Ticking inside this iteration of their iconic 1960s Marlin® is a tried-and-true 21-jewel automatic movement, creating a contemporary timepiece that honors Timex's watchmaking history. Powered by your motion as you wear the watch, the movement can store a maximum 40 hours of energy. If motionless longer than 40 hours, wind the watch using the crown until you feel resistance, set the time, and place it back on your wrist where every motion will supply the energy. True to the original Marlin design, this watch features the iconic domed acrylic crystal, complemented by a stainless-steel case, navy dial, and classic brown leather strap sourced from the S.B. Foot Tanning Company.
