If your Kinetic watch is moving two seconds at a time, this is the indicator that the capacitor or battery is discharged; it requires wearing more often or requires a service. It is no use just shaking it.
If your watch stops or loses time overnight and you have been wearing in the day, then it requires a service.
Seiko recommend having your watch serviced between two and five years, but in our experience ten years is about right for electronic watches.
Kinetic watches MUST be cleaned, due to the gas escaping out of the obsolete Capacitor over the years; this gas is trapped in the watch and will have contaminated the oils making the movement very stiff. It then uses 12 times the normal power trying to keep going; therefore your arm movement is not enough to keep it charged. Therefore it is no use just replacing the capacitor as the new Cell will only last a few weeks.
The replacement Cell for the Capacitor (Titanium Carbon Lithium Ion) does not gas off, so this will not happen in the future once the movement has been cleaned; also it is 30 times more powerful and should last at least 20 years.
We do not charge any extra for new parts fitted in your Seiko (unless damaged by someone), as only about 1 in 15 require parts so it is swings and roundabouts and keeps it simple.
There are many people saying they will service your Kinetic for about £40, but they don't clean the movement, they only replace the capacitor, clean the case and they don't give a guarantee.
