Twilight watch is meant to remind you of the miracle that is the sunrise. The face of the watch will slowly fade to black throughout the day and keep brightening back up again, it changes about every 20 seconds. It has two polarized disks that rotate to show this effect. Plus it’s made to be a little extra durable, for those that have the tendency to drop their watch in water or just forget to take it off before jumping into a pool. The watch can stay water resistant up to 100 feet under the water.

It’s not entirely waterproof so you will have to be a little extra careful. At least it does have some protection though. You can purchase it for $119.99 from Think Geek.
