Hero Watch

The Omnimatrix, nicknamed the Hero Watch, is the Dimension 23 equivalent of the Omnitrix.

Appearance
The Omnitrix's appearance resembles the original Omnitrix prior to its recalibration; however, the interface is blue instead of green and its face has a golden rim instead of gray. It is blue and light blue in color instead of gray.

Functions
Aside from the difference in color scheme, apparently the Omnitrix has its selection of alien DNA in groups of 23, rather than 10, (hence the name of Ben 23).

Like the mainstream version, Ben 23 can transform into a variety of aliens with all of their powers and weaknesses, but must take care when the Omnitrix times out and requires a recharge before transforming again. Since it closely resembles the original Omnitrix, one could assume that it has all the functions and weaknesses of the original model of it's dimensional counterpart.

Other Aliens
These are the aliens that have been named and confirmed to exist.

Trivia

 * According to Derrick J. Wyatt, the Omnitrix doesn't have Molestache, Jetray , Rath , and any aliens that Ben scanned or acquired in some way.
 * Like its other counterpart, the Omnitrix was intended for Max Tennyson but ended up with Ben.
