The Interstellar Watch That Crossed the Divide Between Cinema and Reality

Cinema and fashion have long shared a symbiotic relationship. Clothing and accessories worn in iconic films do more than support narratives—they often become cultural artifacts in their own right. Think of Audrey Hepburn’s little black dress in Breakfast at Tiffany’s, or James Dean’s red jacket in Rebel Without a Cause. These aren’t just costumes—they’re emblems of emotion, memory, and identity.

In that same lineage of iconic screen-worn objects comes the Hamilton Khaki Field “Murph” Auto. Known affectionately by fans as the “Murph Watch,” this timepiece made its indelible mark in Christopher Nolan’s 2014 science fiction epic Interstellar. It was worn by the film’s protagonist, Cooper, portrayed by Matthew McConaughey. More than just a prop, the watch played a pivotal narrative role, becoming a symbol of hope, connection, and the mysterious elasticity of time.

So profound was its impact that Hamilton answered fan demand by releasing the “Murph” watch as a commercial product in 2019. Now a staple in the brand’s lineup and a talismanic artifact for film lovers and horology enthusiasts alike, the Murph Auto continues to symbolize the intersection of time, emotion, and storytelling. As Hamilton celebrates its 130th anniversary, the Murph Watch stands as a reminder of how timepieces can be more than instruments—they can be icons.

A Century and More of Hamilton: American Roots and Cinematic Dreams

Founded in Lancaster, Pennsylvania in 1892, Hamilton has long been a pivotal force in American timekeeping. The brand first earned renown for its accuracy and reliability during the rise of the U.S. railroad industry, later expanding into military and aviation applications. During both World Wars, Hamilton supplied the U.S. Armed Forces with precise, rugged watches that helped cement its status as a trusted manufacturer. In the post-war years, the company expanded its reach to the burgeoning consumer market—and eventually, to Hollywood.

Hamilton’s relationship with cinema began in earnest in the 1950s and 1960s, when their watches started appearing on the wrists of silver screen heroes. Elvis Presley wore the Ventura in Blue Hawaii (1961), and since then, Hamilton watches have adorned characters in more than 500 major motion pictures. But perhaps no watch has captured the public imagination quite like the Murph.

The Role of the Murph Interstellar: Time as a Language of Love

In Interstellar, time is not just a setting or a mechanic—it’s a theme, a character, and a paradox. Nolan’s masterpiece uses the theory of relativity to explore emotional weight: the distance between father and daughter, the promises that echo across dimensions, and the idea that love, like gravity, can transcend time and space.

The Murph Watch is given to Murphy (Murph), Cooper’s daughter, as he prepares for a space mission. When Cooper departs Earth, Murphy is left behind with the watch—a symbolic inheritance. Later in the film, Cooper uses quantum mechanics to manipulate the ticking of the watch from inside a tesseract, transmitting a message in Morse code back through time. The moment is both technical and poetic: time, encoded through the beat of seconds, becomes a vessel for love and redemption.

The watch’s appearance is subtle, almost modest. A black dial, beige Super-LumiNova numerals, and a 42mm stainless steel case—nothing about it screams for attention. Yet it becomes the centerpiece of one of the most emotionally resonant scenes in the film. It is, quite literally, the key to saving the human race.

From Fiction to Reality: Fan Demand and Hamilton’s Response

After the release of Interstellar, fans of the film became fixated on the watch. Online forums buzzed with speculation: Was it a real Hamilton model? Could it be bought? How closely did it resemble existing field watches? For years, enthusiasts clamored for an official release—and in 2019, Hamilton delivered.

Dubbed the Khaki Field Murph Auto, the production model remained faithful to the on-screen original. The black dial, cathedral-style hands, and beige minute track were all retained. The movement inside is Hamilton’s H-10 automatic caliber, offering an impressive 80-hour power reserve. Even more special: hidden on the second hand is the word Eureka, printed in lacquered Morse code—a nod to the precise moment Murph deciphers her father’s message in the film.

This subtle detail elevated the Murph from homage to artifact. It was no longer just a watch—it was a narrative in miniature.

The Design Language of the Murph: Understated Brilliance

The Murph is part of Hamilton’s broader Khaki Field collection—a series inspired by the brand’s military heritage. Unlike the chunkier, tactical watches often associated with military styling, the Murph balances ruggedness with refinement.

Its 42mm case wears comfortably on the wrist, while the sapphire crystal ensures durability without sacrificing visibility. The dial layout is clear and legible, with Arabic numerals rendered in vintage-style beige for a timeless look. The lack of a date window is a deliberate choice, preserving the visual integrity of the film version.

The leather strap—black with white stitching—further grounds the watch in both functionality and emotion. This isn’t a luxury timepiece meant to dazzle; it’s a tool, a companion, and a narrative device. Its modesty is part of its charm.

A Watch with Layers: Technical Specs and Symbolic Value

• Movement: H-10 automatic (base ETA C07.611)
• Power Reserve: 80 hours
• Case Size: 42mm
• Case Material: Stainless steel
• Dial: Black with beige Super-LumiNova indices
• Water Resistance: 100 meters
• Crystal: Sapphire
• Strap: Black leather with pin buckle

But beyond the specs, what makes the Murph so special is how it bridges science and sentiment. It’s a testament to how technical precision—when wielded with narrative power—can transform a simple object into something profound.

Time Travel in the Everyday: Wearing the Murph Today

There’s something poetic about wearing the Murph in daily life. For fans of the film, it’s a wearable memory, a nod to one of modern cinema’s most poignant sci-fi narratives. But even for those unfamiliar with Interstellar, the watch stands tall as a symbol of perseverance, ingenuity, and quiet strength.

It appeals to watch collectors, film aficionados, scientists, storytellers, and romantics alike. It doesn’t demand to be recognized—it invites discovery. And once you learn its story, you’re drawn deeper into the watch’s orbit.

The 38mm “Murph Mini”: A New Chapter

In 2023, Hamilton introduced a 38mm version of the Murph, answering another wave of fan demand. This slightly smaller edition preserves all the details of the original while offering a more versatile fit for a broader range of wrists.

The move not only reaffirmed Hamilton’s attentiveness to its community but also demonstrated the continued relevance of the Murph story. It wasn’t a one-time novelty—it was evolving, like all great narratives do.

Hamilton at 130: Celebrating Legacy Through Cinema

In 2025, Hamilton celebrates its 130th anniversary—a milestone few brands reach with such cultural vitality intact. The company’s ability to balance heritage with innovation is a key reason why it remains at the forefront of both horology and cinematic design.

The Murph Auto represents the perfect encapsulation of Hamilton’s values: historical depth, technical excellence, and emotional storytelling. It is a bridge between worlds—between science and fiction, between past and future, and between people separated by light-years.

Impression: A Watch That Measures More Than Time

Watches are often described as tools that measure time. But the Murph does more. It measures meaning. It embodies the emotional architecture of a film that dared to explore cosmic questions through human intimacy. It asks us to believe that time is not just a sequence of minutes and hours, but a medium through which we can connect, communicate, and endure.

When you wear the Murph, you wear a story—one that spans galaxies, but also touches something deeply personal. It reminds you that even in the vastness of space, a heartbeat of time can echo across generations.
