That said, John Harrison didn't have access to Solidworks and 6-axis CNC machines like today's high horology brands do. The final product may still be fully mechanical but the process of getting there has advanced a bit.
They also didn't have the materials we use for springs, or some of the mechanisms we use. The fact that these devices are the same basic tech from the 1700s, while at the same time being much more advanced, is actually part of the appeal for me.
