A Spring Drive Chronograph that reveals the strength of the lion.The imposing case design, which conveys the power of the lion, fits firmly in place on the wrist. Grand Seiko’s unique High-intensity titanium is used in the case and bracelet, making for a lightweight wearing experience and pure joy to wear. The motif of the lion’s mane comes to life on the bright white dial and combines with the wide indexes and hour hand to grant the watch a remarkably striking design. It communicates the power and courage of the lion and reminds us of our inner strength. The SBGC253 Spring Drive Chronograph boasts features appropriate to a sports model, such as the Lumibrite coating on the indexes and hands, which aids nighttime legibility, and 20 bar of water resistance. Add to that the chronograph and GMT functions, which make this model such an incredibly useful sport watch and one to be reached for often. It’s also highly accurate, powered by the precise Caliber 9R86 Spring Drive movement, delivering an average precision of ±15 seconds per month (±1 second per day).
