If you’re anything like Cameron Diazyou’ll never forget your first watch. “I was 18, I just learned to dive, and I was going on this two week scuba diving trip, and I had my eye on this black dial, men’s dive watch in stainless steel. I got my money, went and got it, and I wore it forever! I still have it,” Diaz tells InStyle.com exclusively during the grand opening of Tag Heuer‘s New York flagship store. It must have been fate that Diaz’s very first watch was a Tag, given that she is the brand’s celebrity ambassador.

So as Tag’s spokesperson and one of Hollywood’s sexiest ladies, how does wearing a watch make Diaz feel extra sexy? “What I love about Tag is that I have pieces like the Aquaracer, or the Link Lady that are really jewelry for me. When I wear them, I wear them a little loose, more like a bracelet,” Diaz says. “Then I have my Monaco, which is like my big dude man watch. It’s chunky and sexy,” Diaz laughingly admits. “So for me, it’s being feminine, it’s being masculine, it’s playing to all those things all at once or being very specific to one thing just because that’s how I’m feeling,” she explains. “I find it—as anything you wear—being something that expresses how you feel inside, what you’re in that moment, and what you’re feeling about yourself.”

When Diaz isn’t working out alongside her trainer Teddy Bass or filming Annie as Miss Hannigan (which is now in post-production), Diaz likes to dress up her look with a few simple jewelry flourishes. “I love my rings and I do like the combo of my rings and my watch,” she says. “If I do something that’s flashier, it’s usually just one piece.” Which begs the question of whether she follows Coco Chanel’s famed rule of removing at least one accessory before leaving the house. “No, because I don’t feel like I over do it,” Diaz laughs. “But you know, if I was Coco Chanel, I would probably be putting a lot of jewelry on because she had access to Chanel costume jewelry at some point didn’t she, so I would have said the same thing!”
