The AM08 watch utilizes a special Solar Power Movement in combination with 
- the solar powered Seiko.
 
This uses all sorts of light to charge its state-of-the-art titanium lithium ion battery.  
So, it can be charged indoors or out and does not need to be plugged in. 

However, it loves sunlight as that will charge it the quickest. -Ready power for 
a day in 1 minute: Just one minute of sunlight delivers one hour of charge 
and the watch is fully charged after just 5 hours.
(5 hours in direct sunlight or 45 hours in the office)
 
And if your AM08 becomes low on power, 
the seconds hand will tick every 2 seconds to let you know it needs light.

At the heart of AM09 watches is a high-precision, Japan made automatic 
movement . It making for a smooth sweeping second hand across the dial.
