Cleaning

The case and bracelet must be cleaned to eliminate dirt and perspiration.

 

Cleaning the case

 

• Water-resistant watch: after checking that all parts are screwed tight, gently rub the watch with an old toothbrush and soap. A household creme cleanser can be used if the watch is very dirty. Rinse with clear water and dry using a soft cloth. 
• Non water-resistant watch: first remove the strap or bracelet then clean the case with a moist cloth. Rub gently in the corners with a soft brush then wipe again with a moist cloth to remove any last traces of dirt. Wipe clean and dry with a soft cloth. You can also clean the case “dry” using a gentle laundry stain remover on a cotton bud.

Cleaning the bracelet or strap 

• Metal or rubber: clean using the same method as for a water-resistant watch.
• Leather: rinse the strap under clear water then rub it with a soft brush and a little soap. Wipe with a soft cloth and leave to dry in the open air, away from any source of heat.

   

 

Servicing

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 diagnosis of the watch’s parts or exterior
• Replacing the battery (on a quartz watch)
• Regulating the watch
• Replacing the gaskets and checking water-resistance
• Cleaning the case and bracelet 

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.
