Making its debut at the SIHH, the co-founder of Greubel Forsey discussed the company's goals and presented its three major inventions before introducing this year's novelties. 'Watchmaking is the only profession I know of that combines science, mechanics and art,' said Stephen Forsey at the fair in January. 'Our aim is to perfect each of these aspects in every single watch.' Robert Greubel and Stephen Forsey have often said over their 20-year partnership that they are 'first and foremost inventors'. Their creation of the Experimental Watch Technology (EWT) platform is testament to their thirst for improvement and innovation. 'The human being is a naturally curious spirit,' Forsey said. 'And watchmakers are particularly so.' He described the EWT as a platform for them to invent, experiment, develop, test and manufacture new concepts. Their research is primarily targeted at improving timekeeping precision, and the brand's three finished inventions all achieve that purpose. The first invention, the Double Tourbillon 30?, features one tourbillon rotating inside the other, while the Quadruple Tourbillon movement contains four asynchronous tourbillons for increased accuracy. The third invention, the Tourbillon 24 Secondes Incline, has an inclined tourbillon cage to minimise gravitational influence. This year's novelties expand upon the collections created with these inventions, with the launch of the Double Tourbillon Technique, in red gold, and the platinum editions of the Tourbillon 24 Secondes and the Invention Piece 3. The Double Tourbillon Technique makes use of the Double Tourbillon 30o mechanism, with four fast-rotating co-axial barrels added for a 120-hour power reserve. Forsey said that many of the watch collectors who had visited the booth had expressed interest in the Double Tourbillon Technique in particular. The new edition comes in a red-gold case, with the power reserve indicator visible at three o'clock and a sub-seconds dial at nine o'clock. Both the Tourbillon 24 Secondes and Invention Piece 3 use the Tourbillon 24 Secondes Incline mechanism in which the tourbillon cage performs a complete rotation in 24 seconds while positioned at a 25-degree angle. The high speed and incline correct a flaw in the equilibrium of a tourbillon by placing the balance and spring parallel to the earth's surface, thereby improving accuracy. The Tourbillon 24 Secondes model has a power reserve of 72 hours, with the indicator positioned at two o'clock. The small seconds sector is located at six o'clock, while the tourbillon cage and 24-second tourbillon rotation indicator are displayed at eight o'clock. The new edition features a platinum case with a black-gold dial, with a lateral window showcasing the tourbillon cage. While the Tourbillon 24 Secondes features a classic time indication with hour and minute hands, the Invention Piece 3 makes use of two concentric discs for a different look. The outer disc shows a 24-hour display with the present hour indicated by a large red arrow, while the inner disc shows the minutes indicated by a small blue arrow. The 72-hour power reserve indicator is located at two o'clock, the sub-seconds dial at five o'clock and the tourbillon cage is displayed with a lateral window at eight o'clock. The new edition is cased in platinum paired with a hand-sewn alligator leather strap.
