Watches And Wonders 2025: Grand Seiko Unleashes The Tokyo Lion Tentagraph SLGC009 Mechanical Chronograph

When Grand Seiko first introduced the Tokyo Lion’s brutalist aesthetic in 2019, it wasn’t just another watch - it was a statement. Bold, angular and unapologetically striking, the design was powerful and precise. Now, Grand Seiko has taken that legacy and elevated it to new heights with the Tokyo Lion Tentagraph SLGC009, the brand’s first-ever mechanical chronograph movement, housed in an evolved Tokyo Lion case.

Debuted by Grand Seiko at Watches and Wonders 2025, this isn’t just an update - it’s a revolution. The Tentagraph isn’t merely a chronograph, it’s a testament to Grand Seiko’s relentless pursuit of perfection in accuracy, durability and sheer visual magnetism.

A Dial That Roars To Life

The moment you lay eyes on the Tentagraph’s dial, you’ll understand why this watch is special. The textured pattern mimics the flowing mane of a lion caught mid-stride, dynamic and full of movement. At 3, 6 and 9 o’clock, three-dimensional sub-dials are seamlessly inlaid, reducing the gap between markers and hands for crisp, instant legibility.

Then there are the diamond-cut indexes - sharp as a lion’s claws and standing taller and bolder than ever. Each one is packed with Lumibrite, ensuring legibility all day long.

Brilliant Hard Titanium: A First For Grand Seiko Sport

For the first time in the Sport Collection, Grand Seiko has employed Brilliant Hard Titanium, an alloy that outshines traditional titanium with a brighter, more radiant finish. The 43mm case is a masterclass in contrast - Zaratsu polishing creates mirror-like surfaces, while hairline brushing adds a rugged, sporty edge. It’s a watch that gleams with sophistication but wears like a true tool watch. It offers 200 meters of water resistance.

The new brown rubber strap isn’t just an afterthought as it’s a 2.7x stronger option compared to standard silicone, built specifically for this model. The textured surface feels premium, but the real surprise? Flip it over, and you’ll find a subtle lion’s paw motif - a playful secret just for the wearer. Paired with a contoured case back, it ensures a snug, comfortable fit.

Pushers With Purpose

Every detail on the Tokyo Lion Tentagraph SLGC009 introduced at Watches and Wonders 2025 has been rethought for performance and tactile satisfaction. The redesigned chronograph pushers deliver a satisfying click, engineered for precision engagement. Meanwhile, the claw-inspired lugs and bezel are more pronounced than ever, reinforcing the watch’s bold, aggressive stance.

The Heart Of The Beast: Caliber 9SC5 Tentagraph

The name “Tentagraph” isn’t just cool - it’s a breakdown of what makes this movement extraordinary:

• Ten beats per second (36,000 vph) for ultra-smooth chronograph operation.
• Three days of power reserve, even with the chronograph running.
• Automatic winding for effortless wearability.
• Chronograph functionality that’s as precise as it is satisfying to use.

This is Grand Seiko’s first in-house mechanical chronograph, and it doesn’t just meet expectations - it delivers even beyond them.

Final Thoughts: A Watch That Demands Attention

The Grand Seiko Tentagraph isn’t just another luxury chronograph but rather a symbol of evolution. From its daring design to its cutting-edge movement, every element has been refined in the spirit of the lion: fearless, precise and utterly captivating.

For those who demand performance without compromise and style without apology, the Grand Seiko Tokyo Lion Tentagraph SLGC009 isn’t just a watch - it’s a statement. And it’s ready to pounce onto your wrist.
