Use nature to power your timepiece with the Meridiem Free Energy AM Watch Collection. This series features two beautiful styles: the AM08 – Solar and the AM09 – Auto. The former gathers energy from environmental lights while the latter uses the movement from your arm to gain power. With this nature-based technology, the Meridiem AM Watches require no batteries and can be used for years to come. The AM08 – Solar works with a Seiko movement and a titanium lithium ion battery. Sunlight charges it the fastest requiring only one minute of exposure for an hour of power. On the other hand, the AM09 – Auto has a Japanese movement with a whopping 21 jewels. Reducing friction and ensuring accuracy, this style holds 40 hours of power reserve. Accompanying both of the Meridiem AM Watches is a combination of stainless steel, sapphire crystal, and luxurious leather.
