​There are some hairline marks (swirling) on the bezel and all over the entire case, as you would expect, and is commensurate with light occasional use.

Capacitor fitted 18/08/2019 which works perfectly and holds maximum charge. Watch will be kept charging until sale is made.

Sadly we do not currently have the ability to pressure test the watches so can offer no guarantee of water resistance. A local watch shop should be able to offer this service fairly cheaply. 

Customer satisfaction is our goal so please feel free to contact us with any questions you may have or to contact us after purchase if there is anything we can do.

Seiko Kinetic Explained!

Like mechanical and quartz, Kinetic is a platform. Over the past 20 years, SEIKO has created on this platform a suite of Kinetic movements, each bringing unique features to the consumer.

It was at the 1986 Basel Fair that SEIKO unveiled its first Kinetic prototype. Introduced under the trial name of 'AGM', it was the first watch in the world to convert kinetic movement into electrical energy. It was the first step in a development that, 20 years later, has made Kinetic synonymous with environmental friendliness, high performance and long-lasting convenience to a generation of users worldwide. From the launch in 1988 of the first commercially available watch (then under the new name AGS) until today, over eight million Kinetic watches have been sold (as of 2007).
