On Spec: Hamilton Khaki Field Murph 38mm

In 2014, Christopher Nolan released the cinematic masterpiece, Interstellar. To summarize the film, a team of explorers travel through a wormhole in space to ensure humanity’s survival from a now-dying Earth. One of the critical props throughout Interstellar is a one-off watch created by Hamilton, referenced as the “Murph.” The director, Christopher Nolan, and production designer, Nathan Crowley, commissioned the watch as a prop to demonstrate time travel. During the movie, the watch is given to Murph Cooper (Mackenzie Foy) by her father, Coop (Matthew McConaughey), before he leaves on a mission to find a habitable planet for humankind to thrive.

The new Hamilton made watch enthusiasts speak up, wanting a full-production model of the Murph. Fast forward to 2019–yes, it took five years for a production model to be released–and the Murph became available for purchase. The Murph isn’t much different in dial design than the standard Khaki field mechanical. The Murph has a 42mm stainless steel case, a very stiff calf-skin leather strap, and a beautiful fauxtina black dial. On the second hand, there is a section of Morse code on the original Murph, which translates to “Eureka,”–the word used to signify a crucial moment in the film. Fans of the movie loved this watch; however, there was the harken to make a smaller version, as 42mm is on the larger side for most.

The Hamilton Khaki Field Murph 38mm Watch Review
The compact and elegant new Murph

That’s where the update comes in. On November 22nd, 2022, Hamilton listened to the people and released a smaller 38mm cased version of the Murph. With a lug to lug length of 44.7mm and a thickness of 11.1mm, this new version is compact, elegant, and carries the same looks as its bigger 42mm brother. The main difference is that the Morse code is removed from the second hand on the 38mm version. While some people think the Morse code should have stayed, I think it’s an excellent call by Hamilton to remove it since it’s not the exactly the same watch as seen in the film.

The Murph retails for $895USD. For more information on the Murph, please visit the brand website.
