Features

The vibrant energy and natural beauty of white birch forests expressed in a Hi-Beat 36000.

Inspired by the lush white birch forests surrounding the Grand Seiko Studio Shizukuishi, this Grand Seiko luxury watch features a richly textured dial in a vibrant, life-imbued green tone. The design captures the dynamic vitality of the forest landscape near Grand Seiko’s renowned mechanical watchmaking studio, expressing nature’s energy through refined Japanese craftsmanship. 

At its core is the Grand Seiko-exclusive Hi-Beat Caliber 9SA5, an advanced automatic mechanical movement engineered for exceptional precision and performance. Equipped with the innovative Dual Impulse Escapement and twin-barrel architecture, it operates at a high frequency of 36,000 vibrations per hour while delivering an impressive power reserve of approximately 80 hours when fully wound.

The case and bracelet are crafted from Ever-Brilliant Steel, a "super" stainless-steel alloy known for its brilliant white sheen and outstanding corrosion resistance. Combining cutting-edge mechanical engineering, nature-inspired design, and superior materials, this Grand Seiko Hi-Beat luxury timepiece embodies the harmony of innovation, durability, and elegance sought by discerning watch collectors.
