History
Genesis of the Concept
The late 1970s marked a period of experimentation for Patek Philippe, as the company sought to push the boundaries of traditional watchmaking. The idea of a single watch that could simultaneously display all 24 time zones was born from the need for a tool for businessmen, diplomats, and globe‑trotters. The result was the prototype Patek Philippe 4000, which first appeared in 1979 during the Paris Watch Fair.

Evolution of the Model Series
- 4000 Series (1979–1990): The original Worldtimer featured a 24‑hour dial with a rotating bezel and a hand that could be set to any of the 24 time zones. The case was a 42 mm steel capsule, and the movement was the self‑winding Calibre 2405.
- 6000 Series (1990–2000): Patek refined the design, introducing a more refined dial layout, improved case materials (steel and gold options), and a new movement, the Calibre 2405A, which offered enhanced power reserve and a slimmer profile.
- 7000 Series (2000–2010): This iteration saw the introduction of the Calibre 2405B, a further refinement with a higher beat rate (28,800 vibrations per hour) and a more robust escapement. The case size increased to 44 mm, and the watch became available in white gold and rose gold.
- 2000 Series (2010–Present): The modern Worldtimer, often referred to as the Worldtimer 2000, incorporates the Calibre 2405C, a self‑winding movement with a 60‑hour power reserve and a 28,800 vph beat rate. The dial now features a 24‑hour indicator, a perpetual calendar, and a date window. Patek also introduced a limited edition with a sapphire bezel and a 3‑piece case for the 24‑hour display.
Throughout its evolution, the Worldtimer has maintained its core principle: a single watch that can be adjusted to any of the world’s time zones, making it a timeless tool for the modern nomad.

Gear Train and Time Zone Setting
The gear train is a marvel of engineering. It consists of the following stages:
- First stage: 24‑hour gear that drives the hour hand and the 24‑hour indicator.
- Second stage: 12‑hour gear that drives the minute hand.
- Third stage: 60‑minute gear that drives the second hand.
To adjust the time zone, the wearer rotates the crown, which engages a set of micro‑gears that shift the 24‑hour indicator by one hour increments. This mechanism is engineered for smooth operation and minimal wear, ensuring longevity.

Power Reserve and Accuracy
The 60‑hour power reserve allows the watch to run for almost a week on a single winding, a feature that is particularly valuable for frequent travelers. Accuracy is maintained at ±5 seconds per day, thanks to the high beat rate and the use of a gold‑alloy balance spring, which provides stability against temperature variations.
Maintenance and Service
Patek Philippe recommends servicing the Worldtimer every 10 years or after 600 hours of operation, whichever comes first. During a service, the movement is disassembled, cleaned, lubricated, and reassembled with precision. The company’s service centers are located in Geneva, ensuring that each watch receives the highest level of care.
