In every Heritor, there ticks a precision-crafted jeweled automatic movement. An automatic movement uses the energy in a spiral spring – called a mainspring. This mainspring is self-wound by the natural movement of the wrist, leading to a fully functional timepiece. More than function, the Heritor Hurst features a beautiful 316L surgical-quality stainless steel case and bracelet. It has a uni-directional bezel and a screw-down crown. Aside from its luminous hands and 12 hour markers, it also has a date display. It's water-resistant for up to 200 meters (660 feet), perfect for any water sports activities, such as scuba or skin diving.
