The growth and consequent patterns of tree rings is a common method used in tracking time and dating. Though this practice operates on the scale of years, Moscow-based Studio Lebedev has transposed this idea to a more user-friendly scale of minutes and hours. Stubus Watch is a lightweight, waterproof time keeper that boasts a decorative face of two discs representing a tree’s cross section. In each is a small notch that serves as the second and hour hand, a clever but subtle way to merge function and fashion. Equipped with a leather wristband, Stubus is a stylish choice inspired by science.
