Natalie Portman wears a Jaeger-LeCoultre Reverso

Charlotte Purdue is the respectable half of her family, a curator at the National Portrait Gallery while her brother Luke is off stealing art. When Luke pulls her into the hunt for the fountain, Natalie Portman plays her with a rose gold Jaeger-LeCoultre Reverso Classic Duetto on a bracelet, the two-dial version of the Reverso, and the costume logic started simply: on a woman with that job, it looks the part.

Costume designer LouLou Bontemps framed the watch as inheritance rather than shopping. A piece like this gets passed down, she reasoned, the way a Patek does: investment pieces, handed through the family. The same thinking gave her brother a single rose gold Master Control read as their late father's watch, all he consistently wears, while the billionaire funding the expedition got a two-faced Reverso tourbillon chosen to mirror his double life.
