WeWOOD

The WeWOOD timepieces are not made with artificial or toxic materials

The philosophy of the brand is that "One timepiece plants one tree, and together we help to ensure the health and survival of the natural world"

One Watch  – One Tree – One Planet

Great idea, isn't it?

These are some of my favorite models but there are much more on their site

And also you can save some money if you buy them through this coupon site: http://www.therawfeed.com/stores/we-wood-us
