The QTR-24 is a 12 and 24 hour format clock which was made before I was even born (i.e. around 40 years ago).  Normal clock movement (hours, minutes, seconds) on this unique timekeeping device is represented in the classical 12 hour format, while an outer ring depicts time in a 24 hour format. Furthermore, the first 12 hours are shown in white to depict daylight and the other 12 in black. 

As the name suggests, the QTR-24 World Clock also features a world time read out.  Of course, the current name and format for world time, something us DXers talk about all the time and refer to on QSL cards, logging programs, clusters and the like, is called Universal Time Coordinate (UTC).  It’s also been known as Greenwich Mean Time (GMT) and the military term ZULU (Z).  All world time on the QTR-24 is represented in a 24-hour format based upon the global starting point in Greenwich, England (UK).

On the QTR-24, the outer-most perimeter of the clock face has the names of the major cities throughout the world in each of the 24 global time zones.  As the 24 hour ring passes a group of cities, you can easily see their UTC time and a day/night indication.  I have found this is always a great conversation starter during a QSO with an op on the other side of the world!

On this note, the time in any city or time zone can be, at the same time, synchronized with your own local time on a 24 hour basis.  After the initial setting, as the clock runs, the Time Zone Hour Disc progresses automatically, thus maintaining the right setting and showing correct time on all indicated locations without any further tweaking.

The QTR-24 has three adjustments on the rear.  One for time (basic movement adjustments), one for the 24-hour ring, and one for fine-time adjustment.
