Background for the ZMX+01 watch was the world adventure performance theme. Inspired by the heights of the mountains and the endless landscapes of our world we created an extremely robust and high durability watch with interchangeable Top Rings including a dual time and oil floated compass bezel. The watch comes with a large dial opening to fit a matt, non reflective dial in to a high performance multi component case construction. The supplied interchangeable Top Rings are easy to exchange by turning them with one hand in the counter clockwise direction from the watch head.
