This Hamilton Murph review starts with the name itself, which the watch earned honestly. In Christopher Nolan’s Interstellar, Joseph Cooper gives his watch to his daughter Murph before leaving Earth, and the watch later becomes the device he uses to send her the data that saves humanity, communicated through Morse code flashed across its seconds hand. Hamilton built the actual film prop, and five years after the movie’s release, brought a version of that exact watch to market.
This guide covers the Murph’s film history, every current size and configuration Hamilton sells, the movement behind it, and where it lands on price if you are deciding which version is right for you.
The Story Behind the Watch
Hamilton created the original prop watch for Interstellar in 2014, working with production designer Nathan Crowley to build something that could plausibly serve as a plot device. In the film’s key scene, Cooper transmits quantum data across time and space through the watch’s seconds hand, tapping out a message in Morse code that Murph eventually deciphers, prompting her to shout “Eureka.”
Hamilton did not put the watch into regular production until 2019, five years after the film’s release. When it finally arrived, the brand added one small, deliberate detail as a tribute: the word “Eureka” printed in lacquer, in genuine Morse code, on the seconds hand itself. It is barely visible without a loupe, which is part of the appeal for fans who know it is there. The first 2,555 units also shipped in a special tesseract-inspired box designed with Crowley, a number chosen because 2,555 days equals seven years, the same seven years that pass on Earth during one hour on the film’s water planet.
Current Murph Lineup
Hamilton now sells the Murph, part of its broader Hamilton Khaki Field collection, in two case sizes and several strap configurations, all built around the same core design.
Hamilton Murph 42mm (ref. H70605731): The original size, matching the film prop most closely, with a black dial and black leather strap.
Hamilton Murph 38mm (ref. H70405730): Added in 2022 in response to demand for a smaller case, and now the more popular of the two sizes. Same black dial and leather strap as the 42mm.
Hamilton Murph white dial (ref. H70405710): A newer addition with an antique white, grained dial that gives the watch a more vintage look while keeping the same cathedral hands and Morse code detail.
38mm with steel bracelet (ref. H70405130): The black dial 38mm paired with a three-link steel bracelet instead of leather, using polished center links and a milled clasp with micro-adjustment.
Murph Bundle: A package that includes both a leather strap and a steel bracelet with the same watch head, letting you switch looks without buying two separate watches.
Movement and Specs
Every current Murph runs Hamilton’s H-10 automatic movement, based on an ETA 2824-2, with an 80-hour power reserve, enough to sit unworn over a long weekend and still be ready to wear without resetting the time. The case is stainless steel with a sapphire crystal, and water resistance sits at 100 meters across every version.
Dial layouts stay consistent across sizes: cathedral-style hands, applied Arabic numerals, and the Morse code seconds hand detail that ties every current Murph back to the film.
Price and Value
New pricing runs from roughly $995 for the 38mm on leather up to around $1,095 for the 42mm, with the steel bracelet and bundle configurations landing in a similar range. The Murph has become one of Hamilton’s best-selling references, helped by the film connection and a genuinely strong value proposition at this price point.
On the pre-owned market, Murph references typically trade between $350 and $800, reflecting solid value retention for an accessible Swiss watch.

Which Murph Should You Choose?
Choose the 42mm if you want the size closest to the actual film prop and prefer a larger case on the wrist.
Choose the 38mm if you want the more popular current size, which fits a wider range of wrists and has become the version most new buyers choose.
Choose the white dial if you want a lighter, more vintage-leaning look than the original black dial. Choose the steel bracelet or the Bundle if you want the option to wear the Murph as an everyday watch beyond a single leather strap.
