I’ve linked to the wonderful work of Bartosz Ciechanowski before, his delightful explainer about how cameras and lenses work. I love the physicality of Ciechanowki’s work, the way the widgets demand to be played with and spun around, and also the way the fully complement the subject.

He’s published a new one and it’s a doozy, all about mechanical watches. I’ll admit I’ve spent over an hour with this already and I’m not yet fully through it, though I certainly have a much better understanding about how the watch I wear nearly every day works.

The next explainer I’d love to see from Ciechanowski is how he builds these explainers.

For more mechanical watch nerdery, I highly recommend the Wristwatch Revival YouTube channel — it’s one of my favorite bits of ASMR
