This design features a larger 41.4mm case size, a tapered bracelet, an aluminum bezel, and a tachymeter for enhanced practicality and visibility. The watch conveniently charges from both natural and electric light. This specific version showcases a stylish blue dial and bezel, with added splash for vibrancy.
