After two weeks, she was always in the right moment - it is stunning for a mechanical watch. Seiko confidence in the reliability of its watches is such that we can not even manually wind the movement: the watch recharges by movement, who run a disk, which itself dates back a spring or sth like that. On top of that means very light and very fast tic tac small when glue ear; unlike a Quartz that would move the hands in spurts, it diffuses the energy much more slowly, giving the impression that the second hand does not stop. It is still more, really beautiful and I suggest you do a little research on the Internet images to see the back of the watch - it is transparent you will see the discs engrainer.
It is slightly small for today's standards (37 mm), which suited me very well since I have small wrists and I was not used to wearing watches. I really advise to those interested a little to them and want their first mechanical automatic. The case is slightly high (13 mm), so it seems to have a small box of autonomous mechanisms that measure time, and it's really a pleasant feeling.
