Seiko Kinetic watches are designed with a very special circuit that compensates for heavy loads, such as when the Day/Date is changing at midnight or if the watch is knocked as the seconds hand is moving.
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 and 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.
So it is no use just changing the cell without cleaning the movement as it is just a waste of money, it will not hold a charge for more than a few weeks.
Now press the power indicator button, if the second hand moves more than 5 seconds the capacitor has lost all its capacitance. (If the capacitor was in reasonable condition it would take about 500 shakes to get more than a 5 second movement.)
All the Seiko Kinetic watches that we service are soaked for 12 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 much less than the high street as there is no middleman. Also you will have your watch back between four and ten times quicker.
