Grand Seiko Tentagraph
Grand Seiko Tentagraph in the Tokyo Lion design
A new milestone: the series brings a distinctive edge to Grand Seiko sports watches with sharp angularity and bold case design.
A Powerful Symbol
The lion symbol reflected the aim of the original Grand Seiko team to create the very best timepiece they could in terms of accuracy, durability, and beauty. Inheriting the lion symbol, this watch was developed in the relentless pursuit to advance the essence of the Grand Seiko sports watch. From its case design rich with symbolism to its refined rubber strap and textured dial, numerous aspects have evolved from previous lion-themed timepieces in pursuit of key sports watch values such as legibility, durability, comfort, and beauty.
"A design that pursues the essence of a sports watch"
This watch marks the first time that Grand Seiko’s Brilliant Hard Titanium has been adopted in the Sport Collection. The alloy is brighter than traditional titanium, causing the case’s hairline-finished and Zaratsu-polished surfaces to appear even more radiant, enhancing the strong design.
Designed for wearing comfort
The newly developed rubber strap has a tensile strength of nearly 2.7 times the typical silicone strap used for Grand Seiko. It was created for this watch, and its brown color pairs perfectly with the patterned dial. Not only does the strap have an excellent texture, but the motif on the back was inspired by the lion’s paw, providing a playful design detail even if it is only visible to the wearer. Combined with the slightly curved case back, the new strap ensures comfort and stability on the wrist befitting a Grand Seiko sports watch..
