Bugatti’s newest engine is a tourbillon. The motor-driven marvel can’t be taken out on the road, but it is crowned by a W16, and it will keep very good time.

The watch is the work of Swiss firm Jacob & Co. The timepiece’s W16 is hand cut from sapphire crystal, and boasts moving parts: crystal pistons and a crankshaft, with a pair of turbos to back them up and four blue springs to suspend the movement. The astonishing mechanical flourishes say much about the influence of nouveau Bugatti and the craftsmanship of the watchmaker.

The watch may be perceived as a de rigueur accessory for a Bugatti owner, or at the least a remarkable and comment-worthy addition to a serious watch collectors lineup. Only 250 examples will roll out of Jacob & Co., each priced at $280K.
