Tokyo Lion Design

The greatest visual appeal is the bold case design inspired by the lion, Grand Seiko’s brand symbol. The case shape is based on the powerful claws of a lion, with a sculpted form that looks as if a solid block of metal has been carved away and shaped to grip the wrist.

Hairline Finishing

The hairline finishing emphasizes the expression of the metal and sharpens the impression of the lion-claw-inspired case. It gives the watch a powerful, sporty, and architectural presence.

Brilliant Hard Titanium

Brilliant Hard Titanium gives the watch both lightness and durability. It is harder than stainless steel, lighter like titanium, and has a bright white appearance. When polished by skilled craftsmen using Zaratsu polishing, it creates a refined yet strong finish.

Tentagraph Mechanical Chronograph

Tentagraph is Grand Seiko’s representative mechanical chronograph movement. Unlike Spring Drive models, this watch offers the mechanical feel and function of a traditional chronograph, with 30-minute and 12-hour counters for practical timing use.
