Grand Seiko Unveils “Sunrise Tentagraph” and “Moonlit Birch” in Evolution 9 Collection

 

Grand Seiko has introduced two new Evolution 9 watches that beautifully capture Japan’s natural landscapes: the SLGW006 “Sunrise Tentagraph” chronograph and the SLGW007 “Moonlit Birch” manual-winding Hi-Beat. Both pieces highlight the brand’s artistry in combining traditional inspiration with advanced watchmaking.

The “Sunrise Tentagraph” is a limited edition of only 300 watches. Its copper-pink dial, inspired by the morning glow on Mount Iwate, is housed in a 43.2mm case made from polished Grade 5 titanium, 18k rose gold, and ceramic. The custom fluted bezel doubles as a minute track, while inside, the Caliber 9SC5 movement delivers 72 hours of power reserve.

On the other hand, the “Moonlit Birch” is a dress watch designed with quiet elegance. Its navy-textured dial reflects the look of birch tree bark under moonlight, inspired by the forests of Hiraniwa Plateau. Set in a slim 38.6mm stainless steel case, it runs on the Caliber 9SA4 manual-winding movement, beating at 36,000 vibrations per hour. This high-beat mechanism ensures accuracy and offers an impressive 80-hour power reserve. A navy calf-leather strap completes the refined look.

Both watches will be available in October 2025, with the “Sunrise Tentagraph” priced at $22,600 USD/£19,650 GBP and the “Moonlit Birch” at $10,000 USD/£8,600 GBP, available through Grand Seiko Salons.
