Actor William Holden spotted wearing a Jaeger LeCoultre

William Holden, one of Hollywood's most bankable leading men, wore a Jaeger-LeCoultre Triple Date Moonphase Ref. E866 in this restored 1957 portrait with Italian cinema icon Sophia Loren. The high-resolution image, recently recirculated on social media, reveals the watch worn on a leather strap—a candid documentation of practical luxury that defined the era's approach to fine timepieces on set and off.

The Ref. E866 is a sector-dial triple date moonphase, a design hallmark of Jaeger-LeCoultre's mid-century complications portfolio. The movement is a manual-wind calibre featuring a 30-day moonphase aperture at 12 o'clock, with day-of-week, date, and month windows arranged across the lower two-thirds of the dial. The case measures approximately 35–36 mm in diameter, typical of dress watches from this period, and sits in yellow or rose gold—both materials visible in period examples. Water resistance is modest by modern standards, rated at 30 meters, reflecting its intended purpose as a formal wristwatch rather than a tool. The calibre operates at 18,000 vph (2.5 Hz) and achieves approximately 40 hours of power reserve. Production of the E866 spanned the early to mid-1950s through the early 1960s.

The E866 remains highly sought by vintage collectors for its elegant integration of complications and its accessible size relative to contemporary dress watches. Unlike the later, larger Ref. P456, which replaced this model, the E866's sector dial layout was distinctly modern for its time and has become a template admired in contemporary JLC revivals. Yellow-gold examples command premiums over rose-gold variants, particularly those retaining original dials with applied indices and intact moonphase discs.

Holden's choice of the E866 reflects the Hollywood actor's sophisticated taste in horology—a watch that balanced technical achievement with understated elegance, worn not as a statement but as a trusted instrument. The pairing with Loren in this archival photograph has added cultural weight to the reference, particularly as Jaeger-LeCoultre has reintroduced triple date moonphase designs in its modern Classique range, inviting contemporary collectors to revisit this mid-century aesthetic.

Vintage Ref. E866 examples in good condition now trade between $8,000 and $14,000 USD on the secondary market, depending on case material, dial condition, and movement service history. Original examples with intact moonphase mechanisms and unpolished cases command the strongest prices, while dial refinishes and case work reduce value considerably. The reference's accessibility relative to vintage Patek Philippe or Vacheron Constantin complications, combined with its cultural cachet through Hollywood provenance, ensures steady collector demand.
