Plus, you have an electronics device that can fail or be covertly fried or a frequency wave that can be jammed. When your life depends on it, keep it simple and mechanical and stay away from electronics.
If it’s “smart”, it wouldn’t take much more to enable it to: record where and when you shoot it (or even handle it); record the direction it was pointed when fired; record the calibre of the ammo you used; and, to transmit reports to the “authorities”.
I’m a watchmaker. Today, among others I finished the repair of 2 watches. One is a Waltham pocket watch made in 1873, and it now and STILL running like it was a month and a half old. At its current rate of wear, I estimate it will last more or less another hundred years.
The other was a very high grade Swiss made BATTERY powered quartz day/date man’s watch. It was purchased and given as a Christmas gift in 2013!!! Tuesday it stopped and was brought to me. Gee—something in the circuit died and the watch stopped. This high quality movement is seen so often I keep a couple of circuits in stock, just to save ordering time. Any electronic circuit can and will eventually fail. The company will, of course, back up its warranty. Not a big deal.. HOWEVER—
Question....You want to have you very life dependent on that somewhat fragile thing on your wrist?
