A dual time clock face which displays the local time and Zulu time or an offset from Zulu (GMT) time.  Either can be displayed as the primary time.  This is a highly customizable version of Aviation Time.

Aviation Dual Time also has options to: 
  Display steps (in place of the second time zone)
  Display or hide watch notifications
  Display or hide the current battery charge
  A seconds indicator (only on round watch faces)
  On compatible watches, an option to display the current weather in lieu of the current battery charge
  Always on Display show local and selected Zulu time.
  
Aviation Dual Time also has multiple color options for the main time, secondary items, the background color, and shadows for the primary time. If selected, it displays either a clock oe an 'A' if an alarm is set and will display an encvelope or an 'N' if you have any notifications.

For newer, touch screen watches some new tricks are added.  If you press and hold the top 3rd of the screen, it opens up Garmin's battery manager or weather app (depending on what you have displayed).  If you press and hold the middle third, it opens up Garmin's schedule display.  Press and hold the bottom third displays Garmin's Step app.  There is an option to block the press and holds from happening, too.
