The case is very well finished with a combination of matte and bright surfaces. A sapphire exposition crystal is integrated into the rear screw-down bezel.

The dial is elegant and easy to read, even the date is nicely legible. I'm very fond of the power indication, especially on the bracelet model.

Opening and closing the bracelet is a snap, pun intended. Both ends of the bracelet open independently and close to make an almost seamless fusion.  But I'm not pleased with the friction pins used for bracelet adjustment; screw type pins would be a much better (and easier) solution.

In Conclusion

The Seiko Spring Drive is a revolutionary watch. Without doubt other watch companies will study it and eventually the technology will be copied. Very impressive to say the least.
