2025 Grand Seiko Heritage "Katana" SBGA491G Spring Drive, Green Dial, Full Set
The Grand Seiko SBGA491G is a stunning U.S. Special Edition that embodies the artistry and precision for which Grand Seiko is renowned. Inspired by the traditional Japanese katana, its textured green dial reflects the appearance of shingane, the resilient inner core of a samurai sword, creating remarkable depth and changing character with every shift in light. Housed in Grand Seiko's iconic 44GS case, the SBGA491 offers an exceptional blend of Zaratsu-polished surfaces, razor-sharp case lines, and timeless elegance.
At the heart of the watch is Grand Seiko's legendary Spring Drive Caliber 9R65, combining the beauty of a mechanical movement with the unmatched precision of Spring Drive technology. Accurate to approximately ±1 second per day with a 72-hour power reserve, it delivers one of the smoothest sweeping seconds hands in all of watchmaking. Paired with a highly wearable 40mm stainless steel case and 100 meters of water resistance, the SBGA491 is equally suited for everyday wear or special occasions.
