Grand Seiko has unveiled two remarkable timepieces at its latest showcase. Leading the charge is the Tentagraph — the brand’s first mechanical chronograph — housed in the muscular Tokyo Lion case. Alongside it stood the Spring Drive U.F.A., a technical marvel featuring an industry-leading ±20 seconds per year accuracy from a purely mainspring-driven movement.
The new Tentagraph and Spring Drive U.F.A. from Grand Seiko make a compelling case for your next watch splurge

The Tokyo Lion series, inspired by the power and poise of its namesake, stands for strength and precision — values that the Tentagraph pushes even further. At its heart ticks the Caliber 9SC5, a high-frequency movement beating at 10 times per second, delivering a robust three-day power reserve even with the chronograph engaged.
Crafted from Brilliant Hard Titanium — a material twice as hard as steel yet remarkably light — the Tentagraph debuts this alloy in Grand Seiko’s Sport Collection. Refined pushers, razor-sharp diamond-cut indexes for enhanced legibility, and a mane-textured dial nodding to the lion’s legacy complete this confident evolution in form and function.
Complementing the bold case is a newly developed rubber strap, finished with a discreet lion paw motif on its underside. From the claw-like contours of the case to the vertically aligned sub-dials, every element of the Tentagraph embodies Grand Seiko’s elegance.
The watch starts at ₹16,00,000.

Grand Seiko also introduced the Spring Drive Caliber 9RB2. Now carrying the U.F.A. (Ultra Fine Accuracy) hallmark, this movement achieves an extraordinary ±20 seconds per year accuracy—setting a new benchmark for mainspring-powered precision.
The Caliber 9RB2 debuts in two Evolution 9 Collection references – one in Platinum 950 with a crocodile leather strap, the other in lightweight High-Intensity Titanium. Both feature dials inspired by the frosted landscapes of the Kirigamine Highlands, capturing the ethereal textures of Shinshu’s ice-covered forests. The rotor is engraved with ‘SPRING DRIVE ULTRA FINE ACCURACY,’ marking this debut.
The watch starts at ₹10,00,000.
