Hamilton Khaki Field Murph Automatic 42mm Unisex Watch Black Leather Strap and Bracelet Box Set
Ref. H70605732
Sits in Hamilton’s upper tier here — more premium than three quarters of the Hamilton watches we list, which start at £375.
Price range £375 to £2,265 across 72 Hamilton watches in stock.The Murph began as a prop — Hamilton built it for Christopher Nolan's *Interstellar*, and it became the centrepiece of the film's central conceit: Cooper tapping out data in Morse code through the seconds hand to his daughter across dimensions, the word "Eureka" rendered in lacquer on that same hand. That is not marketing mythology grafted on later; it was designed into the watch from the start. The Field collection behind it has genuine military roots, Hamilton having supplied the U.S. Air Force with field watches through the 1960s and 1970s, and soldiers before that in the 1940s. The Murph inherits the utilitarian Arabic numerals, cathedral hands and satin-finished case that came from that tradition. The H-10 inside is built on the ETA C07.611 and wound to an 80-hour reserve, which means leaving it on a Friday evening and picking it up Monday morning without touching the crown. The dial carries inner 24-hour markings that most owners take a week to notice, and the see-through caseback puts the movement in view whenever the watch comes off. This box set pairs the watch with both a black leather strap and a stainless steel bracelet on the same 22mm lug, so it is genuinely two configurations rather than a dressed-up single option. Given where the leather and the bracelet each sit aesthetically, the watch reads quite differently between the two.

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 comparedWhat 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.
Will it fit my wrist?
Lug-to-lug is 53mm, which suits wrists from roughly 17.5cm (7 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 unisex, and at this size it suits any wrist that takes the dimensions.
