機芯維修保養

The movement is the heart of the watch — from basic cleaning to complication repair.

Lubricants inside a movement dry out and degrade over time, accelerating wear and harming accuracy. Regular servicing extends the life of the movement and helps preserve value.

Frequently asked

How often should a watch be serviced?

Every 3–5 years is typical; more frequent wear or a humid environment may justify a shorter interval. The inspection findings and lubrication condition decide in practice.

Which parts will be replaced?

Only parts that must be replaced — perished seals, worn gears and so on — and each is itemised in the quotation. Sound original parts are never replaced unnecessarily.
