Television presenter Robert Irwin spotted wearing a Omega

Television presenter and wildlife photographer Robert Irwin was recently photographed wearing an Omega Speedmaster Professional Ref. 3570.50.00, a chronograph renowned for its heritage and technical precision. The sighting captures Irwin in a casual beige jacket paired with jeans, his wrist displaying the distinctive black dial and polished stainless steel bracelet of this iconic Swiss instrument.

The Omega Speedmaster Professional 3570.50.00, introduced in 1997, represents a significant evolution of the Speedmaster line. It houses the calibre 1861, a hand-wound mechanical movement with a 48-month power reserve and column-wheel chronograph mechanism. The case measures 42mm in diameter and features a hesalite acrylic crystal—a choice that maintains authenticity to the original 1957 design. The dial employs a lacquer finish, creating depth and contrast across the matte black surface. Three white subdials record elapsed hours, minutes, and seconds, while the fixed tachymetre scale on the bezel enables calculation of speed over a known distance. Water resistance stands at 50 metres, adequate for splash protection but not diving.

The 3570.50.00 earned its reputation through NASA qualification for extravehicular activity (EVA) and moon missions, cementing its status among serious collectors. The lacquer dial variant offers aesthetic refinement compared to earlier printed versions, and the 42mm case represents the modern professional standard. Production of this reference continued through the early 2000s, making it available on the secondary market with relative frequency compared to vintage models.

Irwin's choice reflects the Speedmaster's role as a working chronograph rather than purely ornamental timepiece. For wildlife photographers, the robust construction and legible dial provide practical utility alongside horological credibility. The pairing of the Speedmaster with Irwin's profession—documentation and precision in natural environments—underscores why this watch transcends celebrity endorsement and remains trusted by professionals.

Retail pricing for the Speedmaster Professional 3570.50.00 originally sat around $4,500–$5,000 USD at launch. On the pre-owned market, examples in good condition trade between $5,200 and $6,500 depending on dial condition and service history. The lacquer dial variant commands a modest premium over printed versions, reflecting collector preference for depth and finish quality.
