Cartier Tank Française Large Model

28 mm X 32 mm · Automatic · 1990s

Introduced in 1996, the Tank Française revolutionized the Tank family by seamlessly integrating a curved case onto a link bracelet. This specific reference is a highly sought-after execution in solid 18k yellow gold, featuring a date window at the 6 o'clock position. The example shown has been paired with a textured blue lizard/exotic leather strap rather than its traditional full gold bracelet.

Box and papers. Where a piece includes them, the listing says so. If they are not mentioned, please assume they are not supplied — ask us and we will confirm exactly what accompanies this watch.

Winding & servicing

  • An automatic movement winds itself through the motion of your wrist. Worn daily, it will keep running; left idle it will stop after roughly 40–48 hours and simply needs a gentle shake or 20–30 manual turns of the crown to restart.
  • A watch winder is optional. If you use one, choose a low rotation setting — continuous high-speed winding adds needless wear.
  • Plan a full service every 5–7 years. A movement that is losing or gaining more than a few seconds a day, or that sounds gritty when wound, should be seen sooner.

Daily wear

  • Avoid operating the crown or pushers while the watch is wet, and always ensure the crown is fully pushed in (or screwed down) before contact with water.
  • Remove the piece before swimming in chlorinated or salt water, using a sauna or hot tub, and before contact sport or manual work. Sudden temperature change and impact are the two things a fine movement tolerates least.
  • Keep it away from strong magnets — laptop speakers, tablet covers, handbag clasps and induction hobs are the usual culprits. Magnetisation shows up as a watch suddenly running fast, and is easily reversed by a watchmaker.

Cleaning

  • Wipe the case and bracelet with a soft, dry microfibre cloth after each wear to lift skin oils and dust before they build up in the joints.
  • Keep the leather strap dry. Leather and water are not friends: repeated wetting causes the strap to stiffen, crack and eventually separate at the stitching. A well-worn strap is a consumable — plan on replacing it every 1–2 years of regular wear.
  • Gold is a soft metal and will pick up fine hairline marks with wear. This is normal and part of the character of a worn piece; a professional polish can reduce them, but every polish removes a little material, so it is best done sparingly.
  • Never use ultrasonic cleaners, solvents, or commercial jewellery dips at home on a watch — they can strip lume, degrade gaskets and damage set stones.

Storage

  • Store in a dry place at stable room temperature, away from direct sunlight — prolonged UV fades dials and ages strap leather.
  • Keep pieces separated in a lined box or soft pouch so cases and stones cannot rub against one another. Diamond is hard enough to scratch virtually anything it shares a drawer with.
  • Retain any documentation supplied with the piece — provenance materially affects resale value.

Water resistance

  • Water resistance is a seal condition, not a permanent specification. Gaskets harden and shrink with age, so a rating stamped on the case back decades ago tells you little about the watch today.
  • Have the case pressure-tested annually, and always after the case back has been opened for any reason.
  • Vintage pieces should be treated as not water resistant regardless of their original rating.
