The center of the dial is mother-of-pearl in Grand Seiko’s signature blue.

The powerful profile of the lion has been an enduring symbol of Grand Seiko ever since the first Grand Seiko introduced in 1960, when a gold medallion depicting a lion graced the case back.

At Watches and Wonders Geneva 2022, Grand Seiko introduced a Spring Drive jewelry watch inspired by the white lion. Today sees the introduction of another Spring Drive masterpiece in which the strength and power of this majestic creature are brought to life through the jeweler’s art, only now it is graced by blue sapphires in honor of Grand Seiko’s signature color.

Combining the precision of Spring Drive, high legibility through carefully placed gems, and exquisite artistry and craftsmanship, this remarkable creation is in every way a showcase of the ideals of Grand Seiko.

The case and dial have 5.62 carats of diamonds and 1.25 carats of blue sapphires, all set by hand.

The strong and angular lugs speak to the power of the lion. No fewer than 112 diamonds are embedded in the upper surfaces of the case and a further 60 baguette-cut diamonds adorn the bezel. All of the diamonds are set so precisely that they seem to create a single, flat surface. The seconds hand is tempered to a perfect grey color to match the overall tone, and a single brilliant-cut blue sapphire is set into the crown.

Hand craftsmanship of the highest order

On the dial, the blue sapphires and baguette diamonds are tapered and serve as hour and minute markers that surround the mother-of-pearl whose depth and texture create a tranquil space at the center. All these gems are set by hand between pairs of very thin 18k white gold rails by the most skilled of the jewelry craftsmen and women of the Shinshu Watch Studio, located in the Shiojiri facility in Nagano prefecture, where Grand Seiko Spring Drive watches are made. Forty-eight additional diamonds and 12 blue sapphires are individually set around the markers to further enhance the piercing depth and beauty of the dial.

The case is treated with a form of Zaratsu polishing specially developed for Platinum 950
to achieve a distortion-free mirror finish.
