Billie Eilish’s watch collection is as nonconformist as you’d expect: the Grammy-winning singer wears everything from Casios and US$6 China-made watches to pieces by Rolex and Audemars Piguet

Billie Eilish is the poster child of Gen Z, with a style that defies convention and won’t be put into a single box. At 23, the trailblazing singer has built a career on challenging norms and shattering expectations, from her ever-evolving hair colours to her genre-defying music and gender-fluid fashion choices. Since she exploded onto the scene at 17 with a debut album that took the world by storm, she’s been redefining the rules.
