Q: What are the exact dimensions of this Tank Solo 3169?
A: The large model Tank Solo in steel measures approximately 34.8 mm x 27.4 mm with a slim 5.55 mm profile. Rectangular cases tend to wear larger than their width suggests, so it suits many wrists while remaining elegantly low‑profile under sleeves.

Q: Which references does 3169 correspond to?
A: Cartier’s numeric ref 3169 denotes the large steel Tank Solo with a quartz movement. It is commonly paired with market codes such as W5200014 (usually on steel bracelet) and W5200003 (typically on leather). The core case and movement specifications are the same across these references.

Q: What movement does it use and how long does the battery last?
A: It houses Cartier’s quartz calibre 690. Under normal use, Cartier advises an average battery life of around three years; have the battery replaced by a Cartier boutique or authorised service so water‑resistance is checked and seals are renewed as needed.

Q: Is it water‑resistant and can I swim with it?
A: The large Tank Solo is rated to 3 bar/30 metres. This is suitable for daily splashes and rain but not for swimming, showering or sauna use. Always ensure the crown is fully pushed in, and have water‑resistance checked periodically—especially after a battery change.

Q: What crystal and crown does it have?
A: The watch features a scratch‑resistant sapphire crystal and a beaded crown set with a synthetic cabochon‑shaped blue spinel—the signature Cartier touch.

Q: Can I change the strap? What is the lug width?
A: Yes. The large Tank Solo uses a 20 mm lug width with conventional spring bars (this model does not use Cartier’s QuickSwitch system). It ships here on a black leather strap; you can fit Cartier straps or quality third‑party 20 mm options to personalise the look.

Q: Is the Tank Solo still in production?
A: The Tank Solo line has been discontinued and succeeded by the Tank Must in 2021. Availability of Solo models is now primarily through the pre‑owned market, which is why well‑kept examples are sought after.

Q: What is included with this specific watch?
A: Everything included is listed under product information for this item. For this piece, the Cartier box is included. If an item like a warranty card or manual is not listed there, it is not included—our team is happy to confirm details.

Q: How should I maintain a quartz Tank Solo?
A: Expect a battery replacement roughly every three years and a periodic functional check with Cartier about every six years. Avoid water exposure beyond everyday splashes, keep leather away from moisture and cosmetics, and wipe the watch with a soft cloth before storing it.
