Deconstruction Grand Seiko

Post by koimaster » June 7th 2020, 5:51pm

The Spring Drive Chronograph combines traditional historical elements from conventional horology such as the pillar wheel with Spring Drive’s electromagnetic time regulating system.
Introduction/functions

The Grand Seiko Black Ceramic SBGC221 is a Spring Drive chronograph with GMT, date, power reserve indication, and automatically wound. The power reserve lasts for 72 hours. Accuracy: ±1 second per day / ±15 seconds per month (average). The Chronograph records up to 12 hours with the minute and hour counters visible on the right hand side of the dial, central chronograph hand. The power reserve is set at 7 o'clock and the constant small seconds at 9 o’clock.

Is there a capacitor that needs to be changed out in 20 years like the kinetic movement?
It doesn't actually store electricity so no obvious need for one. Nevertheless there's been some interesting speculation online if they're incorporated on the IC.

So, I don't actually know but I will in 15 years. Then again the mechanics will need service before then and I'll likely have been set on fire and consigned to an urn at some local wat by that time.

Better than being consigned to WIT, which happened to a guy we knew.
I find tv watches to be like the guys who raise their truck you need a fricken ladder to get in. It’s a attempt to look cool... that’s all.
