PATEK PHILIPPE WORLD TIME 18K WHITE GOLD / 5110G

MODEL: 5110G

18K white gold with diameter of 36mm. Sapphire crystals front and display back. Button at 10 o'clock advances the hour hand in one hour increments. This allows the traveler the ability to change the time as he or she travels through time zones.

Dial is silver. Inner zone is guilloche with hour markers. Surrounding this area is a ring with numerals '1' through '24' which represent the 24 hours in a day. This ring turns counter clockwise, making a full rotation once every 24 hours. The time in the 24 reference cities, printed in the dial's outermost area, can be seen simultaneously with this world time system. In my opinion, this manner of tracking world time is much better than watches which merely use a 24 hour "GMT" hand, forcing the wearer to calculate world time versus simply reading it at a glance as this watch allows.

Movement is the Patek Philippe Caliber 240 HU with 33 jewels and 48 hour power reserve. The caliber is stamped with the Geneva Seal. Original black hand sewn crocodile with 18k white gold Patek deployant clasp. Watch is sealed up by agent since 2011, with service paper.........and cert.
