Grand Seiko 9SA5 movement - very interesting indeed...

A short video, for those who appreciate the technical side of things .

I respect Seiko and had always wished that the Japanese giant would make use a full balance bridge, and more so a Free Sprung Balance on it's high end movements.

I always thought the 8L35 movement should have these features, like the venerable 3135.

I was even ridiculed at times, for commenting and not being a watchmaker, but I do know a thing or two about basic Mechanical Engineering.

Apart from upgrading to a full balance bridge and free sprung balance, now it seems that Seiko took a page out of Omega's (George Daniel's) book with their new 9SA5 movement. The new escapement (1:10 in the video) bears an uncanny resemblance to Omega's long established Co-axial escapement. Very interesting indeed to see such progress in what essential is what is essentially ancient technology.

Enjoy :) - https://www.youtube.com/watch?v=BUbJvRFHqoQ&t=451s
