Excluding things like your body!
It's an incredible piece of Swiss engineering and such a stark contrast to the world of disposable personal electronics I'm used to. Best $800 I ever spent on a machine.
My partner came with a snow shovel that belonged to her grandparents. It's probably my favorite they-don't-build-'em-like-that-anymore object. I'm guessing it's mid last century, '40s, '50s. It's still solid af and easily better than anything I could get at Home Depot nowadays.
I also have plans to purchase some old landline phones to create a room-to-room phone system with a cheap PBX machine, but that's a long term plan.
I have a few fishing rods / reels that date back to the early 90's that are still in my pile that I carry around when I go fishing; although of the two rods I use most often, none are the really old ones.
I have at least one toolbox and a few small hand tools (ratchets, wrenches, sockets, etc) that also date back to the early 90's. Most of that stuff is Craftsman brand.
My coffee pot (a Mr. Coffee brand drip machine) is from about 2004 or 2005.
Nothing else really jump to mind.
It’s honestly amazing. It’s the most longevity I’ve ever gotten from an electronics purchase.
Second oldest thing i own is a steamer for kirgizian dumplings (manty), with the price - 2 kopejk - embossed into on of the handles. Must be from the 70-80's.
And a few other old things, but none of them being older then me, except these two things :) love them and I hope, my kids will love them, too, soma day - if i find a wive whos is not pushed away by these things ahah
After that I have a safe from 1925, so 100 years old this year.
