Happy birthday to Jacob & Co. which is 30 years young. To celebrate these three decades in exceptional style, the brand presents the Twin Turbo, a world-first Grand Complication sports model combining two triple-axis tourbillons with a minute repeater. Sounding on a pleasingly low-pitched tone, the minute repeater with cathedral-type gong strikes the hours, the decimal (10 minutes instead of the traditional 15) as well as the minutes.

A special poising system ensures that the twin tourbillons rotate in sync around their three axes – 40 seconds around the first, eight minutes around the second, and three minutes around the third – thereby creating a pleasingly similar, symmetrical visual effect. This timepiece features a sleek, sporty look and its titanium and carbon composition make it extremely light on the wrist. The two tourbillons, together with the minute repeater, are fitted within a 63-part case featuring an automobile-inspired design. It took Jacob & Co. two years of R&D – corresponding to around 3,300 hours of work – to develop the Twin Turbo Triple-Axis Double Tourbillon Minute Repeater.
