Regardless of how often you use it.

An overhaul of an Omega De Ville that was requested the other day.

It has been several years since you purchased it,

It seems to be used only when absolutely necessary, so it is used infrequently.

The exterior is in pretty good condition,

Regardless of how often you use your watch, maintenance is necessary.

Since the internal "movement" of a watch is exposed to air,

The machine oil used in the machines will run out.

The frequency of use is minimal, so the amount of machine oil used is reduced.

Dry parts operating together can cause wear and tear.

In the worst case scenario, the movement will stop working.

Therefore, it varies depending on the structure of the watch or machine,

We recommend an overhaul every three years if possible.

This time, we had an overhaul because it hadn't been maintained for a while.

I would be happy if you could contact me again in 3 years.

Even if the watch is sturdy, it still requires maintenance.

Even if it works and has good accuracy now,

Be careful not to underestimate it!
