Battery Change vs Full Service: What's the Difference?
A battery change is exactly what it sounds like — the old cell comes out, a new one goes in. It takes under two minutes and addresses one specific cause of a stopped watch: no power.
A service is a complete mechanical overhaul. The movement is removed from the case, disassembled, cleaned, lubricated, reassembled, regulated for accuracy, and pressure-tested. It addresses wear, contamination, degraded lubricants, and moisture damage — problems that no battery can fix.
The rule of thumb: If your watch stops and the battery is more than 2 years old, try a fresh battery first. If the battery is less than 2 years old — or if the same problem keeps coming back — the movement needs attention.
The 5 Signs Your Watch Needs a Service
It loses time with a fresh battery
If your watch was accurate before but now gains or loses more than 15–30 seconds per day — despite a recent battery change — the oscillator or regulator inside the movement is the problem. Degraded lubricants cause friction that slows the movement down and creates inconsistent timekeeping that no battery can fix.
The crown feels gritty, stiff, or loose
The crown connects to the stem, which engages the movement's setting mechanism. Gritty resistance when pulling the crown out or turning it to set the time indicates contamination inside the case or a worn stem tube. A loose crown that rattles or moves sideways suggests the stem or tube is damaged. Neither issue resolves itself.
The crystal has fogged up inside
Condensation under the crystal means moisture has entered the case. Even if the fogging clears — which happens as temperature changes — the damage is ongoing. Water accelerates corrosion on movement components and degrades lubricants. A watch that has fogged once needs the movement cleaned and dried, and the gasket replaced, regardless of whether it's currently running.
It runs fine for a while, then stops without warning
Intermittent stopping — particularly when the battery is known to be good — points to a faulty electrical contact, a worn rotor bearing (in automatic watches), or contamination on the movement's circuit board. Each time the watch stops and restarts unexpectedly, it confirms a mechanical or electrical fault rather than a power issue.
It hasn't been serviced in over 5–7 years
Lubricating oils inside watch movements are not permanent. Over 5–7 years they degrade, migrate away from the surfaces they protect, or dry out entirely. A movement running on depleted lubrication accumulates wear on pivots and jewels even when it appears to be working correctly. Preventive servicing at this interval is significantly cheaper than repairing worn parts.
Don't wait for it to stop completely. A watch running with degraded lubricants or a damaged gasket causes progressive wear with every hour of use. The longer a service is delayed, the more components may need replacing rather than just cleaning.
What Does a Professional Watch Service Involve?
A full watch service is a multi-step process. Here's what happens:
-
1Case disassembly — the movement is removed from the case. The bracelet or strap, crown, and case back are set aside. The condition of the gasket is assessed; it is replaced as standard.
-
2Movement disassembly — the movement is taken apart component by component. All parts — gear train, escapement, keyless work, dial train — are separated and laid out for inspection.
-
3Cleaning — parts are cleaned in specialist solutions to remove old lubricants, corrosion deposits, and contamination. Ultrasonic cleaning is used where appropriate to reach recesses that manual cleaning cannot.
-
4Inspection and parts replacement — every component is examined under magnification. Worn, corroded, or damaged parts are identified and replaced. Common replacements include gaskets, worn pivots, damaged click springs, and corroded battery contacts.
-
5Lubrication and reassembly — specific lubricants are applied to specific surfaces — gear pivots, the escapement, keyless work, and the crown stem tube each require different viscosities. The movement is then reassembled.
-
6Regulation and testing — the reassembled movement is regulated for accuracy and tested across multiple positions. Quartz movements are verified electronically; mechanical movements are tested on a timing machine.
-
7Case reassembly and pressure test — the movement is fitted back into the case with a fresh gasket. For water-resistant watches, a pressure test confirms the seal is intact before the watch is returned.
How Often Should Different Watches Be Serviced?
| Watch Type | Recommended Service Interval | Key Reason |
|---|---|---|
| Quartz (time only) | Every 5–7 years | Lubricant degradation, gasket hardening |
| Quartz (chronograph / complications) | Every 4–5 years | More moving parts = more wear surfaces |
| Mechanical / automatic | Every 3–5 years | Oils degrade faster under constant movement |
| Any watch exposed to moisture | Immediately | Corrosion begins within hours of water entry |
| Any watch stored unused for 2+ years | Before wearing | Dried lubricants cause immediate wear on restart |
Quartz vs Mechanical: Different Needs, Same Principle
Quartz watches have fewer moving parts than mechanical watches, but they're not maintenance-free. The lubricants in a quartz movement protect the gear train that drives the hands, the keyless work (the mechanism that lets you set the time), and the rotor in automatic-quartz hybrids. These lubricants degrade on the same timeline as in mechanical watches.
Mechanical and automatic watches run on a continuous interaction of gears, levers, springs, and jewels — a system that relies entirely on precise lubrication to function without wearing itself out. An automatic watch worn daily is particularly prone to lubricant degradation because the rotor is in near-constant motion.
Practical tip: If you have multiple watches and rotate them, each still ages internally at its own rate regardless of wearing frequency. A watch sitting unworn in a drawer for three years still needs a service inspection before regular use — the lubricants will have migrated and partially dried, regardless of movement.
