Here’s a dual purpose timepiece with absolutely no moving parts. The unique way this Jonco watch keeps time is important, but more importantly, the watch could save your life if you are attacked by ninjas or vampires.
On the face of the watch is a spike; when attacked, aim the spike for the eye of the attacker, then run like heck. To tell time, buy a beer, spike the receipt on the watch and check timestamp on receipt. Drink and repeat until time doesn’t matter.
