Youtuber Olajide JJ Olatunji KSI spotted wearing Rolex

KSI — born Olajide JJ Olatunji and boasting over 24 million YouTube subscribers — was recently photographed wearing what is unquestionably one of the most extravagant references in the current Rolex lineup: the Pearlmaster 39 in 18KT white gold, reference 86409RBR, set entirely with factory diamonds.

The Pearlmaster 39 ref. 86409RBR is built on Rolex's in-house Calibre 3235, a self-winding movement beating at 28,800 vph with a 70-hour power reserve, featuring the Chronergy escapement and Parachrom hairspring. The case measures 39mm in 18KT white gold, paired with the exclusive Pearlmaster bracelet — a five-piece link design that Rolex introduced specifically for the Pearlmaster family in 1992 and which remains unavailable on any other Rolex collection. The 'RBR' suffix in the reference denotes a full factory brilliant-cut diamond set, covering the bezel, dial, and bracelet in Rolex-certified stones, graded and set in Geneva.

The Pearlmaster occupies a deliberate niche within Rolex's portfolio: it is the house's high jewellery line, positioned above even the Day-Date in terms of gem-setting ambition. Collectors and the trade treat factory diamond references with particular seriousness — Rolex's in-house setting work is meticulous, and the RBR designation guarantees continuity of origin that aftermarket stone-setting simply cannot replicate. The 86409RBR consequently holds its value with unusual tenacity on the secondary market.

KSI has built one of the most diversified brands in digital media, spanning music, boxing, and the Prime energy drink empire he co-founded with Logan Paul. His public profile increasingly mirrors that of a mainstream celebrity rather than a YouTube creator, and his watch choices have reflected that trajectory — the Pearlmaster Datejust 39 ref. 86409RBR is not a watch purchased to signal casual wealth; it is a deliberate acquisition from Rolex's most rarefied shelf.

At a UK list price of approximately £160,000, the Rolex Pearlmaster 39 ref. 86409RBR translates to roughly $200,000 USD at current retail. Grey-market premiums on fully set white gold Pearlmaster references are comparatively modest given their niche demand profile, but clean examples with box and papers rarely trade below retail, frequently trading at or modestly above it.
