The dial absorbs light through an array of tiny apertures on the front, suggesting the relationship between light and time.AQ6020-53X comes with a mother-of-pearl dial evoking the never-ending passage of time in the natural world. The contrast between the sophisticated mother-of-pearl pattern formed over many years and the second hand marking each precise second makes this watch uniquely striking. The presence of moments in the passage of eternal time - highlighted by ultra-precise accuracy of 1 second per year - is envisaged in the design.Both models feature the crystal motif for the case, crown and bracelet.
