For one film star, the answer to what goes with blue and red was Bulgari. Naomi Watts walked the red carpet at January’s Screen Actors Guild Awards event in a blue Burberry gown accessorized with a Bulgari Lucea watch—as well as a ring and earrings of platinum, blue sapphire and diamonds by the Italian maison.So what made the looks of Nicole Kidman and Eddie Redmayne tick at the Los Angeles event? A vintage Omega Secret watch in platinum for her and an Omega Globemaster for him. Kidman, whose thriller Secret in Their Eyes landed in November, perhaps finds her undercover 1952 watch useful in situations when discretion is required. The watch’s bracelet, though, has hundreds of diamonds, in all sorts of jeweler’s cuts, in plain view. Not to blow her cover: She’s worn Omega Secret watches before. She donned a piece from 1955 at the Cannes Film Festival in 2014.
