In the world of high-end watchmaking, a new king of slimness has been crowned. The Bulgari Octo Finissimo Ultra holds the undisputed record as the world’s thinnest mechanical watch, with a mind-boggling total thickness of just 1.80mm.
To put that into perspective, lay it beside a Swiss franc coin, and the watch is still slimmer. This incredible feat of engineering is what justifies its staggering $400,000 price tag.
