The Sun & Moon watch collection features a movement that is based upon the position of the sun or the moon in the sky represented on the watch face. Within a month's cycle the Sun rises on the left of the dial and it slowly climbs in the sky until it reaches the crescent of mid month. Once past this point, the Sun then sets and disappears from view. Meanwhile, the Moon rises on the left. The raised numbers on the dial glow in the dark, enabling the wearer to read the time even in the dark. A genuine Italian leather croc-effect strap finishes this elegant timepiece. Quartz analogue multi-hand, day, date and moon phase Japanese movement, 5 ATM water resistant. One year guarantee.
