Manual-winding Mechanical Hi-Beat 36000 80 Hours Caliber 9SA4 

*beautiful, i expect some thin watches*

This is a great achievement for Grand Seiko as the most elegant handwound pieces always lacked a bit of refinement due to their case thickness. The new 9SA4 will be a game changer for future Seiko dress watch releases! The watch showcased in that video, the SLGW003G, is only 10.0mm thick!

Remarkable. I really like the reserve indicator being in the back side.

Incredible movement

The bird singing makes me comfortable and chill

このコハゼ、なかなかの力作ですね。巻き上げる時の感触と音にこだわった成果でしょうね。ここだけで設計者に感謝したい位。懐中時計の頃に似たような構造の物が有ったような気もする。セキレイがモチーフらしいが、巻き上げる時の動きが鳥のついばみに本当に似ている。

I hope that in the future Grand Seiko will produce a movement that supports the outsized big date feature, both calibers 9s 9f 9r, but it seems that for the time being the calibers that are going up are 9r and 9s, especially from the development of the base caliber 9sa5, I also like the power reserve indicator feature ,,, good job for grand Seiko

おめでとうグランドセイコー

Does the new Grand Seiko calibre 9SA4 movement have hacking seconds?
