Listen NASA, we understand that 'kind of' being there in person is a better way to explore Mars. But with your recent budget cuts you can save hundreds of millions of quid by just ordering and passing out a few of these Cyrus Klepcys Mars watches to your scientists.
In the lower right corner of the watch's face they'll find a miniature version of the red planet that rotates at the same speed as the real thing. Taking slightly longer than the Earth to make a full rotation at 24 hours, 37 minutes and 22 seconds. And in addition to red accents all over the watch's face, it also bears an image of the famous Martian face as captured by the Viking 1 explorer back in 1976.
Sadly, Cyrus only intends to produce 66 limited edition pieces of this design. So while they won't be as expensive as the Spirit or Opportunity rovers, they're probably still going to be outside your current budget restraints. [Cyrus via Unique Watch Guide]
