Hamilton Khaki Field Murph Automatic Watch 38mm in Blue-to-Black Dial - H70405740

Hamilton H70405740 Khaki Field Murph Automatic Watch 38mm in Blue-to-Black Dial

A new expression of the Murph, the Hamilton Khaki Field Murph 38mm Automatic H70405740 brings cosmic color to an iconic cinematic timepiece. Created for Christopher Nolan's "Interstellar," the Murph became the watch that connected a father and daughter across time. Its emotional link to the film and faithful field-watch character made it a favorite among enthusiasts, while the compact 38mm format opened a new chapter for collectors who wanted the recognizable design in a smaller size. This edition continues that story with fresh visual depth and the same sense of character and purpose.

The blue-to-black dial draws inspiration from an interstellar comet. A luminous blue center recalls the glow of ionized gases in space, then fades into black at the edge to suggest the depth of the interstellar void. A grained texture inspired by stardust gives the surface added dimension as the light changes. Slightly domed numerals and cathedral-shaped hands preserve the Murph's signature look, while a black calf leather strap with contrasting white stitching completes its classic, cinematic expression.

Beyond its screen heritage, this Hamilton automatic watch is built for everyday timekeeping. The three-hand H-10 caliber offers an 80-hour power reserve, and its Nivachron balance spring supports dependable performance in the presence of magnetic fields, temperature changes and shocks. Super-LumiNova details help keep the display readable in darkness. A stainless steel case, scratch-resistant sapphire crystal with anti-reflective treatment and an open case back balance durability with a view into the mechanical design. Together, these elements make the Murph a distinctive choice for film-watch collectors, Hamilton enthusiasts and anyone seeking a versatile automatic field watch with a cosmic point of view.

Key Features

From the Set to Your Wrist

The original Khaki Field Murph was crafted exclusively for "Interstellar" and was not initially intended to move beyond the movie set. Requests from fans around the world led Hamilton to bring the screen watch to life, recreating its defining details for enthusiasts drawn to both its film accuracy and emotional significance. The Murph 38 later answered years of interest in a smaller interpretation of that celebrated design.

H-10 Caliber

As the wearer moves, an internal rotor swings and channels energy to the mainspring, powering the timepiece without a battery. The H-10 is a three-hand automatic movement engineered with an extended 80-hour power reserve.

Nivachron Balance Spring

The Nivachron alloy balance spring is designed to resist magnetic fields while reducing the effects of temperature fluctuations and shocks. These protective qualities help improve the movement's accuracy under changing everyday conditions.

Sapphire Crystal

Synthetic sapphire forms a tough, scratch-resistant barrier over the dial; Hamilton notes that only diamonds could leave a mark. Anti-reflective treatment further supports a clear view of the stardust-inspired surface and sculpted display.
