First off, these are updates to the uber-popular GA-2100s that were link released back in 2019. link The new versions get handy new G-Shock features such as the Tough Solar link charging system (yay for less battery waste!) and Bluetooth connectivity, but other than that they look almost the same.

But on the other side of the question trying to set records is interesting. After all people do lots of things not because they are practical but simply because the challenge link is engrossing. And while "record" in watchmaking is always subject link to caveats sometimes a lot of caveats it's still fun that watchmakers try to set them. Maybe I won't ever buy a watch with an escapement that beats at 108000 link vph but I'll be there in the bleachers cheering you on.
