Unveiled at the 24th edition of the World Presentation of Haute Horlogerie (WPHH) in January 2014, Frank Muller’s in house poetic complication – the Giga Gong Tourbillon features a rhythmic chime that strikes every hour is giving a new dimension to the renowned Giga Tourbillon.
Created in 2011, the Giga Tourbillon bears the world’s largest tourbillon. A sheer technical marvel powered with four barrels, it embraces a 20 mm diameter tourbillon on the dial that occupies almost half of the watch. Branching from this Giga tourbillon, the new Giga Gong Tourbillon takes it a step further.
The new in-house designed and manufactured manual watch is enhanced with an exciting Striking Hour complication that strikes at every hour. The four barrels are paired in series to provide a power reserve of 6 days. An ON-and-OFF push-button at 4 o’clock can set and de-activate the chime with an indicator of this function at 3 o’clock on the dial.
The entire mechanism is flawlessly decorated with circular graining, rhodium plating and hand chamfering. Seen in an 18-carat gold casing, this collection is available in two versions – the classic Cintrée Curvex and Round.
