Your perception of time grows shorter as you get older. A week seems to happen in a blink of an eye. Then months. And then, just like that, a year has pass. Time is precious.

So naturally, you'll want to use your time more efficiently. This rotating disc on Mr Jones' Average Days watch takes 24 hours to make a full lap, and it spins to reveal the most common activity for a given hour, and the average time spent doing it. Perfect for if you want to know how much time you're wasting.

The folks at Mr Jones borrowed research and data from the Centre For Time Use Research to create this unique, but accurate, timepiece. [Mr Jones Watches via Holycool]
