Greubel Forsey GMT Black

The Greubel Forsey GMT Black was introduced at SIHH 2015, representing the pinnacle of world time complications combined with a tourbillon. This latest edition features a lightweight titanium case coated with ADLC (Amorphous Diamond-Like Carbon), giving the watch a striking deep black finish while offering superior scratch resistance and elasticity.

Design & Case Architecture of Greubel Forsey GMT Black

The 43.5 mm Greubel Forsey GMT Black retains the iconic GMT layout. Its standout feature is the three-dimensional rotating globe at 7 o’clock, which revolves in real time, indicating world time and day/night cycles intuitively. The tourbillon cage at 5 o’clock is tilted at 25 degrees and completes a rotation every 24 seconds, showcasing both mechanical ingenuity and aesthetic craftsmanship. Despite the complex construction, the watch wears comfortably due to titanium’s lightweight properties.

Dial & Complications

In addition to the main time dial, the Greubel Forsey GMT Black features small seconds, a power-reserve indicator, and a second time-zone subdial. The sapphire caseback reveals a 24-time zone disc with major cities and an inner 24-hour ring with daylight saving time (DST) indications. This watch exemplifies Greubel Forsey’s philosophy of integrating functionality, legibility, and mechanical artistry in one instrument.

Movement – In-House Caliber GF05

The watch is powered by Greubel Forsey’s in-house Caliber GF05, operating at 21,600 vibrations per hour with a 72-hour power reserve. The movement consists of 40 jewels and is meticulously finished, highlighting the brand’s dedication to high-end horology. Every component, from the rotating globe to the tourbillon, is crafted to deliver precise timekeeping combined with visual sophistication.

The Greubel Forsey GMT Black is limited to only 22 pieces worldwide, with a retail price of approximately 480,250 EUR.
