Spring Drive - by far and away the best, in-depth explanation I've ever seen

I always tell my wife how amazing GS's spring drive technology is - how they use quartz technology to create this quartz-mechanical hybrid that gives you the best of both worlds.  Well, today, she surprised me.  Her eyes didn't glaze over, and she actually asked me, "Oh, how did they do that?"

And my response was, "Well, they have this main spring, just like in any mechanical watch, and then...  a quartz crystal...  something, something...  tri-synchro regulator...  uh...  it just, you know, works."  When she started laughing at me, I then pointed out to her how cool the sweeping seconds hand looks, and well that's all you need to know.

Well, friends, to save you from the same embarrassment, I bring to you this incredible find from the Crown & Caliber YT channel - finally, you will be able to understand and explain to your spouse, who couldn't care less, how spring drive actually works:

(@MarkHackman, I know that your video series is focused on "Hidden Gems," and I absolutely love them, but can you tell Luca that his videos are absolutely hilarious?  The 80's style, corporate-training VHS aesthetic is brilliant.)

P.S., totally unrelated, but I'm just gonna leave this here as a shameless plug to y'all to consider bidding on this watch in order to help alleviate extreme poverty in Africa - get a watch, help someone in need, get your donation doubled with matching funds:

yea, done pretty well.

A few comments:

Not all quartz crystals oscillate perfectly. Seiko grows their own quartz, and measures them for accuracy, only the best of the best of the best get sent to Grand Seiko. This is why a spring drive is more accurate then pretty much any non Grand Seiko watch (not including those that update from outside signals), and a Grand Seiko quartz is even more accurate then the spring drive,

I like how he explains it, but how I like to describe it, for those that don't like the idea of electronics within the watch, like it's a quartz watch or something, is this:

Every mechanical watch is mechanically driven and electronically regulated. If you have a mechanical watch, once every few weeks or so, you will check the time on your computer or phone (or a quartz watch), and set it. This means it's electronically regulated, however only regulated once every 3 weeks, and requires a human to be in the middle. What Grand Seiko did, is just put that computer you were going to use anyway, into the watch, and then is regulating the mechanical movement 8 times a second for you.

If that does not impress you, I don't know what will :)

Thanks for sharing, and thanks to @Jeremy for his take.

Amazing take!  💯

It's funny how there seems to be 2 tribes on spring drive.  One tribe is entirely against, because it corrupts the purity of the mechanics inside the case.  The other tribe just loves the cutting-edge  tech.  

Actually...  now that I think about it, there's probably a 3rd tribe.  3rd tribe couldn't care less about any of that, and they just like the smooth sweep of the seconds hand (probably me):

"Ooooooh...  pretty..."

I ended up watching the entire playlist. The chronograph video in the series was really interesting. It also cleared up the mystery of the different date change mechanisms.

Wow!  I thought I had a lot of time on my hands!  But, you are the master.  Teach me your ways, dude!

I'm a huge fan of both the Spring Drive and the 9F quartz movement. Quality stuff is quality stuff.

This was a great find, and great video. We owe ya one, Omeganut. 💯

Crown and Caliber produce some amazing stuff. I can’t believe they don’t get more views!

I guess they don't howl in front of refrigerators in their basements enough. 😉
