While phone makers have largely recovered from their obsession with thinness (Vivo’s 4.75mm X5 Max from 2014 still holds the record today) high-end watchmakers still have the bug – and Bulgari’s Octo Finissimo Ultra COSC proves it.

At just 1.7mm thick – that’s about the same as a strand of spaghetti – the Octo Finissimo Ultra shaves 0.05mm off the previous thinnest model. That might not seem like much, but when you’re dealing with such slim margins, a tenth of a millimetre can be record-breakingly significant.
