ZEN’s design inspiration comes from the sun which is applied by the human beings for the initial pursuit of time, work with sunrise and rest with sunset. Design features: 1. In the dial, the sun rotates for one circle on the mountain peak to show the 24 hours a day through sunrise and sunset. 2.Unlike the time adjustment of ordinary watches, ZEN adopts back adjustment. Press the button of 8 word bits by the thumb of left hand and rotate at the bottom by the index finger of right hand to adjust the time. The process for the rotation of the sun can be felt intuitively which is full of fun.
