The Real Cost of Owning a Mechanical Watch (Service Intervals Explained)
Beyond the purchase price, a mechanical watch typically needs a full service every 3-7 years, plus occasional gasket replacement to preserve water resistance, and strap or bracelet maintenance over time — ongoing costs a quartz or smartwatch owner largely avoids.
Frequently Asked Questions
Do quartz watches need the same servicing?
No — quartz watches mainly need periodic battery replacement, a far smaller and less frequent cost than a full mechanical service.
What happens if I never service an automatic watch?
It will likely keep running for a while, but accuracy typically degrades and the risk of a costly repair from accumulated wear increases the longer service is delayed.
What a full service actually involves
A full mechanical service typically involves fully disassembling the movement, cleaning each component, replacing worn parts (such as gaskets and mainspring if needed), re-oiling, reassembling, and regulating the movement back to accuracy specifications.
Neglecting service for too long can allow old lubricant to gum up or dry out, increasing wear on gear teeth and pivots, which can turn a routine service into a more expensive repair.
Budgeting for ongoing ownership
A realistic budgeting approach sets aside a service fund proportional to the watch's value, since service costs scale with movement complexity and brand rather than staying flat across the market.
Water-resistance pressure testing, often bundled with routine service, is a smaller recurring cost worth tracking separately if you wear a watch swimming or in wet conditions regularly.
