Case material: Yellow gold; Charge: Automatic; Conditions: Used Presentation condition : With dealer guarantee ; Model: Complications World Time Price on request Gmtbroker Reference: 5130J-001 Latest Larger Model...Patek Philippe 5130J-001 World Time 18kt Yellow Gold The Patek Philippe World Time (ref. 5130J) features a mechanical automatic movement; 24 time zone indication; and 39.5mm, Yellow Gold case on a Brown alligator strap with a deployant clasp. The 5130J is a throwback to an earlier era. The unique ring shaped hour hand is drawn from the original Patek World Time watches from the 1930's and gives the piece a wonderful vintage feel. A larger case size (now 39.5mm, as opposed to 37mm on the older model) adds improved legibility, and the elegant, hand-guillochéd center makes this model a horological work of art. The local time indicated by the hour and minute hands applies to the location on the city disk that is directly aligned with 12 o’clock. The crown is used to set the correct time in conjunction with the 24-hour ring, so a distinction can be made between 4 am and 4 pm. Now, switching from one time zone to another is accomplished simply by pressing the button at 10 o’clock. Every time it is pressed, the hour hand will advance by one hour while the city ring and the 24-hour ring will rotate counter-clockwise by one hour(equivalent to one time zone). Pressing the button 24 times emulates a trip around the world and a return to thepoint of departure. Patek Philippe’s World Time watches belong to the category of  complications.
