Bulgari has made a habit in recent years of breaking horological records at Baselworld, by introducing the world’s thinnest tourbillon in 2014 and thinnest minute repeater in 2016, for example. e watch-and-jewelry brand shattered another such record this year with the Octo Finissimo Automatic — just 5.15 mm thin, it’s the slimmest self-winding watch on the market. Expect a full review in one of the upcoming issues of Watchtime; until then, here are the most important facts: e Octo’s case is made of titanium, measures 40 mm in diameter and is water resistant to 30 meters. e in-house Caliber BVL 138 Finissimo — 2.23 mm thin — is on display through the sapphire caseback. It has a platinum micro-rotor and beats at a frequency of 21,600 vph; power reserve is 60 hours. e watch comes with either a black alligator leather strap or a titanium link bracelet. Prices are $12,800 on the strap and $13,900 on the bracelet.
