Thanks Ken for posting this for us!
I have a 12 or 13 year old Seiko Kinetic Auto Relay and that was my watch during college.
(Some of my college mates say it gave me mystical powers as I started as a silly kid but ended up as the valedictorian of the cohort...)
I am glad that Kinetic is still one of the key technologies of Seiko.
For the record my watch has not been serviced once since I bought it and it is keeping excellent time still.
I also wear it for swimming often.
All these Seiko posts are inspiring me to wear my Seiko again and do a post here!
I am also fascinated to learn more about the GS line - they are so rare in Singapore!
Cheers
Robin
