A watch that started life as a movie prop in Christopher Nolan’s Interstellar has just added a new colour to its lineup. The Hamilton Khaki Field Murph 38mm now comes with a blue-to-black gradient dial, and it is priced at ₹113,000 in India.
If you have followed Hamilton’s Khaki Field collection, you already know why the Murph name carries weight. This is the same watch that actor Matthew McConaughey wore on screen while sending Morse code messages across time.
That cinematic backstory is a big part of why this reference, H70405740, matters to collectors and casual buyers alike.

What Is New About the Khaki Field Murph 38mm
The biggest change is the dial. Hamilton has moved away from the plain black and white options and introduced a blue-to-black gradient dial that fades from a bright blue centre to near-black at the edges. The brand says the effect is inspired by the glow of an interstellar comet.
A grained, stardust-style texture runs across the surface of the dial. This adds depth and catches light differently depending on the angle you view it from, which is a small but noticeable upgrade over the flat black dial seen on earlier Murph models.
Everything else about the watch stays familiar. The domed numerals and cathedral-shaped hands, both signature Murph design elements, remain untouched. It is paired with a black leather strap that has contrasting white stitching for a sportier look.

Understanding the Movement and Build
The watch runs on Hamilton’s in-house H-10 automatic movement, built on an ETA C07.611 base. An automatic movement winds itself using the natural motion of your wrist, so there is no need for daily manual winding or a battery.
This particular caliber offers an 80-hour power reserve, meaning the watch can sit unworn over a weekend and still be ticking accurately when you pick it back up on Monday. That is a genuinely useful spec for anyone who rotates between multiple watches.
The case is topped with a sapphire crystal, a scratch-resistant glass that only diamonds can mark. Hamilton has also given it anti-reflective coating on both sides, which keeps glare down when you are checking the time outdoors.
Flip the watch over and you get an exhibition caseback, essentially a transparent window that lets you watch the automatic rotor and gear train in motion. It is a small detail, but one that mechanical watch enthusiasts tend to appreciate.
With 100m water resistance, the Khaki Field Murph 38mm can handle rain, hand washing, and swimming, though it is not built for diving or high-pressure water sports.
Why the Interstellar Connection Still Matters
The original 42mm Murph debuted in 2019 as a tribute to the watch worn in Interstellar, where it became a plot device connecting a father and daughter across time through Morse code. A smaller 38mm version followed in 2022 to suit those who prefer a more compact case.
Since then, Hamilton has expanded the line with white dial and steel bracelet options. This new blue dial version, launched in September 2026, is the first time the Murph has stepped away from a purely black or white colour story, and it leans directly into the film’s space theme.

Should You Care About This Launch
Even if you are not ready to invest in a ₹1 lakh-plus watch right now, this launch is worth tracking for one reason. Hamilton rarely changes the Murph’s dial colour, and this blue execution is the first real departure from black and white since the model’s debut.
For Interstellar fans and mechanical watch collectors in India, this is a fresh reason to revisit a design that has stayed largely unchanged for years.
