Spring Drive that is close to the urban active life. It is a model equipped with a third mechanism “Spring Drive” that enables high accuracy equivalent to that of quartz watches while using the mainspring used for mechanical watches as a power source. The second hand, which slides on the jet-black dial, makes the sweep hand movement created by the original mechanism look impressive. In the case design, the flat structure gives a strong impression, and the wide dial and slender bezel give a smart and sporty impression. The white Lumibright is laid out on the outside of the sharp index to improve visibility and complete a modern and active look.
