Stepping up in the same colour and case shape
The Murph takes its name and its brief directly from Christopher Nolan's Interstellar: it is a faithful reconstruction of the watch worn by the film's central character, and Hamilton — long embedded in Hollywood's prop houses — produced it as a piece that works in both directions, as a screen-accurate object for those who care about the film and as a proper field watch for those who do not. The detail that rewards a close look is on the seconds hand: the lacquer decoration printed along it spells "Eureka" in Morse code, invisible at a glance and quietly there once you know it. Beyond that, the dial is a straightforward field watch proposition — beige Arabic numerals on black, cathedral hands, the kind of high-contrast legibility the format exists to provide. The H-10 movement inside is Hamilton's longest-running calibre, built on a proven Swiss base and wound to an 80-hour reserve, which means a watch taken off on Friday evening is still running Monday morning. The Nivachron balance spring adds magnetic resistance that most field watches of this type do not carry, and the exhibition caseback means the movement is on view — a sensible detail on a watch whose backstory is already worth examining.

Learn more about Hamilton
Hamilton was founded in Lancaster, Pennsylvania in 1892, and its early business was the railroad. American rail accidents caused by unsynchronised timekeeping had forced the industry to adopt strict standards, and Hamilton built pocket watches accurate enough to meet them — earning the description the watch of railroad accuracy.
Two things then defined it. The first was war: Hamilton supplied over a million watches to American forces in the Second World War, suspending civilian production entirely, and its marine chronometers were fitted across the US Navy.
The second was electricity. The Ventura of 1957 was the first battery-powered electric wristwatch, and its asymmetric shield-shaped case, designed by Richard Arbib, looked like nothing before it. Elvis Presley wore one in Blue Hawaii.
Hamilton's cinematic presence is unusually deep — over five hundred films — and includes the watches designed for 2001: A Space Odyssey with Stanley Kubrick, and appearances in Interstellar and Tenet.
American manufacturing ended in 1969 as the quartz crisis approached. The brand was acquired by the Swiss and is now part of the Swatch Group, based in Biel, where it occupies a distinctive position: American design heritage, Swiss production, and ETA movements with long power reserves at accessible prices. The Khaki Field, descended from the wartime issue watches, is its best-known line.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 80 hours fully wound — enough to sit off the wrist over a weekend and still be running.
What size strap does it take?
22mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as men's.
