In order for Watch technicians to be able to change the batteries of any watch brand, they will need to go through this four step process:
The first step in battery replacement for watch technicians is that they need to undertake a full inspection of the watch. They need to ensure that all components, including cogs and gaskets, are in working order.
Select the appropriate Battery
Next, Watch technicians need to research the market for the most appropriate battery. These should have been designed for the specifications of the watch. They should also be recommended and used by most watch manufacturers.
Once the battery has been replaced, the back of the watch will require resealing. This ensures it is water resistant. This requires a special water-resistance seal, and will need a second application due to natural removal through aging. This is particularly true if the watch is worn during sport or has been submerged in water during previous use.
Lastly, pressure testing ensures that the water-resistance seal has been applied correctly and keeps water from entering through any gaps. This is usually an additional service and may be charged as such.
Most watch technicians can carry out this service.
