Will Smith is alone. Well, he’s got Sam, the German Shepherd who basically stole every scene in that 2007 flick. But in the eerie, overgrown silence of a post-apocalyptic New York City, time is actually the biggest villain. That’s why the I Am Legend watch—the Hamilton Khaki Twilight—became such an obsession for gearheads and movie buffs alike. It wasn't just a prop. It was a lifeline.
If you’ve watched the movie lately, you know the drill. Robert Neville is a man governed by the sun. When that watch beeps, it isn't telling him he's late for a meeting. It’s telling him he has exactly enough time to get behind a steel shutter before the Darkseekers come out to play. Most movie watches are just product placement, but this one felt different. It felt heavy.
The Hamilton Khaki Twilight: More Than Just a Pretty Face
Hamilton has a weirdly long history with Hollywood. They’ve been in everything from Interstellar to Men in Black. But the I Am Legend watch is a bit of an oddity. Officially called the Hamilton Khaki Twilight (Reference H62515133), it was designed specifically to track the transition from day to night.
Think about that for a second.
In a world where the sun dictates whether you live or die, a watch that tracks "civil twilight" is incredibly grim. It’s cool, sure. But it’s dark. The watch features a unique complication that shows the countdown to sunset and sunrise. Specifically, it was calibrated for New York City. The dial has these internal rotating rings that adjust for the date, showing you exactly when the sky is going to turn that dangerous shade of purple.
The watch is a beast. 44mm. It’s got this massive crown guard that looks like it could take a hit from a mutant and keep ticking. It runs on the ETA 2893-2 automatic movement, which is a workhorse. It’s reliable. You don't want a battery dying when you’re hiding in a bathtub with a dog and a shotgun.

Why the Twilight Model is So Hard to Find Now
Honestly, trying to buy one of these today is a headache. Hamilton discontinued the Twilight years ago. Because it was such a niche complication—most people don't actually need to know the exact minute of sunset in NYC—it didn't stay in the catalog forever.
If you go looking for the I Am Legend watch on the secondary market, you’re going to see prices all over the map. Sometimes they pop up on eBay or Chrono24 for $900. Other times, collectors who know what they have will list them for well over $1,500.
There's also a bit of confusion. Robert Neville actually wears two different watches in the film. While the Twilight is the one everyone talks about because of the "sunset" theme, he’s also seen wearing a Hamilton Khaki Expedition on a brown leather strap. It’s a cleaner, more classic field watch. It doesn't have the crazy crown guard or the twilight sub-dial, but it fits the "rugged survivor" aesthetic perfectly.
The Symbolism of Time in a Dead World
Movies use watches to ground the character. In I Am Legend, the watch represents Neville's last shred of sanity. Without the beep, he's just a guy wandering around with a dog. The watch is his discipline. It’s his military background manifesting as a piece of steel on his wrist.
When he looks at that dial, he isn't just checking the time. He's measuring his survival window. The cinematography does a great job of focusing on the ticking hands. It builds tension. It makes the audience feel that same frantic "I need to get home" energy.

Interestingly, the watch in the movie isn't exactly the same as the one you’d buy at a jeweler. Movie props are often modified. Sometimes they're "relumed" so the glow-in-the-dark bits pop more on camera. Other times, the sound of the beep is added in post-production to make it sound more high-stakes. The real Hamilton Twilight doesn't actually beep like a digital Casio; it's a mechanical watch. That’s a classic Hollywood "lie" that always bugs the purists.
Other Watches That Share the Vibe
If you can't find a Twilight, or you don't want to drop two grand on a used watch from 2007, there are alternatives. The whole "Khaki" line from Hamilton is basically the gold standard for this look.
- The Khaki Field Mechanical: This is the purist's choice. 38mm, hand-wound, looks like something from WWII. It doesn't have the sunset dial, but it has the soul.
- The Khaki Navy Frogman: If you liked the chunky, "I can survive anything" look of the Twilight's crown guard, the Frogman is its spiritual successor. It's built like a tank.
- Seiko Alpinist: A bit of a curveball, but it has that internal rotating bezel and a rugged, adventurous feel that fits the Neville character.
Real-World Specs for the Nerds
Let's talk technicals for a minute. The Twilight has a sapphire crystal, which is basically scratch-proof. Good for scavenging for canned goods in a ruined Grand Central Station. The water resistance is 200m. The GMT function (the fourth hand) is used here not for a second time zone, but to help drive that twilight calculation.
The strap on the movie version was a black rubber or synthetic material. It’s practical. Sweat, blood, rain—it doesn't matter. Leather would rot in that New York humidity after a few years without maintenance.
It’s also worth noting the dial color. It’s a deep black with high-contrast white numerals. Legibility is king. When you’re sprinting away from a group of "Hemocytes," you don't want to be squinting at a complicated chronograph. You want to see the time, instantly.

The Legacy of the I Am Legend Watch
Even though the movie is nearly two decades old, the interest in Neville's gear hasn't faded. People still haunt forums looking for the specific jacket he wore (Belstaff, by the way) and the specific watch.
Maybe it's the "prepper" trend. Or maybe it's just that the watch is genuinely cool. It represents a time when watch companies were willing to experiment with weird, specific complications that served a narrative purpose.
Is it the best watch Hamilton ever made? Probably not. Is it the most iconic? For a certain generation of moviegoers, absolutely. It’s a piece of cinema history that you can actually wear—if you can find one.
How to Track One Down
If you're serious about owning the I Am Legend watch, you have to be patient.
- Set up alerts on WatchRecon and eBay. Use terms like "Hamilton H62515133" and "Hamilton Khaki Twilight."
- Check the forums. Watchuseek and Reddit's r/Watches often have private sellers who are more reliable than random eBay listings.
- Verify the movement. If someone is selling a "Twilight" that takes a battery, it's a fake or a very different model. The real deal is a mechanical automatic.
- Look at the crown guard. The Twilight has a very specific, hinged locking mechanism. If it looks like a standard screw-down crown, it's a different Khaki model.
There is something inherently cool about a watch that was designed for a world that ended. It’s a reminder that even when everything else goes to hell, the gears keep turning. Robert Neville might have been the last man on Earth, but at least he knew exactly when the sun was going down.
If you’re looking to scratch that survivalist itch, start with the Hamilton Khaki Field line. It’s the most accessible way to get that Robert Neville look without having to scour the globe for a discontinued 20-year-old timepiece. Stick to the mechanical versions for that authentic, "no batteries in the apocalypse" feel. You'll want a sturdy NATO strap to go with it—black or olive drab works best for staying low-profile in the ruins of midtown. Check the lugs for 20mm or 22mm spacing before you buy, as Hamilton varies these across the Khaki range. Once you have the kit, all you need is a loyal dog and a very fast car.
