Watch brand Swatch has just released a new line for Spring/Summer 2014. “SISTEM51″ features four different colorways of the same unique style. Entirely Swiss-made, the watch features a 90-hour power reserve, and its distinguishing feature is a semitransparent back which reveals the mechanics at work inside the watch. And that includes just 51 parts in five modules which still manage to provide a self-winding mechanical movement. The design includes a silicone watch strap and a lightweight, water-resistant plastic case. It comes in four different bold colorways, including blue, red, white and black. The “SISTEM51″ styles are available from Swatch boutiques worldwide and selected retailers.
