Footballer Cristiano Ronaldo spotted wearing a Jacob & Co

Cristiano Ronaldo appeared at a high-profile formal event — consistent with his Real Madrid era appearances on the Monaco social circuit — wearing one of the most aggressively gem-set timepieces in contemporary watchmaking: the Jacob & Co Grand Baguette Five Time Zone in 18K white gold, completely encrusted in baguette and round brilliant-cut diamonds.

The Grand Baguette is Jacob & Co's most extreme expression of the multi-time-zone complication the brand built its reputation on. The case, constructed in 18K white gold, is entirely pavé-set with baguette-cut diamonds — including the bezel, case sides, crown, and lugs. The dial itself features five individual sub-dials, each displaying a different world time zone labeled New York, Paris, Tokyo, and two further cities, with blue steel hands providing the only contrasting color element against the diamond field. A large central round brilliant diamond sits at the intersection of the sub-dial layout, functioning as both a decorative anchor and a structural visual cue. The watch runs on a proprietary Jacob & Co quartz movement, prioritising gem surface area over mechanical complexity — a deliberate and defensible choice at this price point.

The Grand Baguette occupies a specific and somewhat polarising space in collector culture. It is not a movement story; it is an object of applied jewellery art, closer in taxonomy to a Graff or a Chopard Red Carpet piece than to a complications watch. The total diamond weight across the case and dial runs to well over 15 carats in most full-pavé configurations, and production numbers are extremely limited — often single-digit annual outputs per configuration.

Ronaldo has long demonstrated a preference for Jacob & Co references that read loudly and unmistakably as luxury objects. His collection has included multiple Jacob & Co pieces over the years, and the Grand Baguette is the brand's ultimate statement — a watch that functions as portable wealth display with few peers.

On the secondary market, full-diamond Grand Baguette examples in white gold rarely surface, and when they do, prices align closely with or exceed original retail. At an original UK list of £1.5 million — approximately $1.9 million at prevailing rates — this remains one of the ten most expensive wristwatches regularly worn by active athletes anywhere in the world.
