I have a bit of an obsession with mechanical type stuff. Gears, springs, etc. Watches fit that niche extremely well, as well as being useful. All of mine are mechanical self-winding watches, though my GF has a solar powered seiko that is supposed to run for pretty much eternity without any issues, so long as it gets 10 minutes or so of sun per year, which is incredible. What watches do yall wear in the bush? My Citizen Ny0040 at the beach yesterday!
