About this watch

The Grand Seiko SBGJ021 Automatic Hi Beat 36000 GMT, also affectionately known as the Dawn of Mt. Iwate, is a stunning watch that combines aesthetics with functionality. Manufactured in 2016, this limited edition piece is restricted to just 500 units, making it a collector's dream. The watch showcases a vibrant red dial that’s more than just a color; it’s a celebration of the breathtaking dawn over Mt. Iwate, which is a significant part of Japan's natural beauty and culture. With its striking design, high-performance movement, and practical features, it appeals to both collectors and casual wearers alike. The watch has a round shape with a diameter of 40.00 mm and a height of 14.30 mm. Crafted from stainless steel, the SBGJ021 not only looks good but is also built to last. The use of sapphire glass on the top adds a layer of protection, ensuring that scratches and scuffs are kept at bay. Plus, with a water resistance of 100 meters, you can wear it with confidence whether you’re at the beach or caught in a drizzle. What truly sets the SBGJ021 apart is its movement. It houses the Grand Seiko caliber 9S86, a self-winding 'high-beat' movement that operates at a staggering frequency of 36,000 oscillations per hour. This means that the watch delivers remarkable accuracy, with a deviation of just -5 to +3 seconds per day.
