マストシリーズのケース変色の際の対応。

What to do when the Mast Series case discolors.

A must-have series of Cartier vintage models that are extremely popular.

It features a luxurious material with gold-plated sterling silver on the surface,

Silver and gold will tarnish due to exposure to air and ultraviolet rays.

As you can see, discoloration of the case occurs over time, and this cannot be avoided.

This is not a problem with the watch itself, but rather a problem with the nature of the material itself.

There is currently no technology that can prevent silver and other metals from tarnishing.

Metal sulfidation occurs in the same way as molecular bonding that we learned about in science class.

So if it gets discolored, you'll need to take care of it.

When we sold the Must Series watches,

We provide a polishing cloth to deal with discoloration of the case.

This cloth contains abrasives, so you can remove discoloration by lightly polishing it with it.

There is no need to panic if the case becomes discolored, as you can simply lightly polish the discolored areas to make them look nice.

Although discoloration of the case is unavoidable due to the nature of the material, it is still a major concern for users.

It's no big deal if you just know how to deal with it.

When you request a watch battery replacement or overhaul repair from us,

We will also clean the case along with removing discoloration,

If you want to clean up the discoloration on your watch, please feel free to contact us!
