First launched in 2019 (you can read about it here), the exceptional GMT Quadruple Tourbillon designed by Robert Greubel and Stephen Forsey is now available in a brand new limited edition titanium with new colours and finishes.

In this watch, the quadruple tourbillon is combined with a jaw-dropping interpretation of the GMT function from the iconic rotating globe.

The four tourbillons are constructed in pairs in a unique compact cage system. Each of these two systems is modeled on a 30° double tourbillon, with the first cage rotating at 30° in one minute, mounted in the second upright cage, and completing a full in four minutes rotate.

A spherical differential is used to average the timing of the two autonomous oscillators to improve timing performance, and the system is protected by two patents.

In this new edition, the GMT Quadruple Tourbillon’s 46.5mm x 17.45mm case is made of titanium, a material that is strong, corrosion-resistant and lightweight, reducing its weight by more than a third compared to a white gold case.

All of this is built on different levels, culminating in the main hours/minutes dial located between 1 and 2 o’clock, the dial presents several new decorative details such as the circular grained hour ring with polished bevels And the 72-hour chronograph power-reserve indicator that appears for the first time comes in bright blue or on the main plate, now brushed with polished bevels, countersunk holes and ruled sides in a grey finish. http://www.chronowrist.ru

The globe at 8 o’clock, used to simultaneously display several different time zones, is highlighted in blue. A sapphire crystal window around the equator completes the watch, offering a complete view of the Earth in motion.

The 3 Hz (21,600 vph) hand-wound movement consists of 805 parts, including three rapidly rotating barrels.

The Greubel & Forsey GMT Quadruple Tourbillon titanium strap is perfectly matched with the blue rubber strap.
