Watch Paparazzi

Entrepreneur Anant Ambani spotted wearing Patek Philippe

Anant Ambani, the youngest son of Reliance Industries chairman Mukesh Ambani, has been spotted wearing what many serious collectors consider the single most complicated wristwatch in regular production: the Patek Philippe Grand Complications reference 6300G-010, an 18-carat white gold behemoth retailing in the vicinity of $9 million and limited to a global edition of precisely seven pieces.

The Patek Philippe 6300G-010 traces its DNA to the Calibre 89 pocket watch unveiled in 1989 to celebrate the manufacture's 150th anniversary — itself long regarded as the most complicated portable timepiece ever made. The 6300G is its spiritual successor in wristwatch form, housing the hand-wound Cal. GS 36-750 QIS FUS IRM movement, which comprises 1,366 components across 20 complications. Those complications include a minute repeater, perpetual calendar, tourbillon, equation of time, and a sky chart, but the genuine horological headlines belong to two patented world firsts: an acoustic alarm that strikes the programmed time on demand, and a harmonious striking mechanism that prevents two chiming functions from sounding simultaneously. The 48mm case in 18-carat white gold is entirely hand-engraved — a process requiring hundreds of hours from a single craftsman — finished with a blue opaline dial that frames the complexity beneath with almost theatrical restraint.

For collectors, the reference 6300G-010 occupies a category largely unto itself. Seven examples is not a marketing figure; it reflects the genuine manufacturing constraint of producing a movement of this density to Patek's tolerances. Each piece is effectively bespoke in terms of the time invested, and provenance is everything — the seven owners are almost certainly known to the manufacture.

Anant Ambani's appearance with the 6300G-010 is consistent with a collecting approach that prioritises technical significance over visibility. His family's relationship with ultra-high horology is well documented, and this sighting adds a meaningful data point: the 6300G-010 is not a watch purchased for a public occasion; it is worn by someone who understands precisely what is on his wrist.

With no secondary market comparables to speak of — seven pieces simply do not circulate — grey market pricing is theoretical at best, though auction estimates for comparable grand complications from Geneva have repeatedly exceeded the $9 million retail figure, suggesting the 6300G-010 would command a significant premium if one ever surfaced publicly.
