Bulgari unveiled the Octo Finissimo Automatic, the brand’s latest work of wrist sculpture, which sets a record for the thinnest self-winding mechanical watch at the recent Baselworld watch fair in Switzerland.

Photographed by Ellen von Unwerth on Spanish model Jon Kortajarena who is brand ambassador for Bulgari, is the Bulgari Octo Finissimo Automatic at a mere 5.15 millimeters thick with the the movement itself at 2.23 millimeters.

In 2014, the company released the Octo Finissimo Tourbillon, billed as the thinnest tourbillon watch ever with a movement that is 1.95 millimeters (a tourbillon, a prized watch complication, is a tiny rotating cage that helps fight the effects of gravity on a mechanical watch movement). Last year, Bulgari followed up with the Octo Finissimo Minute Repeater, with a movement that measured a record 3.12 millimeters.

Both of those were manual-winding watches; the Automatic is self-winding.
