I have a steel Santos that I bought in 1990. I typically take it to Cartier to get the battery replaced. Today I went to the Cartier on Rodeo in Los Angeles. I thought I needed the battery replaced but they informed me that my watch needs "service." The service will cost $345. Has anyone ever gotten their Santos serviced? What does the "service" entail for $345? I told the SA that I would have an answer for her tomorrow on whether to continue or not. I'm thinking of just taking it somewhere else and get the battery replaced!
