# Movement service

This refers to the complete maintenance and servicing of a watch's internal mechanism, or movement. It typically involves disassembling the watch, cleaning all components, lubricating pivots and gears with specialized oils, and ensuring all parts are functioning precisely according to the manufacturer's specifications. For collectors and resellers, a documented, professional movement service is crucial because it confirms the watch is running accurately and reliably. A well-serviced watch commands a higher price because it assures the buyer of its operational integrity and longevity. Conversely, a watch with an unknown or neglected movement carries significant risk. Always request the service history documentation from the seller.

## What it means
Movement service is the complete overhaul of a watch's mechanical heart—the movement. This goes beyond a simple battery change. It involves complete disassembly, ultrasonic cleaning of all components, meticulous inspection for wear or damage, replacement of worn parts (like gaskets or springs if necessary), and the precise re-lubrication of every pivot and gear using manufacturer-specified oils. The mainstream equivalent is professional watch repair. For collectors and resellers, this service confirms the watch is operating within factory tolerances, ensuring accuracy and reliable function. It is not merely cosmetic; it is functional integrity.

## What it does to price
A documented, recent, professional movement service adds tangible value. A watch that has been serviced within the last 2-3 years typically commands a premium of 8% to 15% over an identical, unserviced counterpart, assuming the service was performed by a reputable firm. If the service involved a full overhaul (not just a cleaning), the premium can approach 20%. Conversely, a watch with known, documented neglect or an unknown service history carries a discount risk of 10% or more, as the buyer assumes the risk of immediate failure. For example, a $1,500 watch with recent service documentation might sell for $1,650, whereas the same watch with no service history might sell for $1,350.

## How to spot it
Evidence of service is usually found in documentation, not on the watch itself. Sellers must provide a service record or invoice from a recognized watchmaker. Look for evidence of correct caseback screws or movement finishing—a poorly reassembled movement shows signs of amateur work (e.g., visible debris under the bridges or incorrect oil viscosity). A common honest mistake is having only a "cleaning" done, which is not a full service and warrants a lower price adjustment. Be wary of sellers who claim "freshly serviced" without providing any supporting paperwork.

## Buying smart
Paying a premium for service is justified when the watch is a high-value piece (over $3,000) or when the watch is rare and its operational status is critical to its desirability. If the watch is entry-level or common, the cost of the service itself may outweigh the market premium. A fair deal involves a documented service history matching the watch's expected service interval (typically every 5-10 years for mechanical pieces). If the seller provides proof of service but the watch still exhibits poor timekeeping, the premium is unwarranted.

## Selling smart
Proving a recent, professional movement service is the single most effective way to justify a higher asking price. The premium is earned through verifiable trust. The one element that secures this premium is the clear, high-resolution photograph of the service invoice, showing the watch's serial number matching the documentation. Listing the watch as "Recently Serviced" and including the service receipt elevates the watch from an "untested item" to a "verified running machine," immediately narrowing the pool of interested buyers to those prioritizing immediate usability.
