With an asymmetric case featuring a three-dimensional globe presented in a multi-layered dial configuration, the Greubel Forsey GMT has planted a flag in the competitive world of horology.

The dial is impressive and is an attraction alone in various ways. Starting above, the 12 O’clock position features the main dial where the local time is starred with an off-set small seconds counter located in between the 2 and 5 O’clock position of the local time display. Moving down clockwise, a power reserve indicator of up to 72 hours is presented in retrograde style sitting right below the small seconds counter. Shifting down, the signature organ of the watch is featured, a tourbillon regulator with a 25-degree inclination with an incredibly high speed of one rotation per 24 seconds, whilst most tourbillons rotate once per minute. Sliding over to the left, an obvious attraction and a defining characteristic of the GMT is displayed, the globe. Presented with a 24-hour ring interpreting the time in correspondence to the appropriate location, the three-dimensional globe mimics the actual rotation of the globe to a scale of approximately 1/980million, it is a profoundly impressive way to translate the various time zones of the world. Lastly on the dial side, an additional subsidiary dial sitting right above the globe displays the second time zone.

Flipping to the movement side of the watch, an additional world-time indication is portrayed by a wheel with 24 cities on display against black or white and further fitted with an inner 24-hour ring and an outer 24-hour ring. The additional world-time feature is dedicated to day-light saving or solar time. The cities in black are cities that do not incorporate daylight saving whilst cities displayed in white on the wheel are cities that do. The ingenuity behind the complication is sophisticated yet it serves a simple purpose.

The present example in blackened titanium is presented in excellent overall condition and is further part of a rare limited edition of 22 examples produced. The all black iteration of the Greubel Forsey GMT is a highly attractive example for collectors of complications and further charmed by the full set of accessories.
