Chapters
- 1914 to 1918
From railroad to trench
The US military first noticed Hamilton's accurate pocket watches in 1914. In the First World War, Hamilton railroad watches went to General Pershing's soldiers, converted for the wrist so they could be read at a glance, and in 1917 the company introduced its Grade 983 and 985 Gent's Wrist Watch.
- 1942 to 1945
Every line for the war
In 1942 Hamilton halted all consumer production to build for the armed forces, and it earned five Army-Navy "E" awards for manufacturing excellence. Since 1945 it has kept refining its watches with feedback from servicemen.
- 1967 to late 1980s
The Vietnam-era spec
From 1967 watches built to the GG-W-113 specification, with a 24-hour inner track, were issued in large numbers to American soldiers; Benrus, Bulova and Marathon made them too. Hamilton filled its last US military contract in the late 1980s.
- 1980s to 2000
The soldier's watch goes civilian
The Khaki Field began in the 1980s as Hamilton's civilian version of the GG-W-113. Its 38 mm mechanical model is still the one Gear Patrol calls the most iconic of the Khaki family.
- 2001 to 2013
Hollywood enlists
The line became a film regular: a hand-wound Khaki Field on both pilots in Pearl Harbor (2001), a 38 mm Khaki Field Automatic on Hilary Swank's Amelia Earhart (2009), and a Khaki Field Auto on Chris Evans's Captain America in The Avengers (2012).
- 2014 to today
A message through time
In Interstellar (2014) Cooper leaves his daughter Murph his wristwatch as a keepsake, and the watch ends up central to the plot. The 42 mm Murph went on sale in 2019 with the H-10 80-hour movement and EUREKA in Morse code on the seconds hand, and a smaller 38 mm version followed.

Moments
2026. Two Hamilton watches appear in Steven Spielberg's Disclosure Day, released 12 June 2026: Josh O'Connor's Daniel Kellner wears the Khaki Field Mechanical, while Colin Firth's Noah Scanlon wears a Jazzmaster.
2024. In August 2024 vice-presidential candidate Tim Walz appeared on the campaign trail with a Khaki Field Murph, putting the Interstellar prop watch into American politics; Hamilton CEO Vivian Stauffer said the brand discovered it only when the picture ran.
2019. The Murph launched with an optional tesseract-style box, designed with Interstellar production designer Nathan Crowley and limited to 2,555 pieces.
2019. Hamilton made one change from the film prop: the word Eureka in Morse code printed on the seconds hand, a nod to the film's turning point.
2018. Jack Ryan was Hamilton's first watch placement in a streaming series. Hamilton president Sylvain Dolla said the black Khaki Field Auto Chrono had been flat in sales and went into back order after the series promotion.
1967. The GG-W-113 field watch began reaching American soldiers in large numbers, the template the civilian Khaki Field would later copy almost exactly.
1942. Hamilton halted all consumer production to supply the huge number of watches required by troops.
