanical guarantee, free insured DHL shipping, a 14‑day return policy, and 0% customs fees for EU buyers. On request, we can share additional photos and help confirm movement, reference and serial details for your peace of mind.
