Wonder where your plastic water bottle goes after you toss it in the recyling bin? Well, we rescued many of them to make some of our best Mens watches, yet. These straps use rPet® or recycled polyethylene terephthalate. But, you don't have to know that. All you have to know is that these watches are strong and durable, just like the bottles were in their previous life. Plus, they look really cool.
