Grand Seiko's Mechanical Technology - 9S6X/9S66 in the SBGM031/21/23
In considering a recent purchase, I scoured the internet for any technical information pertaining to Grand Seiko's lates 9S6X series calibers. This is what I summarized. I really hope Seiko makes all this information much easier to find some day! Grand Se...
I'm almost tempted to mail you my watch
so you can tear it apart and critique it :) What do you think about the MEMS vs Silicon escapement? I always thought the main benefit to silicon was its ultra precise manufacturing and antimagnetic properties, but then again if we're sometime in the futur...
The reason Seiko did not adopt silicon
is that under certain conditions it is fragile and more prone to cracks or fracturing than metal parts. This is according to the engineers at Seiko Shizukuishi Watch Studio. - SJX
Good point, I think Seiko's philosophy
is to maximize the potential of all conventional technologies.
I didn't know that Si had weaknesses too
but then which company who's currently or planning to use it will admit any weaknesses to the wonder material right? Thanks for the insight SJX!
I still haven't taken mine apart yet so...
And it's certainly long over due (I got it in 2003). A watchmaker friend of mine frowns at me whenever he sees me wearing it, but hey, if it ain't broke... I am ill-equipped to speak intelligently about MEMS or silicon components in watches. Smarter minds...
I'm a little reluctant to write it yet
due to some minor conflict of interest. But I'll try to stay neutral. There are a few small complaints that I have about the strap and clasp but I have sensitive wrists.
great review Ed. its always good to know about the parts no one sees.
i like Grand Seiko's and did have several vintage and one new one, but for some reason i let them go. cant think why. i'm now searching for a good 1964 35 jewel handwind, but they are all out of my price range for now. thanks again Ed. best Graham.
