There’s no quiet way to introduce a watch like the Jacob & Co. God of Time, but beneath the dial design and precious metal, there’s a genuinely interesting mechanical idea at work. The headline claim is simple enough: this is the fastest tourbillon ever made, completing one full rotation every four seconds. That’s roughly 15 times faster than the classic one-minute tourbillon most collectors and enthusiasts grew up studying under a loupe. Rather than treating the tourbillon as a historical milestone, Jacob & Co. uses it here as a proving ground, asking what happens when you push one of watchmaking’s oldest complications well beyond its comfort zone.

Making that kind of speed possible required a movement built specifically for the challenge. The hand-wound Caliber JCAM60 centers itself on an ultra-light titanium tourbillon carriage that weighs just 0.27 grams, reducing inertia enough to survive rapid rotations. A constant force mechanism operating at one-sixth of a second helps control delivery, keeping the tourbillon spinning consistently across a 60-hour power reserve. Interestingly, the movement itself beats at a familiar 3 Hz, which makes the four-second tourbillon feel even more out of place, in a good way.

Visually, the God of Time ties into storytelling as much as mechanics. The dial features a handcrafted, three-dimensional rose gold sculpture of Chronos, the Greek god of time, positioned as if he were holding the high-speed tourbillon in place. Set against blue aventurine, the design resembles a miniature sculpture more than a traditional watch dial. The 44.5 mm rose gold case draws inspiration from Ionic Greek temple pillars, tying the mythological theme together. Limited to 60 pieces and priced at $360,000, the God of Time is a reminder that even the most established complications can still be rethought.
