The world on the wrist
greubel forsey gmt 01 - Greubel Forsey

This timepiece marks a first, in more than one respect, for both Greubel Forsey and the history of GMT watches. After exploring the world of the tourbillon throughout the 2000s, and inventing, developing and increasing innovations at their company, Robert Greubel and Stephen Forsey have now combined it with a second complication, which they have naturally interpreted in their own way.

True to their philosophy and their traditional approach, they were not content with the traditional display of a time zone by the jumping hour in an aperture or by a hand. They thus offer, as a bonus and as a first, a three-dimensional expression of time zones in the form of a globe that makes a full rotation in 24 hours, counter-clockwise.

For more visual details and an observation of the southern hemisphere, a lateral window built into the case offers an equatorial view of the earth in rotation. Spatially, everything is perfectly balanced, with a striking sense of depth offered by the globe, singularly clear, and by the Tourbillon 24 Secondes.

The GMT calibre features the 25° inclined Tourbillon 24 Secondes cage, one of Greubel Forsey’s major patented inventions. In addition to its chronometric virtues and reliability, it was chosen for its compact size. One of the challenges of the Watchmaking Inventors was to provide displays that are clear and useful, without overdoing it, and to thereby simplify use of the timepiece.
