Turbo-Charged

To mark the 30th anniversary of its founding in 1986, Jacob & Co has launched a sports Grande Complication model in keeping with its youthful vigour.

The new model, the Twin Turbo, combines two tripleaxis tourbillons and a minute repeater.

Through a poising system, these tourbillions maintain a consistent rate set at 40 seconds, three minutes and four minutes per cycle so as to turn symmetrically and at the same pace.

With a deep-sounding chime, the minute repeater with a cathedral gong offers a modern approach to striking the hour, the 10 minutes instead of the traditional 15 minutes, and the minutes. A safety system prevents its striking during time setting.

Rarely for a grand complication, the two tourbillons and minute repeater are housed in a shaped watchcase equipped with 63 components.

Its sporty look combines titanium and carbon that provide ultra lightness. Inspired by automotive design, its flange is trimmed in red neoralithe and the smoked sapphire crystal opens on to its motor featuring two triple-axis tourbillons.

The transparent case back reveals an architecture of triangles in openwork metal.

According to Jacob & Co, the Twin Turbo required two years of research and development, and 3,300 hours of work to be completed.
