A spring drive model that brings together unique and shining parts into a permanent beauty. The third mechanism, “Spring Drive,” which uses the mainspring used in mechanical watches as a power source and enables high precision equivalent to that of quartz watches, is housed in a case that stands out from other Grand Seiko watches. I did. The case design, which shines in the light, has a mirror finish on multiple sides, and the black dial, which has been super-three-dimensionally stamped, is both easy to see and has a high quality feel. Bold crown guards and legs have a unique presence that has never been seen before at Grand Seiko. The movement of the second hand, which is different from the mechanical and quartz movements created by the original mechanism, is a sweeping hand movement that flows smoothly over the dial. The maximum winding duration is about 72 hours (about 3 days), and you can check the remaining operating amount on the power reserve display at the bottom left.
