Actor Ashton Kutcher spotted wearing a Rolex

Ashton Kutcher was recently spotted on the wrist with a Rolex Milgauss ref. 116400 in white dial configuration — a technically purposeful choice that reads as quietly confident rather than flashy, which is precisely what makes it worth examining.

Introduced in 2007 as a modern reinterpretation of the original 1956 Milgauss, the ref. 116400 houses Rolex's Calibre 3131, a self-winding movement beating at 28,800 vph with a 48-hour power reserve. Its defining feature is a paramagnetic Parachrom hairspring and a movement architecture shielded by a soft-iron inner cage, allowing the watch to function accurately in electromagnetic environments reaching 1,000 gauss. The case measures 40mm in Oystersteel, fitted with a flat sapphire crystal and screw-down crown offering 100 metres of water resistance. The white dial variant of the 116400 presents a clean, high-contrast reading surface with applied hour markers, paired with the model's signature orange lightning-bolt seconds hand — a detail that nods directly to the original reference 6541.

From a collector standpoint, the Milgauss ref. 116400 occupies an interesting position. It has historically traded below its more celebrated sibling references — the Submariner, Daytona, GMT-Master — yet it carries genuine engineering heritage and is increasingly appreciated by collectors who prioritize mechanical purpose over social cachet. The white dial version, alongside the discontinued GV (green-crystal) variant, tends to hold secondary market value more robustly than the all-black configuration. Rolex discontinued the entire Milgauss line in 2023, which has quietly pushed grey-market prices upward as new old stock dries up.

Ashton Kutcher is no casual watch wearer. As a prominent tech investor through his A-Grade Investments fund — with early stakes in companies like Airbnb and Uber — Kutcher occupies a world where understated horological choices carry weight. The Milgauss, with its scientific pedigree and anti-establishment Rolex positioning, fits that profile precisely.

With the ref. 116400 now discontinued, grey-market pricing has firmed appreciably. The white dial variant represents a sound entry point into a closed-chapter Rolex reference with a story that resonates well beyond the dial.
