# Watch Service Interval Tracker: Know When to Service Your Watches
A mechanical watch is a precision instrument with hundreds of moving parts. The lubricants dry out, gaskets degrade, and the rate drifts over time. Keeping track of when each watch was last serviced and when it is next due is the single most important habit for any collector. This tracker helps you stay on top of maintenance across your entire collection.# Why Service Intervals Matter
- Automatic (3-5 years)
- The mainspring barrel, reverser wheels, and rotor bearing experience constant wear. Old oil turns gummy and accelerates component wear.
- Manual (3-5 years)
- Similar interval to automatics. The crown stem and keyless work endure repeated winding cycles.
- Quartz (5-10 years)
- Fewer moving parts but the battery can leak, and gaskets still need replacing to maintain water resistance.
- Kinetic (5 years)
- Combines automatic winding with quartz timekeeping. The capacitor or battery has a finite lifespan.
