The Omega is a joy to behold and adding the co-axial makes it something special. There are few that mechanically match it though the Haldiman is also a joy. That said, the Sphero is magical to look at and has functions that make it truly a complete watch. It actually is a great travel (2 timezone) watch. Functionality, construction, eye popping tourbillion, finishing all favor the Sphero in my opinion.
