Here's some interesting context for Hamilton's watch: they recycled the design from a clock they originally made for 2001: A Space Odyssey. Director Stanley Kubrick was notoriously pernickety about design, so what was good for him is good for us.
The titanium Time Player watch has nine tiles on the face, eight of which have counters on, with the remaining one acting like a sliding puzzle, allowing for the time to be set depending on their location. Unfortunately, all this innovation doesn't come cheap—$2,700 to be precise. [Hamilton via Acquire via OhGizmo]
