Greubel Forsey now offers its GMT Quadruple Tourbillon with a titanium case and adds eye-catching new blue hues to the dial of the highly complicated 46.5mm watch.
With its new case, the watch is one-third lighter than the original white gold model, which Greubel Forsey debuted in 2019. To complement that lightness, the watchmaker attaches a new rubber strap, which quite effectively enhances the modern profile of the watch, adding a touch of sportiness. (An alligator strap is also available.)
As noted, the new dial treatment maintains that message, with an electric-blue-hued hour ring and power reserve indicator. Previously all black, the circular-grained hour ring retains its polished bevels, echoing the mainplate, which Greubel Forsey has made more contemporary with its own gray frosted and spotted finishing. The plate boasts a full complement of polished bevels and countersinks.
Greubel Forsey has also re-faced one of the watch’s many technical highlights: its titanium GMT globe. This miniature planet Earth, which Greubel Forsey debuted in 2011, now displays the continents amid newly bright blue seas, a livelier depiction than the globe rotating within the white gold GMT Quadruple Tourbillon two years ago. The new ocean color nicely matches the new blue finish of the power reserve, hour circle and strap.
Many displays
These cosmetic changes haven’t altered the globe’s dramatic time display. The Earth is surrounded by a fixed 24 hours ring around the Equator. This ring displays local time for all the longitudes and takes into account the day/night with an indicator. A peek through the side of the case, through a sapphire window adjacent to the globe, reveals a clear view of the Equator and the southern hemisphere.
Beyond the new livery, the latest Greubel Forsey GMT Quadruple Tourbillon remains a feast for the eyes. The multi-level, three-dimensional dial offers the main hours and minutes subdial at the highest point (between 1 o’clock and 2 o’clock), with the coaxial small seconds and second time zone at 4 o’clock forming the second highest point.
You may recall that each Double Tourbillon 30° features a first cage rotating in one minute and angled at 30°, fitted inside a second upright cage that rotates once in four minutes. Greubel Forsey explains that the combination of the inner cage inclination and the different rotational speeds of the two cages cancel any timing variations. A spherical differential transmits the average timing rate of all four of the tourbillon cages, improving their chronometric performance.
The back of the watch also delivers both awe and information. Universal time can be spied, with a fixed 24-hour scale showing day and night zones and a disk with abbreviations of twenty-four cities. The same disk also distinguishes between the time zones that utilize Daylight Saving Time and those that don’t.
Greubel Forsey plans to make eleven examples of this new titanium-cased GMT Quadruple Tourbillon, each priced at 760,000 Swiss francs. The watch will be made, eventually, as an edition of sixty-six examples.
