Start with the complete record

Owners frequently receive conflicting advice about service intervals and maintenance. The safest starting point is the manufacturer’s current guidance for the specific watch, followed by an assessment of how that individual watch is performing and being used.

Patek Philippe currently recommends regular service through an official service center or authorized retailer and publishes an eight-to-ten-year interval for quartz and mechanical watches. It also explains that the scope of service depends on the timepiece and its complexity.

Evaluate the specific asset

Audemars Piguet provides official care information, service-request access and an after-sales network. Its public material is most useful for locating authorized support and understanding available manufacturer services; it should not be converted into a universal rule for every reference or condition.

Vacheron Constantin describes repair and restoration as a personalized process, with an estimate based on the individual timepiece. Its care materials also address operation and maintenance topics for movements, bracelets and straps.

Put the evidence into practice

These manufacturers’ guidance supports a balanced ownership policy: document performance, understand water-resistance and use conditions, preserve service records and seek reference-specific advice. Calendar age alone is relevant, but it should not be the only fact considered when deciding the scope or urgency of service.

Practical takeaway

Begin with the manufacturer’s current instructions, then make a reference-specific decision based on performance, use, condition and documented history.
