Mast tank for routine maintenance requested the other day.
The case material of the Mast series is called "vermeil".
A distinctive material with a gold-plated silver surface.
Discoloration is inevitable due to the material used,
During maintenance, we will remove discoloration and clean the case.
Silver and gold will tarnish when exposed to air or ultraviolet light.
This is something that cannot be avoided, so there is no way around it.
When we sell a watch, we provide you with a polishing cloth containing abrasives.
Many people request that their maintenance watches be kept clean,
Before starting the overhaul work, we clean the case.
When the repair is completed and the product is handed over to the customer,
"It looks so beautiful!" they say delightfully.
If you are used to seeing it before the repair, it may seem like a different item.
If you clean it up after it has become discolored to a certain extent,
It makes it feel like a new watch.
This time, the work was completed as normal maintenance and has already been delivered to the customer.
Now you can use it forever!
