The Enzo had no companion watch, but its successor, the Ferrari LaFerrari, does. Created by Hublot "entirely in parallel with the car" and "alongside the Ferrari teams," the MP-05 LaFerrari tribute watch is a similar test of how much gobsmacking gadgetry can be packed into a chassis. The manually-wound watch has 11 barrels set in a spine down the center that work together to provide a 50-day power reserve. So yes, it does need to be wound, but only once every seven weeks.
Watchmakers pursue partnerships with automakers and racing series like they're made of gold – which is, often enough, the case with the timepieces that ensue. Breitling has Bentley. Jaeger-LeCoultre has Aston Martin. TAG Heuer has McLaren. We'll let you draw your own conclusions about Porsche Design watches.
