Youtuber Olajide JJ Olatunji KSI spotted wearing a Patek Philippe

During the production of a music video, Olajide 'KSI' Olatunji was caught on camera wearing two watches that together represent opposite poles of contemporary collector culture. On one wrist, the Patek Philippe Annual Calendar 5147G — arguably the more quietly significant of the two — demonstrated that the British YouTube star and professional boxer is operating well beyond impulse luxury purchases.

The Patek Philippe 5147G is powered by calibre 324 S QA LU, a self-winding movement measuring 27.50mm in diameter and beating at 28,800 vph. It offers annual calendar with separate date, day, and month displays — the latter advancing automatically through months of 30 and 31 days — plus a moon-phase display accurate to one day's deviation per 122 years. The 18k white gold case measures 38.5mm and, in the 5147G configuration with factory-set diamond bezel, bridges the gap between Patek's dressy Calatrava line and its complication-focused catalogue. Introduced in the mid-2000s as an evolution of the 5146, the reference has remained in production long enough to establish genuine secondary-market depth.

Among collectors, the 5147G occupies a considered position. The Annual Calendar complication — patented by Patek Philippe in 1996 — remains proprietary to the maison, lending the reference an exclusivity that goes beyond its jewellery presentation. The 62-diamond bezel adds desirability in certain markets without cannibalising the movement's credibility, which is the risk less accomplished manufactures run with heavily set pieces. Serious buyers recognise calibre 324 S QA LU as the same base movement found across much of Patek's self-winding complication range.

KSI's choice to wear the 5147G in a professional production context — rather than a red carpet or a ringside appearance — suggests the piece functions as everyday wearing stock for him. At 29 years old and with a media and boxing empire that has generated nine-figure revenues, the demographic profile fits an emerging generation of ultra-high-net-worth collectors who arrived at Patek through culture rather than inheritance.

At UK retail the 5147G with diamond bezel listed at approximately £39,590, translating to roughly $49,000 USD at time of listing. On the grey market, factory-set diamond-bezel variants of the 5147G have traded between $55,000 and $70,000 depending on condition and box-and-papers completeness — a modest but consistent premium that reflects stable long-term demand for white gold Annual Calendar references.
