Hamilton Hamilton Khaki Field Murph H70405130 H70405130

The Hamilton Khaki Field Murph H70405130 is the 38mm, black-dial, steel-bracelet reference in Hamilton's Khaki Field Murph line — a field watch built around the prop Hamilton originally created for Christopher Nolan's 2014 film Interstellar. It runs the automatic Caliber H-10, a modified ETA C07.611, with an 80-hour power reserve, and retains the film-specific detail of a Morse code "Eureka" message worked into the seconds-hand lume.

Hamilton was commissioned by the producers of Christopher Nolan's 2014 film Interstellar to build a custom watch for the story's central prop: the watch protagonist Cooper (Matthew McConaughey) leaves with his daughter Murph before departing on the film's space mission. According to Strapcode, Hamilton was tasked with creating the watch within roughly three weeks. Teddy Baldassarre's owner review likewise notes the watch "was originally created as a custom piece for the movie," with the seconds hand carrying a detail that became the piece's defining feature.

That detail is a Morse code message — "Eureka" — worked into the lume plots on the seconds hand. In the film, Cooper transmits this message from inside a tesseract to communicate the data that resolves the plot's central problem, making the watch a plot device rather than a background prop.

Hamilton brought the watch to market in 2019, five years after the film's release, as the 42mm Khaki Field Murph (ref. H70605731). Monochrome Watches reports it launched at EUR 895 with a tesseract-inspired special packaging, co-designed with the film's production designer Nathan Crowley, limited to 2,555 units — the packaging was limited, not the watch itself, which remained in ongoing production.

A smaller-cased line followed. Teddy Baldassarre's review of the 38mm version describes it as "a significant improvement over the original 42mm release," placing the case in what the reviewer calls the field-watch sizing sweet spot. H70405130 — black dial on a steel bracelet — is one reference within that 38mm line.

The Murph runs Hamilton's Caliber H-10, an automatic movement built on the ETA C07.611 platform, per Caliber Corner. The C07.611 belongs to Swatch Group's Powermatic 80 family, which Monochrome Watches notes was based on the ETA 2824-2. The movement carries 25 jewels, beats at 21,600 vph (3 Hz), measures 25.6mm / 11.5 lignes across, and uses a Nivachron balance spring — a titanium-based alloy chosen for its resistance to magnetic interference — along with Nivashock shock protection.

Hamilton's headline gain over a standard ETA 2824-2 is power reserve: where Monochrome Watches notes a normal 2824-2 runs for about 38 hours, the H-10 is tuned to 80 hours, achieved in part by slowing the balance frequency. Caliber Corner notes the movement supports hand-winding and hacking seconds, and is bidirectionally wound via a ball-bearing-mounted rotor.

Teddy Baldassarre's review calls out the exhibition caseback on the 38mm Murph, through which the H-10's finishing is visible, while suggesting the field-watch styling would also have suited a closed caseback. The reviewer reports the movement kept good time over roughly two years of ownership.

Teddy Baldassarre's owner review measures the 38mm Murph's lug-to-lug at 44.7mm and describes the case proportions as hitting "the almost universally accepted sweet-spot" for a field watch, wearing, in the reviewer's words, similarly to a Seiko in terms of comfort and scale. The reviewer characterizes the dial as a duality: rugged field-watch cues (Arabic numerals, cathedral hands) paired with a near-dressy matte presentation that reads as more refined than a typical field watch.

Dappered's review of the steel-bracelet configuration — the same build as H70405130 — reports it worn on a 7.5-inch wrist at 38mm width and 11.1mm thickness, noting it "slides easily under a shirtcuff" and reads as comfortable for all-day wear. The reviewer describes the crown as winding with "distinct feedback" and the three-link bracelet as articulating smoothly, with brushed center links against polished edges that mirror the case finishing; the main criticism raised is the clasp's reliance on tool-adjusted micro-sizing holes rather than an on-the-fly extension.

Barrels & Balance, reviewing the white-dial 38mm variant, describes the case as "compact but not diminutive," suitable across a range of wrist sizes and able to move between casual and business contexts.

Teddy Baldassarre's review flags two criticisms that apply to the 38mm line generally: the leather strap is stiff out of the box (attributed to it being a close recreation of the film-worn strap), and the lume performance is described as weak, without a bright, sustained glow.

The Khaki Field Murph began as a 42mm model (ref. H70605731) at its 2019 launch, per Monochrome Watches: stainless steel case, sapphire front and back (exhibition caseback), 100m water resistance, black dial with nickel-coated beige Super-LumiNova hands, and a black leather strap on a steel pin buckle. That launch edition shipped in a limited tesseract-styled box of 2,555 units, though the watch itself was not a limited edition.

Hamilton subsequently introduced a 38mm case size to the line. Teddy Baldassarre's review covers both black and white dial versions on leather, priced at $945, alongside a steel-bracelet configuration at $995 at the time of that review. Barrels & Balance separately reviews the white-dial 38mm-on-leather configuration, noting the absence of a date window as consistent with the line's minimalist field-watch styling. H70405130 is the black-dial, steel-bracelet reference within this 38mm range.

H70405130 — the 38mm, black-dial, steel-bracelet Murph — carries a U.S. list price of $1,045, confirmed independently by authorized Hamilton retailers Reeds Jewelers and Mayors. That sits above the leather-strap 38mm configurations, which Teddy Baldassarre's review lists at $945–$995 at the time of that review, reflecting the added cost of the steel bracelet.

The reference is sold through Hamilton's own site and a network of authorized jewelers and watch retailers; it is not a limited edition, unlike the special tesseract-box packaging that accompanied the original 42mm launch model. As with much of Hamilton's catalog, authorized dealers periodically discount the reference — Watchmaxx, for example, lists it at $859 against a stated $1,045 retail, an 18% markdown — so buyers comparing prices should expect variation between full retail and discounted authorized-dealer pricing rather than a single fixed street price.
