Gerald Charles Unveils Its Most Complex Timepiece, The Masterlink Perpetual Calendar

Gerald Charles, the independent Swiss watchmaking Maison founded by the great Mr. Gérald Charles Genta, unveils its most complicated watch since its reestablishment less than a decade ago. The Masterlink Perpetual Calendar, developed entirely in-house, marks a new chapter for the young and ambitious Maison as it continues to expand its repertoire of poetic complications.

In keeping with Gerald Charles’s “No Compromise” watchmaking philosophy, established by Mr. Genta more than a quarter of a century ago, the Masterlink Perpetual Calendar introduces an in-house, asymmetrical, automatic perpetual calendar calibre with a three-counter display.

Longitude

Longitude is the angular distance of a specific location on Earth, measured east or west from the Prime Meridian. The Prime Meridian, located at 0 degrees longitude, serves as a reference point from which longitude lines are measured. Longitude lines extend from 180 degrees west to 180 degrees east, forming a complete circle around the Earth.

Longitude plays a crucial role in determining the location between east and west and is used in conjunction with latitude to create accurate geographic coordinates. Measuring longitude is essential for navigation, timekeeping, and precise location determination on maps and Global Positioning Systems (GPS).

Longitude lines also play a significant role in certain watch features that rely on geographic data, such as world time complications or sunrise/sunset indicators.
