Different types of servicing

Basic service

A basic service is any operation that does not require disassembly of the movement.

These are:

  • Replacing the crystal
  • Testing or adjusting the watch
  • Polishing
  • Replacing the battery (on a quartz watch)
  • Replacing the bracelet (no soldering involved)

Additional services

In addition to the planned service, the watchmaker can propose:

A full service involves complete disassembly of the movement. A watch will routinely require a full service every 4 to 5 years, or because of a malfunction. This is a lengthy procedure (at least 4 weeks) given the number of stages involved. For example, controlling the watch's functioning can take 2 weeks. Damaged or worn parts, such as wheels or springs, must be replaced.

A full service includes:

  • Diagnosis
  • Removing the movement from the case and complete disassembly
  • Cleaning the movement
  • Replacing damaged or worn parts, reassembly and lubrication
  • Regulating the watch
  • Refitting the movement in the case
  • Replacing the battery (for quartz watches)
  • Replacing the gaskets and testing water-resistance
  • Testing the watch’s autonomy
  • Cleaning the case and bracelet
  • Polishing and inspection of the watch’s exterior

Restoration is for valuable watches, typically over 20 years old. It involves restoring the watch to working order, if necessary by manufacturing replacement parts for the movement.The leading watch manufacturers can restore their vintage watches.It is almost impossible to predict how long restoration will take: what counts is the quality of the result.
