Hi Ian,
I've noticed Seiko dials are very subtle, and there do seem to be minor differences in the dials from model to model. To my eyes. Other people say they don't see a difference. It might be production variation, or aging of a single watch.
I think the watch you are considering is very close to the one I have, with the enhancements of an updated movement and a see-through case back.
Regarding the strap, yes I have put straps on virtually all my Seikos. Most of my bracelets are in Ziplock sandwich bags, labeled with permanent markers so I don't forget which bracelet fits which watch.
The GS tang buckles are nice, but expensive and hard to find, and the 2-3 deployant I have tried are even more expensive and are uncomfortable, so I don't use them.
Hope this helps.
Cheers,
Mike This message has been edited by cazalea on 2014-06-19 01:10:14
