Seikos are usually tough watches as well !
I have the Kinetic Sports 100, which is my second Seiko Sports 100 since the last one got stolen. I don't like battery watches, I do like automatics, so the kinetic is somewhere in between, currently, it has lasted eight years and is covered with dings and scratches, even the mineral glass on the front has a chip taken out of it.
I've been a fan of Seikos for some time - like their rough and ready, yet decently constructed 7S26 movement, and as for Kinetics, I have several, I've even got the induction charger for them.
What I would say, is the Kinetic movement is interesting, appeals to the geek in me, but truly is a solution looking for a problem.
In all the Kinetics bar the latest I've got, I've had to replace the capacitor (Seiko supply an upgraded part, which is really a Li-ion rechargable cell).
The idea of it, I guess from inception, had the downsides of a mechanical auto, with the flakeyness of some early component choices (ie the capacitors) which left you with a watch that didn't deliver on the "never needs a new battery" idea and also has the mechanical maintenance overheads of traditional mechanical automatics - perhaps more.
I've got one with a stuck generator mechanism - not sure if it would be easier to service a 7S26 mechanical auto.
All that said, though, I still think Kinetics are cool - they just don't make any real kind of sense.
And Seiko make some fine watch movements - and in some examples, some very fine watch movements.
Kinetics are noisy though,or is that the automatic function, that big weight that slings around under it's axis ?
