Hamilton Khaki Field Murph Automatic 38mm Mens Watch Blue Dial
Ref. H70405140
The Murph began life as a prop for Christopher Nolan's Interstellar, and Hamilton turned the screen-worn design into a production watch that has become one of the more quietly coveted field watches at this size. This blue-dial variant takes the established 38mm format and replaces the familiar black dial with a gradient that moves from a grainy, textured blue at the centre toward near-black at the edges — closer in character to a piece of night sky than to a conventional blue dial. The cathedral hands and domed Arabic numerals carry over from the original, printed in vintage-toned Super-LumiNova that suits the watch's mood better than a crisp white would, even if it charges less aggressively than applied dive-watch indices. At 44.7mm lug to lug and 11.1mm thick, it disappears on smaller wrists in a way the 42mm version cannot, and the H-10 movement inside — a Swiss-made calibre derived from the ETA C07.611, with an 80-hour power reserve and an anti-magnetic Nivachron balance spring — means a long weekend away without winding is not a concern. The bracelet uses Hamilton's Easy Click system, so changing to a strap takes seconds and no tools, which matters more than it sounds on a watch this versatile.

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?
20mm. 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.
Will it fit my wrist?
Lug-to-lug is 44.7mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's, though at 38mm it sits in the range that suits anyone.
