The Cartier Must Series is very popular at our shop.
This popular item has been handled since the shop opened and has been loved by many customers to this day.
This series uses silver 925 for the case material and is plated with 18k gold on the surface,
This uses a technique called "Vermeil".
Due to the nature of the material, silver oxidizes and turns black when exposed to air,
Gold turns purplish-blue due to the effects of ultraviolet rays and other factors.
This is unavoidable as long as air and ultraviolet rays exist,
There is probably no way to prevent discoloration with modern technology.
The production of all Must Series items ended around 2004,
For cases with gold plating, including those from other brands, the labor cost for craftsmen is very high,
I hear that it was not economically viable as a wristwatch.
Also, even if it was manufactured at high cost, discoloration was unavoidable, and many complaints are presumed to have occurred,
It is thought that Vermeil materials are no longer used for various reasons.
Wristwatches allow us to feel the historical background of each era,
Various considerations can be made not only from the watch's design but also from its materials,
I always believe that this also creates documentary value.
However, even if discoloration is unavoidable,
Suggesting methods for users to deal with it themselves,
I believe this is the role of stores that handle such products.
When you purchase a watch from the Must Series at our store,
We provide a polishing cloth containing abrasive.
It's a cloth for polishing silver, so it's the same as what's available commercially,
Currently, the only way for users to deal with it themselves is
There is no other way than to polish it with this polishing cloth.
Considering the nature of the material, I think it's the best choice,
On the other hand, there are a certain number of people who consider discoloration and the peeling of the surface gold plating to be part of the "character",
We hope the owner will determine the best solution for themselves.
However, we will provide as much support as possible,
Please feel free to contact us if you have any questions.
