Actor John Krasinski spotted wearing a Hamilton

On the wrist of CIA analyst Jack Ryan in Amazon's political action series Tom Clancy's Jack Ryan, John Krasinski wears the Hamilton Khaki Field Auto Chrono in black PVD-coated stainless steel, reference H71626735 — a detail sharp-eyed viewers and the show's costume department clearly thought through together.
The H71626735 is powered by Hamilton's Calibre H-21, an automatic column-wheel chronograph movement with a 60-hour power reserve. The black PVD case measures 42mm and pairs with a ceramic tachymeter bezel, black dial with luminous applied indices, and a practical rubber strap. It is water-resistant to 100 metres. For a movement that offers genuine column-wheel architecture at this price tier, the H-21 remains one of the more honest value propositions in the category — column-wheel construction typically commands a significant premium elsewhere.
The Khaki Field line traces its roots to Hamilton's long history supplying military-grade timepieces to the U.S. armed forces, beginning in earnest during World War II. That heritage is not merely marketing shorthand: Hamilton's mil-spec DNA gave the Khaki Field a legitimacy that other tool-watch homages often lack. The Auto Chrono variant extends that tradition into a more capable complications package without abandoning the field-watch legibility that defines the family.
For a character defined by his Marine Corps background and no-nonsense analytical temperament, the H71626735 is a credible on-screen choice. It reads as functional rather than showy — exactly what Jack Ryan would wear. Krasinski himself has a track record of understated watch choices on and off camera, and the Khaki Field fits that pattern cleanly.
On the market, the Hamilton Khaki Field Auto Chrono H71626735 retails at approximately $1,995, and grey-market prices hover close to that figure, reflecting steady rather than speculative demand. It is not a watch that flips for profit, but among tool-watch enthusiasts it holds a consistent reputation for delivering mechanical substance without the inflated premium attached to more prominent nameplate. Screen exposure of this kind rarely hurts.
