Sold out

The Hamilton Khaki Field Murph H70605732 is the watch that played a central role in Christopher Nolan’s Interstellar — the timepiece Murph Cooper used to receive quantum data from her father across dimensions. A 42 mm brushed steel case with a matte black dial, patina cream numerals, cathedral hands and “EUREKA” in Morse code along the seconds hand, paired with Hamilton’s H-10 automatic movement and an 80-hour power reserve.

The H70605732 is Hamilton’s Khaki Field Murph — the watch that played a starring role in Christopher Nolan’s 2014 film Interstellar, where it sat on Murph Cooper’s wrist and served as the literal plot device used to transmit quantum data from inside a tesseract to a daughter on Earth. Hamilton developed the design with the film’s production team rather than supplying an off-the-shelf model, then put it into public production after the movie’s release on the back of overwhelming fan demand. More than a decade on, it remains one of the most recognised film watches of the last 25 years — alongside the Omegas of James Bond and the Heuer Monaco of Le Mans.

The case is what made the original work on screen: a 42 mm brushed-and-polished stainless steel case, 11 mm thick, with an oversized push-pull crown that’s easy to grip with gloves or wet hands, fixed smooth bezel, sapphire crystal up front and an exhibition case back so the H-10 movement stays visible. The dial is matte black with patina-cream Arabic numerals at every hour, a railroad minute track around the outer rim, luminous cathedral hands in matching cream tone, and a single design detail that’s pure film prop: “EUREKA” — the breakthrough word from the script — printed in Morse code along the seconds hand, where Cooper used the watch’s tick to send his message. The whole package reads as a clean, vintage-leaning field watch first and a film tribute second, which is the reason it works as everyday wear rather than as a costume piece.

Under the case back sits Hamilton’s H-10 calibre, the brand’s modified ETA C07.611 automatic, and this is where the watch quietly outpunches its price bracket. By lengthening the mainspring and lowering the beat rate to 21,600 vph, Hamilton extends the power reserve to 80 hours — meaning the watch can sit unworn from Friday evening to Monday morning and still be running on time when you pick it up, where most automatics in this segment top out around 38–42 hours. Twenty-five jewels, automatic winding, hours-minutes-seconds with no date window to break the dial’s symmetry, and 10 bar (100-metre) water resistance round out the package — a Khaki Field built around a movie role but engineered to outlast the reference to it.
