Caliber 0100
The second hand of a watch counts out
31,536,000 seconds every year.
A watch with accuracy of ±1 second per year
must mark those millions of seconds with annual
deviation within just one second.
To mark the seconds with such perfect purity,
all the watch’s individual components
need to be made with greater precision.
