Q: What is the Cartier Must de Cartier Ronde 28mm watch?
A: It’s a vintage, Swiss‑made quartz timepiece with a refined 28mm gold‑plated silver case (often referred to as vermeil), a cream white dial, and the original Cartier leather strap and buckle. Elegant and understated, it’s ideal for dressy occasions and everyday smart wear on smaller to medium wrists.

Q: Which movement does it use and how long will the battery last?
A: It uses a Swiss quartz movement known for reliability and low maintenance. Typical battery life is around 2–3 years depending on use and storage. Please have a professional confirm the exact battery type for this specific piece.

Q: How do I set the time on this quartz model?
A: Gently pull the crown out to the time‑setting position, turn the hands to the correct time, then push the crown back in firmly. This model is typically time‑only (no date), so there’s no date‑setting step.

Q: Is it water‑resistant and can I wear it in the rain or swim with it?
A: With vintage watches, water resistance cannot be guaranteed without recent servicing and pressure testing. Treat it as splash‑resistant at best and avoid swimming, showering or submersion. Keep the leather strap dry and the crown fully pushed in during light exposure to moisture.

Q: What is the case made of and how should I care for the plating?
A: The case is gold‑plated silver (vermeil). Wipe it with a soft, dry microfibre cloth and avoid abrasive polishes, solvents, perfumes and lotions, which can mark leather and degrade plating. Light scratches are normal on vintage pieces; specialist jewellers can re‑plate if desired.

Q: What type of crystal does it use?
A: Many Must de Cartier Ronde models feature a mineral glass crystal. If you’d like us to confirm the crystal type on this specific watch, please contact us and we’ll verify it for you. Avoid hard knocks and abrasive surfaces to keep the crystal clear.

Q: Will it fit my wrist, and can the strap be changed?
A: The 28mm case wears elegantly on smaller to medium wrists. The original Cartier leather strap is adjustable via the buckle holes. Straps can be swapped; we’re happy to advise on the correct lug width and suitable replacement options.

Q: Does it have a date function or other complications?
A: This Must de Cartier Ronde is typically a time‑only model without a date window, keeping the dial clean and classic. If you need confirmation for this exact piece, we can provide close‑up photos on request.

Q: What servicing should I expect for a vintage quartz watch?
A: Replace the battery every 2–3 years and consider a routine movement check every 5–10 years, or sooner if you notice issues (stopping, condensation). Have seals/gaskets inspected if light moisture resistance is important. Keep the watch away from strong magnets and wipe it clean after wear.
