Q: Is the movement quartz, and does it need winding?
A: Yes—this Tank Solo uses a battery-powered Swiss quartz movement. It does not require winding. When the battery runs low, the seconds hand may start stepping irregularly or stop; a simple battery replacement will restore normal function.

Q: How do I set the time on this watch?
A: Gently pull the crown out to the time-setting position and turn it anti-clockwise or clockwise to set the hands. Push the crown back in firmly when finished. This model is typically time-only (no date), so there’s no date-setting step to worry about.

Q: Which battery does it use and how long will it last?
A: Many Cartier quartz Tank models use a 1.55V silver-oxide cell such as 377/SR626SW, but please have a professional confirm the exact battery for this specific piece. Typical battery life is around 2–3 years depending on use and storage. We recommend battery changes by an authorised watchmaker to avoid case/dial damage and to maintain seals.

Q: Is it water-resistant and can I wear it in the rain?
A: As a pre-owned/vintage watch, water resistance cannot be guaranteed without recent gasket replacement and pressure testing. Treat it as splash-resistant at best. Avoid swimming, showering or submersion, and always ensure the crown is fully pushed in. If you need moisture protection, have it professionally tested before exposure to water.

Q: What type of crystal and crown stone does it have?
A: Tank Solo models typically feature a scratch-resistant sapphire crystal, though specifics can vary; we can confirm the crystal type on this exact watch upon request. The crown is set with Cartier’s signature blue synthetic cabochon (commonly synthetic spinel), adding a refined touch.

Q: What accuracy and maintenance should I expect from a quartz Tank Solo?
A: A healthy Swiss quartz watch typically keeps excellent time (often within ±15–30 seconds per month), though performance can vary with age and battery condition. Replace the battery every 2–3 years, have gaskets checked periodically, keep the watch away from strong magnets, and wipe the case/strap with a soft microfibre cloth. For leather, avoid prolonged moisture, perfumes and oils, and store away from heat and sunlight.
