Bamboo has come to the fore on the wave of green trends. It’s that wood that’s readily abundant, pretty to look at, and has many applications. And now we can add watchmaking to them: Reveal’s Bamboo watch uses the wood in the housing and band, creating a look that’s decidedly different while remaining classic and sharp. The grain’s natural beauty comes with the added benefit that it’s a very sustainable wood. On the flipside of this Eco coin, BP has partnered with a watchmaker recently to do a commemorative Gulf Spill watch made from tar balls and baby pelican feathers.
