Mechanical watch is a mesmerizing device. Makes you wonder though, why there was so little progress around mechanical technology (not only watch specific) lately? My car can talk to me, steer, retain speed by following other vehicles, but the most amazing mechanical innovation it has is a frustratingly slow, whining seat memory function. It’s not only boring, it also relies on a century old tech. Watch are the same, auto wound mechanism was introduced 98 years ago, was slightly improved 60 years ago, still is expensive to produce and maintain, still has reliability issues. |

Engines are roughly 2X better now in the categories that matter: power output, fuel efficiency, and expected lifetime. Some of the fuel efficiency gains have of course been canceled out by increased overall vehicle weight, so it's easy to overlook how much more efficient the engines themselves are.
In 1986, a Ford Mustang GT had a 5.0L V8 that produced 200HP.
In 2021, a Ford Mustang GT has a 5.0L V8 that produces 460HP.
A 2021 base model Ford Mustang has an engine that produces 310HP from only 2.3L of displacement.
(Not that Ford is special in this regard; I just picked the Mustang because they've produced a 5.0L V8 for most of the brand's lifetime and it's fun to compare a 1986 5.0L engine versus a 2021 5.0L engine...)
