Located in Iwaizumi in eastern Iwate Prefecture, Ryūsendō Cave is known for its extensive subterranean galleries arching over deep sunless lakes of clear blue water. This effect is captured by the dial’s vibrant dial color and dazzling pattern.
The stainless steel case of SBGK015 is polished by a special Zaratsu method developed to accentuate the beauty of the case's curved surfaces. The dial and sapphire crystal are also curved to give the watch a classic look. Additionally, the dial features hand-bent minute and power reserve hands, a nod to classic watch design.
Caliber 9S63 is a slimmer mechanical package, and it offers a small seconds register at the nine o’clock position and a power reserve indicator at three. The thinness of the movement allows for a slimmer, dressier design overall, allowing SBGK015 to slide comfortably under a shirt cuff.
SBGK015 is a U.S. Limited Edition of 300 watches.
