Dressed head-to-toe in Louis Vuitton, Millie Bobby Brown was styled well beyond her 15-years at this year's SAG Awards, but it was her watch that caught our attention.

Taking to the red carpet on Sunday night, the Stranger Things star donned an Audemars Piguet Royal Oak timepiece. She went for a traditionally "masculine" shape, opting for the 37mm automatic Royal Oak with a silvered dial and a diamond-set bezel.

The Royal Oak is most recognizable for its octagonal bezel shape, which is attached with eight hexagonal screws, creating a geometric look. The watch also includes a “tapisserie” dial and an integrated bracelet — features that made waves when it was first released in 1972.

Speaking about her red (or in this case, gray) carpet fit, she said, "I definitely wanted to go for more of a masculine, but very feminine look and [Louis Vuitton] got it just right, as usual." Watch below.

Brown told People TV that she and her cast-mates are ready to get back to shooting the fourth season of Stranger Things. Filming is slated to begin in January and run through until August.
