great views
I had a slight oops on my bike while wearing my BigBlock.
it stopped working.
it needed a new quartz from another Hughes and it's ticking again.
as for digital watches - in most cases shockproof is the word used for the durability of the quartz. heavy-duty watches have robust cases and more expensive quartz crystals with a better "suspension".
in mechanicals we have the famous "inca-block" suspension system for the balance wheel introduced in the 30's and later renamed to shock-proof
