Now that I'm retired, I no longer wear a watch.......I do still have a calandar.....somewhere.

Maybe this is it.
I ask questions and people tell me things too though and about batteries going out at the same or around the same time, I get that often. "For years they all work and now they're all dead?" They could be wrong though. It's too odd.
People 80 or so say their watch only lasts a year or Less? Either the watch is dirty or they're draining the battery on their own somehow.
Someone explain the "on their own somehow" because I am wondering about that. Energy draw? Just a thought.
Batteries do not stop draining with the stem pulled btw. They do draw slower but they still die. I always tell people the money saved on a battery pulling the stem is spent on wear and tear setting those fragile wheels the correct time. Set and forget I always say.
Mechanical movements are designed to be set often.
Right now I wear a eta6497 inside a new 47mm watch case. I gave my dad some old pocket watches which he loves (he's a watchmaker) and he gave me this back with one of the pocket watch movements inside. It's from the fifties and still kickin it. I wind it once a day. Old school. Matches the big look everyone is doing these days but my watch is actually filled with watch. Cool
