Actor Diego Calva spotted wearing a Omega

Diego Calva stepped onto the red carpet in a sharp navy pinstripe three-piece suit anchored by a flower boutonnière and a black tie — and on his wrist, the horological cherry on top: an Omega Speedmaster Professional Moonwatch in 18K Moonshine Gold. It is the kind of watch choice that reads as deliberate rather than coincidental, a serious collector's statement disguised as evening-wear glamour.

Omega introduced its proprietary Moonshine Gold alloy — a paler, more fade-resistant variant of traditional rose gold — with the 2021 Speedmaster Professional Moonwatch reference 310.60.42.50.01.001. The 42mm case pairs the warm champagne tone of Moonshine Gold with a black ceramic tachymètre bezel and a deep black dial finished with applied Moonshine Gold indices and baton hands. The matching integrated bracelet completes the monolithic silhouette. Powering it all is the calibre 3861, a hand-wound movement that earned the coveted Master Chronometer certification from METAS, guaranteeing accuracy to within 0/+5 seconds per day even in magnetic fields up to 15,000 gauss.

From a collector's standpoint, this reference occupies genuinely rarefied territory. It is not a limited edition in the traditional numbered sense, yet its solid-gold construction and Moonshine alloy exclusivity place it firmly outside the reach of the standard Speedmaster collector. The movement upgrade to 3861 — the direct descendant of the cal. 321 that went to the Moon — gives it historical legitimacy beyond its precious-metal flash. Anti-reflective sapphire replaces the hesalite crystal of the classic steel variant, a concession to wearability that purists debate but most owners welcome.

Calva has emerged as one of Hollywood's most-watched young talents following his lead role in Damien Chazelle's Babylon (2022). His watch choices reflect a considered aesthetic — rich but not ostentatious, historically grounded. The Moonshine Speedmaster Professional is exactly that: an object with a 65-year racing and space heritage dressed in precious metal without abandoning its mechanical soul.

At retail, the Omega Speedmaster Professional Moonwatch 310.60.42.50.01.001 lists at approximately $43,600 USD. On the secondary market, demand for solid-gold Speedmaster references has remained robust, with grey-market prices tracking closely to retail — a sign of genuine desirability rather than speculative flipping.
