Cartier refuses to service watches sent to their facilities by independent watchmakers, on behalf of consumers.

Cartier's goal is not quality but eliminating the competition. It is obvious that if quality was the reason to refuse to supply, they would be happy to perform servicing for everybody.

It is obvious that being able to work at approximately $3,000 per hour wouldn't be possible by servicing watches sent by watchmakers!!!!

Monopoly at work and at the expenses of the consumers.
Cartier monopoly also applies to consumers!!
Watch Servicing Competition
Keep Prices and Quality in Check
