Just as with any other precision instrument, a watch needs to be maintained regularly to ensure faultless performance. We are not able to specify a frequency for such operations, as this depends entirely on the model, the climate and the care with which each watch is looked after. Generally speaking, a watch should be serviced every 4-5 years, depending on the conditions under which it is worn.
WHOM SHOULD I CONTACT FOR MAINTENANCE SERVICES OR BATTERY REPLACEMENT?
We recommend that you contact an approved Longines service centre. It alone will have the tooling and equipment required to carry out this work and perform the necessary checks to a professional standard.
