Welcome to our TIME Collection. Our Classic Series is tried and true - sleek metal styles, fashionable sport experience, silicone and even slim leather applications. Historically, fashion has always met function in the form of a watch, and we are proud to expand upon functionality by providing the ability to engrave directly upon the caseback. All Doc Tock watches boast a hypo-allergenic caseback and buckle, and the caseback itself is always engravable. All Doc Tock watches come with a 1-year warranty, a medical alert wallet card and our signature, reusable metal box.
