Grand Seiko Just Embarrassed Rolex in 2025!?

Grand Seiko just dropped a bombshell in the world of horology with their all-new Spring Drive Caliber 9RB2—and it might just outshine Rolex’s brand-new Calibre 7135 in the Land-Dweller. In this video, I compare these two groundbreaking movements side by side. Grand Seiko's new "Ultra Fine Accuracy" boasts an insane ±20 seconds per YEAR, making it the most accurate mechanical movement powered by a mainspring ever. Meanwhile, Rolex's Land-Dweller comes with its own innovation—introducing the Dynapulse escapement and operating at 5 Hz, offering around ±2 seconds a day accuracy. But when you look beyond the specs… which brand really pushed the boundaries this year? Let’s break it all down—from history and design to innovation and, of course, accuracy. ⏱️ Is Grand Seiko finally winning the tech race? 👑 Or is Rolex’s legacy and new innovations still king? Drop your thoughts in the comments—I’d love to hear what side you’re on. #TeamRolex or #TeamGrandSeiko?
