I rarely wear a wristwatch or finger ring for all the reasons Stan mentioned, in addition to frequently working around high voltage equipment. NCTarheel's wood lathe accident is a kind of close call I could live without. I do have several vintage gold pocket watches, and always carry one while hunting. I know I could just use my cell phone, but when I'm hunting, my cell phone is muted, and I try to forget I have it. However, there was at least one time I bid and won a Gunbroker auction while in the woods deer hunting, so technology isn't all bad. My vintage pocket watches make as much sense as my vintage double shotguns or flintlock rifles. I like them, so that's all that matters.
My grandad was given a wedding band by his three grown children when he was about 60 yr's old. He had never had one. He put it on and wore it until he was standing on the narrow ledge on the outside of a stake body farm truck, holding onto the top edge of the boards. His foot slipped and he fell straight down. Along the way his ring caught on some exposed threads of a 3/8" bolt. It nearly pulled his finger off. It didn't but it ripped the tissue from the bone so badly that the Doc had to saw the ring off before patching him up.
Lesson learned, for him and for me.
Years ago, I worked with a girl who lost most of her left little finger when her pinky ring got caught on a wrought iron stair railing. She told us how painful and ugly it was with tendons pulled out and the broken, severed, bleeding joint exposed. And she also had phantom pains in the missing finger as a reminder too.. Yet she continued to wear a pinky ring on her other hand. Now that is almost as dumb as a gun owner who votes Democrat.
