The Emotion Lab's Moonwatch doesn't bother with pesky sun-related information a watch normally feeds you. Instead, it's only got one thing on its mind: the phases of the moon. It's not just supposed to turn the watch world on its head, either, as apparently there are folks out there who feel tied to our lunar companion.
From The Emotion Lab:
Moonwatch has been designed to establish a relationship between the moon cycle and a person's emotional states. It's a new concept of time based on nature which invites people to reflect upon and gain a closer understanding of their mood and daily life on earth.
The Moonwatch is just a concept at this time. No word on if the company is planning a future variant of the timepiece that shoots silver bullets, either.
