Los relojes Seiko están diseñados para proporcionar un servicio preciso y fiable durante un largo período. 
Sin embargo, como cualquier instrumento de precisión sensible, un reloj necesita servicio periódico para garantizar su perfecto funcionamiento. La frecuencia de dicho trabajo depende del clima y del cuidado individual del reloj por parte del propietario, pero en general, recomendamos que revisen su reloj cada tres años en un Centro de servicio autorizado Seiko.

In order to prevent watch parts from wearing out, a watch movement needs lubrication.
However, lubricant oil deteriorates after years of use and this may cause a watch to lose time or stop.
During disassembling and cleaning, our watchmakers will inspect the watch condition and dirt and moisture that may cause malfunction will be removed and worn out parts and gaskets will be replaced with genuine SEIKO parts, the disassembled parts will be lubricated again, and waterproof performance will be checked.
Periodic servicing is also important for ensuring the water resistance of the watch. Water resistance of the watch is not permanently guaranteed. It is affected by the ageing of gaskets or deformation of watch parts due to an accidental shock.
We recommend that you have them replaced when you replace the battery.
