In what we can only describe as the pinnacle of independent watchmaking, Greubel Forsey once again takes the center stage at Baselworld 2018. Highlighting their expertise in 'black polishing', the brand released four new watches that capitalize on the art of 'black polishing'. One of these four watches is the new Greubel Forsey Double Tourbillon Technique Blue. A few weeks ago we featured the Greubel Forsey Quadruple Tourbillon Blue here.

This timepiece measuring 47.50 mm in diameter full of intricate details and a perfect example of ultra 'haute horlogerie' is not only worthy of a detailed review, but also worthy of admiration. Integrated into the complex three-dimensional movement architecture, the sapphire crystal chapter ring is transformed into a window through which to observe a miniature world where the eye is drawn from one gear to the next, enabling careful observation of each separate element.

Things to Know About the Watch

The multi-layer complex dial features a sapphire crystal disc around the perimeter of the case with applied markers and a 12 o'clock numeral marker. The tridimensional depth of the mechanism and the dial are a real treat for the eyes.

The dial also features a Double Tourbillon 30° mechanism with sapphire crystal 4-minute engraved indicator for the outer tourbillon at 6, a 120-hour power reserve indicator at 3, a small seconds register at 9 o'clock and a black finished 22K gold cover for the four coaxial barrels that is engraved with "Greubel Forsey Four Coaxial Barrels" in bas relief text.

Just as if the dial and the movement weren't enough treat for the eyes, Greubel Forsey decided to go the extra mile and included two intricately hand engraved plates screwed to the case band on both sides bearing the now usual text in French that describes the values and attributes of this horological masterpiece: 'Savoir-Faire', 'Inventeurs Horlogers', 'Créativité', 'Technicité', 'Univers Original', 'Bienfacture d'Exception', 'Oeuvre Unique', 'Noblesse Esthétique', 'Inventeurs Horlogers', 'Créativité' and 'Technicité'.

The Movement

The fascinating movement inside this watch is the manual-wound calibre Greubel Forsey GF02s with with patented tourbillon. The movement on the back is as fascinating as on the front. The movement is composed of 385 parts, two tourbillon cages with 132 parts, four coaxial series fast rotating barrels, 43 olived-domed jewels in gold chatons, nickel silver main plates and bridges frosted with polished beveling and nickel-palladium treatment, an inner tourbillon positioned at an angle of 30° that rotates once every minute and an outer tourbillon that rotates once every four minutes.
