The name “Hamilton U.S. 66” cannot be verified as a Hamilton watch model or reference in the available official listings. The closest confirmed match is the Jazzmaster Power Reserve Auto, reference H32635131—but there is no evidence connecting it to “U.S. 66.” Hamilton lists that Jazzmaster as a past-collection watch that is not available online.
Is there a Hamilton “U.S. 66” power-reserve watch?
Hamilton’s official material does not identify a watch called “U.S. 66,” and the phrase has no verified explanation in the sources available for this article. It should not be treated as a model name or reference without a product image, original listing, or reference number that confirms it.
The closest official match is the Jazzmaster Power Reserve Auto H32635131. That is a real Hamilton power-reserve model, but its connection to “U.S. 66” remains unverified.
What is the Jazzmaster Power Reserve Auto H32635131?
Hamilton describes H32635131 as an automatic Jazzmaster with an H-13 caliber and a dial-mounted power-reserve indicator. Its principal listed specifications are:

Is H32635131 still available?
Hamilton marks the Jazzmaster Power Reserve Auto as a past-collection model, and its U.S. product page says it is not available online. That does not establish whether a third-party seller has remaining stock. If shopping for it, confirm that a listing names reference H32635131 and verify the seller’s current inventory and return terms; no current marketplace stock or price is established here.

Is this the same watch as the Khaki Field Power Reserve?
No connection between “U.S. 66” and either model is established. Hamilton announced a separate Khaki Field Power Reserve Mechanical 40mm on September 9, 2025. The announcement calls it the first Khaki Field with a power-reserve indicator directly on the dial. It is distinct from the automatic Jazzmaster H32635131, and the cited announcement does not establish a complete specification set for a detailed comparison.
What does the power-reserve indicator tell you?
On the Jazzmaster H32635131, the dial indicator is intended to show the remaining reserve of the H-13 movement. Hamilton specifies up to 80 hours of reserve for this model. The display is a status indicator for the movement, not evidence that the watch will deliver that duration under every condition; the figure is Hamilton’s specification rather than an independent test result.

Does “American watchmaker” describe Hamilton today?
Hamilton has American origins: it was founded in Lancaster, Pennsylvania, in 1892. That history does not mean the current brand manufactures watches in the United States. A historical overview reports that U.S. manufacturing ended in 1969 and operations shifted to Switzerland; see the Hamilton Watch Company overview. It is more precise to call Hamilton an American-origin watch brand than to imply that this is a U.S.-made watch.
