We applied a new movement to an old favorite. Ticking inside is a tried-and-true 21 jewel automatic movement for a more accurate, longer lasting timepiece. 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 it and place the watch back on your wrist where every motion will provide energy for the movement. The stainless steel case is complemented by its black dial and black croco-pattern natural leather strap. Like our craftsmanship and commitment to our heritage, some things are just automatic.
