Both watches in Disclosure Day are Hamiltons, and both are ordinary catalogue models you can walk in and buy: the Khaki Field Mechanical 38mm at $745 (ref H69409930) and the Jazzmaster Open Heart Auto 40mm at $1,245 (ref H32675540). No limited edition, no waiting list, no resale premium. Hamilton has a dedicated page for the film, which makes this one of the very few screen-watch identifications that comes straight from the brand rather than from freeze-frames.
That is unusual enough to be the point of this page. Below: which character wears which, what you are actually getting for the money, and why the other Hamilton film watch of 2026 — the one tied to Nolan's Odyssey — is a completely different proposition that a lot of coverage is confusing with this one.
The two watches
| Watch | Reference | Price | Worn by |
|---|---|---|---|
| Khaki Field Mechanical 38mm | H69409930 | $745 | Daniel Kellner |
| Jazzmaster Open Heart Auto 40mm | H32675540 | $1,245 | Noah Scanlon |
Both are confirmed on Hamilton's own Disclosure Day page — brand-primary, not a spotter's guess. Both are standard production models, in stock at the time of writing.
For context on why this film's watches are being searched at all: Spielberg's Disclosure Day opened in June 2026 to $44M domestic and $92.9M worldwide, his biggest-ever opening for an original film.
The $745 one: Khaki Field Mechanical
This is the watch most people are actually here for, and it is a genuinely good recommendation independent of the film.
The Khaki Field Mechanical is Hamilton's reissue of the field watches it made for the US military — hand-wound, no automatic rotor, 38mm, matte case, high-legibility dial. You wind it every morning. Some people find that irritating; others find it the entire appeal.
What you are paying for at $745: a Swiss mechanical movement in a watch that is deliberately plain. There is no date window, no crown guards, no polish. It is a design that has not needed changing since the 1940s, which is why it appears in films set in any decade.
What you are not paying for: thickness, water resistance for diving, or a bracelet — it ships on a strap.
The case size matters more than the price here. 38mm is small by modern standards and correct for the design. Hamilton also makes this in 42mm; if you have never worn a field watch, the 38 is the one that looks right, and it is the one on screen.
The $1,245 one: Jazzmaster Open Heart
A completely different object. "Open heart" means a cut-out in the dial exposing the balance wheel, so you watch the movement beating. It is automatic — self-winding from wrist motion, no daily ritual — 40mm, dressier, on a leather strap.
This is the watch of the character who wants to be seen as substantial. That is not us reading into it: the two watches are doing visibly different jobs, and putting the plain hand-wound field watch on one man and the exposed-movement dress automatic on the other is the kind of costume decision that does character work without dialogue.
Honest assessment: open-heart dials divide people. Some find the exposed balance wheel mesmerising; others find it a gimmick that ruins an otherwise clean dial. Look at it in person before spending $1,245 — this is not a design you can evaluate from a product photo.
The other Hamilton film watch of 2026 — and the trap
Search for Hamilton and film in 2026 and you will hit the Khaki Field Auto "The Odyssey" Limited Edition (ref H70675530), a bronze 42mm made for Nolan's Odyssey, released the same day as the film. $1,495, or CHF 1,195, limited to 2,112 pieces.
Two things you should know before buying one:
It never appears in the film. Hamilton says so themselves. Unlike the Interstellar, Tenet and Oppenheimer watches — which were actual props — this is a collectible inspired by the film. If your reason for buying is "I want the watch from the movie," this is not that watch.
Retail is likely gone. It has been trading around $3,634 on Chrono24 against a $1,495 list, which tells you the limited run cleared. You would be buying at more than double retail, for a watch that was never on screen.
By contrast, the two Disclosure Day watches are unlimited, at list, and genuinely in the film. That is the whole comparison.
Why Hamilton keeps turning up in films
There is a reason this brand appears in more movies than any other watchmaker, and it is not luck. Hamilton has a dedicated entertainment division that has been placing watches in productions since the 1950s — Strangelove, Men in Black, Interstellar, Tenet, Oppenheimer. The company even keeps an in-house archive of the pieces it has supplied.
That history is why a Hamilton film watch is usually easy to verify: the brand publishes it. Compare that with almost everything else in this category, where identification depends on someone pausing a frame and matching a bezel. When a brand tells you directly, take it — those are the pages worth writing.
If $745 is more than you want to spend
The field-watch design is one of the most widely copied in the industry, which works in your favour.
- Timex Expedition North Field Post Solar, around $209. Solar so you never wind it or replace a battery, 100m water resistance, the same clean field layout. It is the practical answer rather than a compromise — for a watch you wear to work, arguably the better object.
- Seiko 5 Sports field models, roughly $200–$300. Automatic, and Seiko's finishing at that price is hard to fault.
- The used market. Hamilton Khaki Fields turn up constantly secondhand because people buy them, wear them twice and move on. Expect meaningful savings on a watch that is difficult to damage.
What we would not do is buy a fashion-brand quartz "field watch" at $150 to get the look. The whole point of this design is that the mechanism is honest and the dial is legible. A quartz movement in a homage case gets you the shape and none of the reason.
Is a hand-wound watch annoying?
Worth answering plainly, because it is the real question behind the $745 purchase.
You wind it once a day, roughly twenty turns of the crown, which takes about ten seconds. If you wear it daily it becomes automatic in the habitual sense. If you rotate between watches it will be stopped every time you pick it up, and you will need to reset the time.
So: excellent as a daily watch, mildly annoying as one of several. That is the honest test, and it has nothing to do with the film.
FAQ
What watch is worn in Disclosure Day? Two Hamiltons. The Khaki Field Mechanical 38mm (ref H69409930, $745) and the Jazzmaster Open Heart Auto 40mm (ref H32675540, $1,245). Both are confirmed on Hamilton's own website.
Can I still buy them? Yes. Both are standard catalogue models, not limited editions, and were in stock at the time of writing.
Is the Khaki Field Mechanical automatic? No — it is hand-wound. You wind it daily. Hamilton makes automatic Khaki Fields too, but the one in the film is the manual version.
Is the Hamilton Odyssey watch in the film? No. Hamilton confirms the Odyssey limited edition never appears on screen — it is a collectible inspired by the film, unlike their Interstellar and Oppenheimer props. It is also trading well above its $1,495 list price.
What size is the watch on screen? 38mm. Hamilton also sells a 42mm version of the same design; the smaller one is what appears and is the more period-correct proportion.
What is a good cheaper alternative? The Timex Expedition North Field Post Solar at around $209 — solar-powered, 100m water resistant, the same field layout, and no winding.
What does "open heart" mean? A cut-out in the dial that exposes the balance wheel so you can watch the movement running. It is a design choice that people either love or find distracting — see it in person first.
Are these watches good value? The Khaki Field Mechanical at $745 is widely considered one of the better Swiss mechanical watches under $1,000, film or no film. The Jazzmaster at $1,245 depends entirely on whether the open-heart dial appeals to you.
