When a heavy load is encountered the watch switches to high power mode to keep it at the correct time, the power used jumps from 0.7 Micro Amps to over 8 Micro Amps, this is about twelve times the normal power.
The problem is that the watch will eventually stay in this high power mode. This is caused by the gas escaping from the Capacitor over the years; this gas cannot escape out of the watch and condensates on the mechanism and contaminates the oils making the movement very stiff. The only solution is to clean the movement thoroughly.
The power device (capacitor) that was used is now obsolete (they start to fail after about 6 years).
Seiko are now supplying an upgrade kit containing a rechargeable Accumulator (Titanium Carbon Lithium Ion), which is much more powerful than the old capacitor that only powered the watch for a matter of days if not worn, even when the watch was new.
This Seiko upgrade kit will provide power for months of inactivity as it is 30 times more powerful and should last at the very least 20 years.
All the Seiko Kinetic watches that we overhaul are soaked for 24 hours to soften the oils prior to being ultrasonically cleaned.
Seiko Kinetic watches can be dated by the first number of the serial number on the rear case at the bottom (i.e. 7xxxxx = 1997 or 2007)
Our charges are less than half the high street as there is no middleman, also you will have your watch back between four and ten times quicker.
