Power reserve: 72 h, 21600 variations / hours
"Since its introduction in 2015, the Jacob & Co. Billionaire has reached fame as the watch coveted by all with a price tag surpassing $18 million. With only one in existence worldwide, the Billionaire is a unique piece adorned with Emerald-Cut Diamonds with an approximate carat weight of 260 carats.
Now, Jacob & Co. is using the ASHOKA® diamond for the very first time in a diamond-encrusted tourbillon timepiece.
The one-minute tourbillon of the Billionaire Ashoka is haute horlogerie's response to the high jewelry tour de force that surrounds it. With its black mirror polished upper cage - a finishing technique that requires immense patience and dexterity - hand-beveled and hand-polished edges and calculated operation, the tourbillon is the only complication to live up to the breathtaking visual experience of the diamond-set exterior.
The tourbillon encapsulates the balance wheel, hairspring, escape wheel and a number of other crucially important, superbly finished components. Its most careful assembly is followed by a painstaking fine-tuning process, allowing the Billionaire to keep accurate time throughout its extended, 72-hour power reserve."
