Patek Philippe 5110P World Time Platinum 950, Blue Guilloche "Décor Guilloche" Dial, 24-hour and Day/Night Indication for the 24 Time Zones, Automatic, Sapphire Crystal Exhibition Case Back, Black Alligator Leather Strap with Platinum Fold-Over Deployant Buckle, 37mm - This self-winding, World Time 5110 will tell the hour in 24 cities and it can be adjusted to show a new local time while not affecting the minutes. The philosophy behind this watch, which was brought out during the early 2000’s, was to make an international statement of harmony. It was made in 18K white, rose or yellow gold, and platinum, with a two-part case and a screwed down transparent caseback. It’s 10mm thin; the crown is protected and the push-bar on the band at 10 o’clock changes the settable discs of the time zones. The inner face is Bleu Guilloche with white indexes, inside an outer and revolving disc, marking both the nocturnal and diurnal hours. It has white gold lozenge hands; the dial, case, and movement are all signed.

The dynamic Calibre 240 movement has 33 jewels, a straight-line lever escapement, a 22K gold microrotor, a Gyromax balance with a shock absorber and a self-compensating free-sprung flat balance spring. The rhodium-plated mechanism has fausses cotes decoration and it’s stamped with quality mark of the Seal of Geneva. The crocodile leather bracelet has a white gold deployment clasp and it’s water-resistant to 2.5 atmospheres. It was discontinued, and is considered rare – truly one of the greatest international wristwatches of all time.

So much rarer and more precious than gold... only 160 tons of platinum is extracted annually, compared to 1,500 tons of gold mined. This is one reason collectors are eager to secure these solid platinum World Time Platinum Complications, that are no longer available and completely sold out from Patek Philippe.

The Patek Philippe 5110P World Time in solid 950 platinum is a masterclass in haute horlogerie and global sophistication. Revered for its elegance and mechanical ingenuity, this 37mm timepiece features a striking blue guilloché “Décor Guilloché” dial, intricately patterned to reflect light with mesmerizing depth. Surrounding the inner dial are two rotating discs that display 24 cities and a 24-hour day/night scale, enabling the wearer to instantly read the time across the globe—an exceptional complication designed for the true world traveler. At 10 o’clock, a discreet pusher allows seamless adjustment of time zones without disturbing the running minutes, showcasing Patek Philippe’s unparalleled command of mechanical precision.

Housed in a slim, refined case only 10mm thick, the 5110P is powered by the legendary Caliber 240 HU—an ultra-thin, self-winding movement featuring a 22K gold micro-rotor, a Gyromax balance, and Geneva Seal certification, all visible through the sapphire crystal exhibition case back. The platinum case is paired with a luxurious black alligator leather strap and secured with a platinum fold-over deployant clasp, exuding understated power and prestige.

Discontinued and no longer in production, the 5110P remains one of the most sought-after World Time references ever made by Patek Philippe. Its platinum construction adds a level of rarity that far surpasses gold, with less than one-tenth the annual global production—making this timepiece an even more coveted treasure among collectors. A watch of this caliber is not just an instrument of time; it is an heirloom of global distinction and timeless excellence.
