Tanner Goods makes indestructible belts in a lot of different widths to suit your use case (thinner for dressier/more formal stuff, wider for more casual)

Guarded Goods also makes bulletproof leather belts, also with dressier options, as well as a variety of custom/made-to-order options (he stocks a lot of leather). I remember this guy posting his very first wallets on a sub about 8-10 years ago and he grew his business into his full time gig. That's dope

I wore a similarly constructed veg tan leather belt from Corter for 5 or 6 years before I gained too much weight. Other than the patina and the belt forming to my waistline, there's effectively no wear on it and I still have it in a bag or drawer somewhere. I linked the shop page, but they've not made belts for a while.

I recently bought a belt from Ewing Dry Goods that I've been wearing with a recent denim purchase. These are handstitched vs. riveted, so I guess you could maybe possibly not have it FOR LIFE (I'd argue it could be restitched easily). But the stamp is cool and it's a one man operation - love supporting stuff like that.

Also have to mention Hollows Leather because I have always wanted something from him but not had the need at the right times to pick something up
