Horology 101 - mainspring barrels
Mainsprings were originally just connected to the inner barrel wall on one end and to a center post on the other. This created a few problems. Since the barrel was rotating one way while the watch was ticking, but in the opposite direction while it was being wound, the watch lost time during winding. Also, if the mainspring broke it caused a violent snap and a surge in the opposite direction which would break other parts like jewels and gear teeth. Lastly, the watch was not isochronistic since a fully wound mainspring pushes the gears with much more force than a nearly exhausted spring. The first solution was to add a fusee between the barrel and the gears.

5205g dial options
I once heard that light color dials seem to wear slightly larger than darker ones. Not sure I'm fully convinced by this statement, but I wonder what your views are.

Thanks
