Movies usually use clothes to tell you who a character is before they even open their mouth. In the 2014 hit The Other Woman, the costume design wasn't just about looking "rich" or "New York chic." It was a surgical strike. While Leslie Mann’s character Kate King was all bright sundresses and suburban floral prints, Cameron Diaz’s Carly Whitten was the embodiment of high-powered, cold-edged legal success. And right there, sitting on her wrist in almost every scene, was the ultimate power move: the other woman watch.
It was a Cartier. Specifically, the Cartier Tank Française.
You’ve seen it. Even if you don't care about horology, you recognize that rectangular face and the integrated metal bracelet. It’s a piece of jewelry that happens to tell time. For Carly, the high-flying attorney, it wasn't a fashion choice; it was a uniform requirement. It signaled she had her life together, even while she was unknowingly dating a married man played by Nikolaj Coster-Waldau.
People are still searching for this. A decade later. Why? Because the "Other Woman watch" represents a specific era of "Boss Girl" aesthetics that felt attainable yet aspirational. It wasn't a diamond-encrusted gimmick. It was a Tank. It was timeless.
The Watch That Defined Carly Whitten’s Power
Patricia Field, the legendary costume designer behind Sex and the City, handled the styling for The Other Woman. She knew exactly what she was doing. When you're styling a character like Carly, who is a shark in the courtroom but has a secret soft spot, the accessories have to be rigid.
The Cartier Tank Française she wears—likely the medium or large model in stainless steel—serves as an anchor. Think about the scene where she discovers Mark is married. She’s wearing structured neutrals. The watch is glinting. It’s a sharp contrast to the chaos of the discovery. It's a "clean girl" aesthetic before that was even a TikTok trend.
Honestly, the Tank is the perfect choice for a character who values logic. Invented in 1917 and inspired by the literal tanks on the Western Front of WWI, the watch has always been about geometry and strength. By putting it on Cameron Diaz, the filmmakers tapped into a century of prestige.
Why the Cartier Tank Française?
Most people think of watches as just tools. But in the context of the other woman watch, it’s a symbol of independence. Carly didn't wait for a man to buy her that watch. You can tell. It fits her too perfectly. It’s part of her armor.
- The Design: It features those signature Roman numerals and the blue sword-shaped hands.
- The Bracelet: Unlike the leather-strapped Tank Louis, the Française has a chain-link bracelet that feels like a piece of structural engineering.
- The Vibe: It says, "I have a 9:00 AM meeting and I will win."
There is a specific weight to a Cartier. It isn't flimsy. When Diaz gestures wildly in the film—which she does a lot because she’s a physical comedienne—the watch stays put. It’s heavy. It’s real.

Spotting the Details: Is it Steel or Gold?
There has been a lot of debate on watch forums about the exact reference number of the other woman watch. If you look closely at the high-definition stills from the beach scenes or the office sequences, it appears to be the all-steel version.
Some fans argued it was the two-tone (gold and steel) model, but under the harsh New York filming lights, that cool, monochromatic silver sheen is unmistakable. It matches her silver rings and her neutral palette. Gold would have been too "Old Money" for Carly. Steel is "New Money" and hard work. It’s aggressive.
Actually, the choice of steel is quite telling. In the world of luxury watches, steel is often more desirable for daily wear than gold. It doesn't scratch as easily. It doesn't scream for attention, but it commands it. That is the essence of the character.
The Cultural Ripple Effect of Movie Watches
Movies have this weird power over the luxury market. When a film like The Other Woman goes into heavy rotation on streaming platforms, sales for the featured items spike. It’s the "Bond Effect" but for women’s fashion.
We saw it with the gold Rolex Day-Date in Glengarry Glen Ross. We saw it with the Hamilton in Interstellar. With the other woman watch, it was about capturing a specific type of femininity that wasn't about being a "wife" or a "mother" (roles Kate King occupied). It was about being the woman who owns the room.
Fashion historians often point to this film as a turning point where "professional" style shifted from boring suits to high-fashion integration. The Cartier was the centerpiece of that transition.
The Real-World Cost of the Look
If you wanted to go out and buy the other woman watch today, you’d be looking at a few different paths. Cartier actually updated the Tank Française recently, making the integration of the bracelet and the case even smoother.
- Brand New: A new small or medium steel Tank Française will set you back anywhere from $3,700 to $4,500 depending on the tax and the specific size.
- Pre-Owned: This is where most people go. You can find the 2014-era models on sites like Chrono24 or The RealReal for roughly $2,200 to $3,000.
- The "Lookalikes": Brands like Seiko and Longines have rectangular watches (like the Seiko SUP250), but they don't have that "Other Woman" weight.
It’s an investment. But that’s the point. The movie wasn't selling a fleeting trend; it was showcasing a legacy piece.

How the Watch Complements the Narrative
There’s a hilarious irony in the film. Carly wears this symbol of timelessness and reliability while dating a guy who is the literal definition of unreliable. The other woman watch is the only thing in her life that actually does what it’s supposed to do.
When Carly, Kate, and Amber (Kate Upton) team up, their styles begin to bleed into one another. But Carly stays pretty consistent with her accessories. She is the strategist. The watch is her stopwatch for the revenge plot.
Think about the "laxative scene." Carly is checking her watch. She’s timing the effects. It’s a brilliant bit of prop usage. The watch isn't just sitting there looking pretty; it’s a tool for the scheme. It’s the "Other Woman" taking control of the clock.
The "Other Woman" Aesthetic in 2026
Fast forward to today. The "Other Woman watch" hasn't aged a day. That’s the magic of Cartier. You could walk into a boardroom in 2026 wearing the exact same setup Cameron Diaz wore in 2014 and you’d still look like the most sophisticated person there.
We are seeing a massive resurgence in "small watches." For a few years, everyone wanted giant, 40mm "boyfriend" watches. Now? People want the 25mm elegance of the Tank. They want the Carly Whitten look.
The trend is moving away from tech-heavy smartwatches and back toward mechanical and quartz heritage pieces. People are tired of their wrists buzzing with notifications. They want the quiet confidence of a steel bracelet that doesn't need to be charged overnight.
Misconceptions About the Tank Française
A lot of people think Cartier watches are delicate. They aren't. They were literally designed with the structure of a military vehicle in mind. You can wear a Tank Française while doing almost anything—though maybe don't wear it while dumping a guy's belongings into the ocean like they did in the movie. Salt water and leather/fine steel don't always mix well without a good rinse.
Another myth? That you need a "watch person" to maintain it. The version in the movie is almost certainly a quartz movement. That means it runs on a battery. It’s low maintenance. It’s for the woman who is too busy to wind a watch every morning but still wants the prestige of a Swiss-made (or French-designed) masterpiece.

Actionable Steps for Capturing the Style
If you are looking to pull off the other woman watch vibe without necessarily dropping four figures on a Cartier, there are ways to do it authentically.
Focus on the Fit
The reason the watch looks so good on Cameron Diaz is the sizing. It’s not loose like a bangle. It’s fitted. If you buy a metal-link watch, take it to a jeweler. Get the links removed until the case sits perfectly centered on your wrist bone.
Mix the Masculine and Feminine
The Tank is a "unisex" design. Pair it with something hyper-feminine, like a silk blouse or a floral dress, to create that Carly Whitten tension. Or, go full "power suit" and let the watch be the only jewelry you wear.
Look for Roman Numerals
The secret to the "Other Woman" look isn't just the shape; it's the dial. Roman numerals add an instant layer of "lawyerly" sophistication. They look academic and established.
Invest in Quality Steel
If you aren't buying Cartier, look for 316L stainless steel. It has a specific luster that doesn't look like cheap chrome. It’s the difference between a watch that looks like a toy and a watch that looks like an heirloom.
The Cartier Tank Française remains a cornerstone of cinematic fashion. It’s more than just a prop; it’s a character study in steel. Whether you're tracking a cheating boyfriend or just trying to make it to your 10:00 AM on time, it’s the gold standard—or rather, the steel standard—for the modern woman.
To truly emulate the aesthetic, start by evaluating your current accessory "armor." Does your watch reflect where you are, or where you want to be? Carly Whitten’s watch was a statement of intent. Your next timepiece should be too. Check the secondary market for "Tank Française Steel" to see the latest valuations, as these pieces hold their price remarkably well compared to other luxury goods.
Keep an eye on the lug-to-lug measurements if you have a smaller wrist; the "Medium" model is often the sweet spot for that 2010s-inspired look. Regardless of the brand you choose, the rectangular silhouette is the key to unlocking that specific blend of 21st-century power and classic elegance.
