Tiny solar sensors located on the watch dial capture light that is stored in an accumulator. The energy needed to run the quartz usually comes from a battery, but here the energy comes from natural or artificial light. This sustainable technology is enabling Tissot to create watches that run for several months without ever needing a recharge.
