The twin tourbillons power most of the watch, including the main time display and the monograph pusher. Each of the tourbillons are composed of 104 components and weight just 1.15 grams. It’s amazing what they can do.
Minute repeaters are the hardest complication for a watch company to make but, by God, Jacob & Co. wanted to see how far they could go. Most minute repeaters conform to the hours, quarter hours, and minutes standard, but the Twin Turbo doesn’t do that. Instead, it chimes on demand ten-minute intervals after the hours and before the minutes. This kind of decimal repeater, according to Jacob & Co., is very rare in high watchmaking.
