In short: Send us photos of your Cartier, its dial, crown and any papers, or arrange to bring it to Spyrou Merkouri 4, Pangrati, Athens. Our master watchmaker checks the secret signature, cabochon, hallmarks and movement in person, then we explain a market-referenced offer and pay immediately if you accept. The valuation is free.
Cartier sits where fine watchmaking meets jewellery, and that changes how it is valued and sold. A Tank or a Santos can be a serious collector’s watch, a quartz everyday piece, or a gold-and-diamond jewel — and those are priced on entirely different logic. Add the fact that Cartier is one of the most copied names in the world, and it becomes clear why selling to someone who actually knows the brand matters. This page explains what your Cartier is worth and how a sale works with us in Athens.
What determines the value of my Cartier?
- The model and era. Tank (Louis Cartier, Cintrée, Américaine, Française, Must, Solo), Santos, Ballon Bleu, Panthère and Pasha each have their own market. Vintage and rarer pieces — early Tanks, London-made Cartier, and the Crash above all — command significant premiums.
- Quartz or mechanical. Many Cartier watches are quartz, and that is entirely normal for the brand — but it changes the value and the buyer. A mechanical Tank and a quartz Tank are different products; we price each honestly for what it is.
- Metal and stones. Gold weight matters, and here is a detail owners often get wrong: factory-set diamonds add value, but aftermarket stones usually reduce it to a serious buyer. If your Cartier has been “upgraded” with non-original diamonds, that is part of the honest conversation.
- Originality and authentication. The genuine article hides a secret signature in a Roman numeral, wears a correct crown cabochon, and carries proper hallmarks. These are exactly what a specialist checks — and exactly where fakes and “married” watches give themselves away.
Box, papers and any service history complete a full set and help the sale.
Where should I sell my Cartier: specialist, marketplace or pawn shop?
A pawn shop or generalist jeweller will value your Cartier as gold and stones and miss its collector value entirely — a real risk with a vintage Tank or a Crash. A marketplace exposes you to the brand’s enormous counterfeit problem, where convincing fakes fool photographs routinely. A specialist authenticates in person — secret signature, cabochon, movement — values the watch correctly whether it is a collector piece or a jewel, pays immediately, and carries the risk.
We buy Cartier outright and also trade against pieces in our collection.

Frequently asked questions
Is a quartz Cartier worth selling?
Yes — a quartz Tank or Panthère is a genuine Cartier and has a real market. It is valued differently from a mechanical piece, and we price it honestly for what it is.
My Cartier has added diamonds — does that help or hurt?
It depends on whether they are factory-set or aftermarket. Original factory stones add value; non-original ones usually reduce it to a serious buyer. We will tell you which you have.
How do you know it is genuine?
Because we check it in person — the secret signature, the cabochon, the hallmarks and the movement — not from a photograph. Cartier is heavily counterfeited, and in-person authentication is exactly what protects your sale.
Do you service Cartier?
Yes, with a written two-year warranty and original parts only. We are an independent specialist, not an authorised Cartier service centre; a watch under factory warranty belongs with the official network first.
