tough and precise and beautifully finished. The Spring Drive has some advantages as you so well explained.
You show your here in a great "spring" shot (no pun intended, I´m just refer to the Season it seems having been shot)
I don´t own a SLGA0211 in my collection but have a SBGA211 Snow Flake which also has a Spring Drive movement inside, which could serve me too as a perfect Zombie invation watch.
Best cordial regards, Abel
