Entrepreneur Bjørn Rune Gjelsten spotted wearing a Rolex

Bjørn Rune Gjelsten, one of Norway's wealthiest entrepreneurs and a serious offshore powerboat racing competitor, was recently spotted wearing a white gold Rolex Cosmograph Daytona reference 116519 — a choice that reads less as a status signal and more as the considered selection of a man who actually uses instruments.

The Rolex Cosmograph Daytona ref. 116519 entered production in the early 2000s as part of Rolex's first generation of Daytona models powered entirely by an in-house movement. The Calibre 4130, introduced with this reference family, replaced the modified Zenith El Primero that had served Rolex since 1988. Rolex engineered the 4130 from scratch: a column-wheel and vertical clutch chronograph beating at 28,800 vph, with a 72-hour power reserve and exceptional reliability. The white gold case measures the standard 40mm, with a tachymetric bezel in matching 18k white gold and a sapphire crystal. Dial variants for the 116519 have included everything from classical black and white configurations to more exotic mother-of-pearl and meteorite options sought by collectors.

The 116519 occupies a distinctive position in the Daytona collector hierarchy. It sits between the steel 116520 — historically the most coveted for its scarcity and waiting lists — and the full precious-metal 116509 in yellow gold. The white gold ref. 116519 offered buyers a cooler, more contemporary aesthetic without the ostentation of yellow gold, and its production run gave it genuine availability compared to the perpetually allocated steel model. Discontinued with the shift to the 126500 series, the 116519 now trades cleanly on the secondary market.

Gjelsten's background makes the Daytona a contextually coherent choice. His offshore racing career places him in a world of split-second timing, mechanical reliability under extreme conditions, and a culture that respects functional precision over decorative excess. The Cosmograph's tachymeter and elapsed-time registers are not decorative on his wrist.

On the grey market, the white gold Rolex Cosmograph Daytona ref. 116519 trades in the range of its original retail, reflecting steady but not speculative collector demand. It remains a quietly distinguished piece for those who know Daytona references beyond the steel trophy models.
