Actor Kan Kantathavorn spotted wearing a Patek Philippe

Thai actor and TV presenter Kan Kantathavorn recently surfaced on social media wearing a timepiece that would stop any serious collector mid-scroll: the Patek Philippe 5971P, one of the most coveted jewellery complications in the Geneva manufacture's modern catalogue.

The 5971P houses Caliber CHR 27-70 Q, a manually wound movement measuring 27.5mm in diameter and 7.2mm thick. It delivers a perpetual calendar displaying date, day, month, four-digit year, and leap-year indication, alongside a mono-pusher split-seconds chronograph and a moon-phase display accurate to one day's deviation every 122 years. The 40mm platinum case provides ideal proportions for a complication of this density, and Patek chose the metal deliberately — platinum's cool, grey lustre amplifies the contrast with the deep black dial without the ostentation of yellow or rose gold.

What distinguishes this reference from the broader 5970 family — its immediate predecessor — is the jewellery execution. The bezel carries 42 baguette-cut diamonds set in a continuous, blade-thin channel, while the dial deploys six princess-cut and one baguette-cut diamonds as hour markers. The result is a watch that operates simultaneously as a grand complication and a significant piece of gem-set jewellery, a combination Patek has historically reserved for its most exclusive clientele. The 5971P was produced in limited numbers before being succeeded by the 5271P, and examples surface infrequently on the secondary market.

Kan Kantathavorn, widely known across Thailand for his television and acting work, has demonstrated a consistent appreciation for serious horology. Choosing the 5971P over more commercially visible references signals genuine engagement with the Patek catalogue rather than badge-driven purchasing — this is not a watch one stumbles into.

On the grey market, the 5971P in platinum has traded well above six figures, with recent transactions circling the $450,000 mark depending on condition, box, and papers. No official retail price exists today as the reference is discontinued, which only intensifies demand among collectors who recognise perpetual calendar chronographs of this pedigree as genuinely finite assets.
