Hamilton has been the watchmaker of choice for major Hollywood films for decades. From Stanley Kubrick’s 2001: A Space Odyssey to Interstellar to multiple Indiana Jones adventures, the brand has consistently found its way onto leading wrists in iconic productions. As a result, when news broke that two Hamilton watches would appear in Steven Spielberg’s upcoming thriller Disclosure Day, collectors took notice immediately.
The film releases on June 12, 2026. Meanwhile, the watches featured are both already available, which means buyers can own the exact pieces worn on screen rather than wait for limited edition tie-ins.
About Disclosure Day
Disclosure Day is Steven Spielberg’s latest thriller, set to debut June 12, 2026. The film centers on whistleblower Daniel Kellner, played by Josh O’Connor, who teams up with meteorologist Margaret Fairchild (Emily Blunt) to disclose the existence of aliens on Earth. Meanwhile, high-ranking government officials including Noah Scanlon (Colin Firth) work to prevent the disclosure and the disruption of order it would cause.
Both Kellner and Scanlon wear Hamilton watches throughout the film. As a result, the two timepieces become subtle character signals: one defined by clarity and restraint, the other by refinement and complexity.
For more on Hamilton’s broader connection to film, our coverage of Hamilton watches at Precision Watches covers the brand’s current lineup of Hamilton watches across the Khaki and Jazzmaster collections.
The Hamilton Khaki Field Mechanical 38mm (ref. H69409930)
Josh O’Connor’s character, Daniel Kellner, wears the Hamilton Khaki Field Mechanical 38mm throughout the film. This watch has been a long-running favorite among collectors and film costume designers alike for its military-inspired simplicity and hand-winding movement.
Key specifications:
- Case diameter: 38mm
- Lug-to-lug: 47mm
- Thickness: 9.5mm
- Case material: Stainless steel with black PVD coating
- Crystal: Sapphire
- Dial: Black with white-printed Arabic numerals and Old Radium Super-LumiNova indexes
- Movement: Hamilton Calibre H-50 (manual winding, 80-hour power reserve, 21,600 vph)
- Water resistance: 50 meters
- Strap: Dark gray NATO with black PVD-coated steel buckle
- Price: $945
The Khaki Field Mechanical is one of the strongest values in entry-level Swiss mechanical watchmaking. As a result, it fits Kellner’s character: a whistleblower defined by purpose and a direct relationship with time. Meanwhile, the 80-hour hand-wound H-50 movement keeps the watch running across multiple days off the wrist, which is practical detail meaningful for daily wear.
For collectors wanting a deeper look at this reference, the 38mm proportions also make it one of the most universally wearable field watches on the market today. The Old Radium lume gives the dial a vintage warmth that pairs particularly well with the black PVD case.
The Hamilton Jazzmaster Open Heart Auto 40mm (ref. H32675540)
Colin Firth’s character, Noah Scanlon, wears the Hamilton Jazzmaster Open Heart Auto 40mm. This is a meaningful character contrast to the simpler Khaki Field Mechanical worn by O’Connor’s character.
Key specifications:
- Case diameter: 40mm
- Lug-to-lug: 48mm
- Thickness: 11.05mm
- Case material: Stainless steel (brushed and polished)
- Crystal: Sapphire with anti-reflective coating
- Dial: Blue fumé with gradient to black, applied indexes, partially open-worked
- Movement: Hamilton Calibre H-10 (automatic with manual winding and hacking, 80-hour power reserve, 25 jewels, Nivachron hairspring)
- Water resistance: 50 meters
- Caseback: Sapphire display
- Strap: Brown leather with steel pin buckle
- Price: $1,245
The Jazzmaster Open Heart represents a meaningfully different watch from the Khaki Field. The open-worked dial sections, blue fumé finish, and sapphire display caseback all signal a dressier, more refined piece. As a result, it fits Scanlon’s character: a government official shaped by experience, calculation, and an understanding of systems operating beneath the surface.
Meanwhile, the Nivachron hairspring in the H-10 movement gives the watch enhanced antimagnetic resistance compared to standard automatic calibres. This is a meaningful technical detail at the price point.
How the Two Watches Reflect Their Characters
What makes the Hamilton casting in Disclosure Day interesting is how deliberately the two watches reflect their characters. Hamilton’s own description frames this directly:
The Khaki Field Mechanical signals “clarity, restraint, and purpose.” As a result, it pairs naturally with O’Connor’s whistleblower character driven by conviction. Meanwhile, the watch’s military-inspired simplicity and hand-winding mechanism reinforce the character’s principled approach.
The Jazzmaster Open Heart signals “refined architecture and visible mechanics.” As a result, it pairs with Firth’s government official character shaped by complexity and understanding of hidden systems. Meanwhile, the partially openworked dial reinforces the theme of seeing what lies beneath the surface.
This thoughtful casting is part of what has made Hamilton such a reliable Hollywood partner over the decades. As a result, the watches function as visual storytelling tools rather than just product placement.
Hamilton’s Long Film Legacy
The Disclosure Day casting continues one of the longest brand-Hollywood partnerships in watchmaking. Notable Hamilton film appearances include:
2001: A Space Odyssey (1968) – Hamilton designed the futuristic Pulsar concept watch for Stanley Kubrick’s film, marking one of the earliest examples of a watch brand designing a custom piece for cinema.
Men in Black (1997) – The Hamilton Ventura’s distinctive shield-shaped case became a defining visual element of the Will Smith and Tommy Lee Jones thriller. Our look at the Hamilton watch in Men in Black covers that relationship in more detail.
Interstellar (2014) – The Hamilton Khaki Field Murph was central to the film’s emotional arc, with the watch itself serving as a plot device between Matthew McConaughey’s character and his daughter. Our article on Hamilton announces the Murph watch from Interstellar gives more background on how that reference became one of Hamilton’s most recognizable modern releases.
Indiana Jones and the Dial of Destiny (2023) – Multiple Hamilton references appeared on Harrison Ford’s wrist throughout the film.
As a result, Disclosure Day represents another meaningful chapter in Hamilton’s ongoing relationship with major filmmakers. Steven Spielberg specifically has worked with the brand multiple times across his career, which makes this latest collaboration feel like a natural continuation rather than a new partnership.
How These Watches Compare to Other Hamilton References
The Khaki Field Mechanical 38mm and Jazzmaster Open Heart 40mm cover two distinct segments of Hamilton’s catalog. Below is how they fit within the broader lineup:
Movement: Automatic H-10, 80-hour power reserve
Style: Vintage-inspired field watch with character reference
Price: From $945
Movement: Manual-winding H-50, 80-hour power reserve
Style: Military-inspired tool watch
Price: $725
Movement: Automatic H-10, 80-hour power reserve, Nivachron hairspring
Style: Dress watch with open-worked dial
Price: $1,245
As a result, buyers interested in the Khaki Field aesthetic have multiple Hamilton options. Meanwhile, the Jazzmaster Open Heart fills a distinctly different role as a dressier daily wear piece with mechanical intrigue from the open-worked dial.
Who Should Consider These Watches
Both Disclosure Day watches make sense for different buyer profiles:
The Khaki Field Mechanical 38mm works best for:
- Buyers wanting a first serious Swiss mechanical watch at an accessible price
- Collectors seeking a true military-inspired tool watch
- Smaller-wristed buyers who find 42mm field watches oversized
- Fans of hand-winding movements and minimalist dial designs
The Jazzmaster Open Heart Auto 40mm works best for:
- Buyers wanting a dressier Hamilton with mechanical visibility
- Collectors who appreciate open-worked or skeletonized aesthetics
- Office-appropriate daily wear with subtle character

Final Thoughts on the Disclosure Day Hamiltons
The Disclosure Day watches continue Hamilton’s tradition of thoughtful film casting. Both references are existing catalog pieces rather than limited edition tie-ins. As a result, collectors who watch the film and admire the watches can simply buy them rather than chase a limited release.
For Hamilton, this approach works editorially because the brand’s catalog already includes watches with genuine character variety. The Khaki Field Mechanical and Jazzmaster Open Heart cover two distinct buyer profiles, and the film helps both pieces find new audiences. Meanwhile, the partnership with Steven Spielberg reinforces Hamilton’s standing as Hollywood’s preferred watchmaker.
For collectors building out a Hamilton collection, the Disclosure Day casting provides another reason to consider either reference. The fact that the Khaki Field Mechanical stays under $1,000, while the Jazzmaster Open Heart remains only modestly above that line, helps make Hamilton one of the most accessible entry points into serious Swiss watchmaking with genuine cinematic heritage.
