The word "opus" is often defined as "a work of art that's usually on a grand scale". And that's precisely how the Harry Winston Opus XIII Watch presents itself. Drawing from the work of the late, great Harry Winston (one of the world's most famous jewelers), the Opus XIII exudes with a profusion of flair and magnificence. The timepiece's remarkable bezel is constructed with 18k white gold while the dial that it houses is faceted with a stunning sapphire crystal dome. The Opus XIII also employs a non-conventional manner of telling time as the watch features fifty-nine pivoting minute hands, eleven rotating triangles to denote the hours, and a unique sliding trapdoor that you'll want to see for yourself.
