Today ends, successfully, the Kickstarter run of the Plug & Feather watches we wrote about earlier, which have unique stone faces. Now another watch made from an elemental material--wood--is also nearing the end of its crowdfunding run. And interestingly enough, these latter watches were designed by two teenage brothers.

Reed and Riley Stephens are 18 and 16 years old, respectively, and come from a line of woodworkers, following in the footsteps of their father and grandfather. Their Ambici watches come in ebony, koa, maple and sandalwood, and were carefully designed to avoid a potential materials conflict: Wood movement.

[With other wooden watches] the shrinking of the wood over time...often leads to a cracked crystal that is challenging to replace simply because the opening of the watch is now smaller. So essentially, there's an expiration date on the watch because of its wooden case....

Ambici watches [feature an] internal metal casing [that] prevents the wood from shrinking over time and cracking the crystal. It also adds weight to the watch [and offers] additional water resistance that typical wooden watches don't.

The pledging period ends five days from today, and the chosen date isn't arbitrary: It's the birthday of the Stephens brothers' departed grandmother, who suffered from Alzheimer's. Their goal is to start a watch company not just for profit, but to help fund Alzheimer's research.

At press time they were quite close, at $11,450 of a $12,500 goal. You can get in on it here.
