Hamilton Khaki Field Murph Blue Dial: The 2026 "Stardust" Interstellar Watch

The Hamilton Khaki Field Murph blue dial arrives this week as the most atmospheric version yet of the watch made famous by Christopher Nolan's Interstellar (see our Hamilton brand history) — a new "Stardust" variant whose gradient dial fades from a luminous blue center to black at the edges. Priced from $995, it joins rather than replaces the existing black and white dial models, and keeps the compact 38mm case and the 80-hour Hamilton H-10 automatic that made the Murph one of the most talked-about field watches under $1,000.

For collectors, the appeal is immediate. This is the same Khaki Field watch that appeared on Murphy "Murph" Cooper's wrist in one of modern science fiction's most emotionally charged plot devices — now dressed in a dial that reads like a photograph of an ionized interstellar cloud. The question is whether the blue "Stardust" version earns its place alongside the originals, or simply gives long-time fans a fresh reason to buy.

The New Hamilton Khaki Field Murph Blue Dial Explained

The headline change is the dial itself. Hamilton has built a gradient that begins as a deep, luminous blue at the center and darkens gradually to black toward the rehaut, evoking the journey of an interstellar comet or a field of ionized gases. Across that gradient sits a strong grained "stardust" texture that catches light unevenly, so the surface shifts from near-solid at the perimeter to glowing at the core depending on the angle.

Legibility remains pure Khaki Field. Beige printed Arabic numerals and a matching beige minute track ride over the blue gradient, paired with cathedral-style nickel-plated hour and minute hands and a nickel-plated seconds hand. Super-LumiNova coats the handset and numerals for low-light reading. It is a warmer, more vintage-military color palette than the icy blue dials common elsewhere, which keeps the watch tied to its tool-watch roots even as the dial turns cinematic.

Hamilton Murph 38mm Case and H-10 Movement

The case is unchanged, which is a good thing: the Khaki Field Murph measures 38mm in diameter, 11.1mm thick, and 44.7mm lug-to-lug, with curved lugs and brushed-and-polished stainless steel surfaces. A sapphire crystal with anti-reflective coating protects the dial, a sapphire display caseback reveals the movement, and water resistance is rated to a practical 100 meters — enough for daily wear and the occasional swim.

Inside is the Hamilton H-10 automatic, based on the Swatch Group Powermatic 80 architecture. It offers an 80-hour power reserve — a genuine three-day-plus runtime that lets the watch sit off the wrist over a long weekend — beats at 21,600 vibrations per hour, and uses a Nivachron balance spring for improved resistance to magnetism and temperature. At this price, an 80-hour reserve with an antimagnetic hairspring is a standout technical specification.

References, Pricing, and Where It Sits Under $1,000

The blue "Stardust" Murph launches in two configurations. Reference H70405740 comes on a black croc-embossed leather strap at $995 , while reference H70405140 ships on a three-row stainless steel bracelet at $1,045 . That $50 walk-up for the bracelet is one of the easiest upgrade decisions in the category.

• Ref. H70405740 — Black Croc-Embossed Leather Strap $995
• Ref. H70405140 — Three-Row Stainless Steel Bracelet $1,045

At this money, the Murph is a strong entry in the sub-$1,000 field-watch space, where its 80-hour H-10 movement, sapphire crystal, and 100m water resistance outrun much of the competition on paper. Shoppers weighing it against rivals will find useful context in our best watches under $1,000 guide, and anyone tempted to stretch the budget can compare it in our best watches under $2,000 roundup.

Blue vs. Black vs. White: How the Dials Compare

★ The blue "Stardust" dial joins the lineup as a new standard-production variant; it does not replace the black or white versions. Prices for existing dials are approximate and vary by strap.

The Interstellar Connection: Why It Is Called the Murph

The Khaki Field Murph exists because of Christopher Nolan's 2014 film Interstellar. In the story, astronaut Cooper leaves the watch with his young daughter, Murphy "Murph" Cooper, before departing on his mission. Years later, from inside the tesseract, Cooper uses the watch's seconds hand to transmit the quantum data needed to solve gravity, tapping it out in Morse code for an adult Murph to decode. The running seconds hand is not a detail — it is the plot's emotional and scientific hinge.

That is why Hamilton keeps the nickel-plated seconds hand and the cathedral handset front and center on every Murph, blue "Stardust" dial included. Hamilton has a long history of on-screen watches, and the Murph remains its most narratively significant. The blue gradient simply pushes the cosmic theme further, turning the dial into a small window on the interstellar setting the watch came from.
