My parents bought an automatic Orient watch for each of them in the 70s - those that don't require batteries nor anything. My mother's watch was stolen somewhere in the 2010s and my father broke the crystal and kept stored for like 15 years or so. Just some weeks ago I remembered about it and sent it to service - now it looks and works like new and the service itself wasn't expensive. I'm pretty amazed.

Super

I started working for a clock and watch repair shop a few months ago after deciding it has better job security than computer programming :) I change batteries, replace crystals and hands etc

I thought I would like the mechanical puzzles (not all that different than debugging programs) but now my favorite part is just knowing I’m keeping a talisman going, for someone to pass on to their grandkids, and it’s true that the well-made stuff can last centuries with occasional service.
