Ticking inside this iteration of our iconic 1960s marlin is a tried and true 21 jewel japanese automatic movement, creating a contemporary timepiece that honors our watchmaking history. Powered by your motion as you wear the watch, the movement can store a maximum 40 hours of energy. If motionless for 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 our original marlin design, this watch features the iconic domed acrylic crystal and retro style applied indices, complemented by a sturdy 40mm recycled stainless steel case with exhibition caseback and black dial. Paired with an eco friendly natural leather strap sourced from the leather working group lwg.
