Luxury watches are more than just stylish timekeepers. These intricate machines have a multitude of complications that add more functions and tools to the stylish item that can complete an outfit. Our team at T-Bird Jewels has put together a guide to the most common watch complications so that you know the vocabulary before shopping for a new watch.


Professionals in well-maintained jewelry stores will always be able to educate you on different industry terms you may not know, but knowing before entering the store is helpful to the watch-picking process. Below are the definitions of several common watch complications that will be great tools for your daily timepiece.

  • Day-Date: Shows the current day of the week along with the calendar date. This is typically set by twisting the crown in a particular direction.
  • Month: This takes the date complication a step further by displaying the current month.
  • Perpetual Calendar: A complex calendar complication that displays the month, date, day, and year while also keeping track of leap years as well.
  • GMT (Greenwich Mean Time): Fantastic for travelers, a GMT displays a second time zone on a subdial on the face of a watch or with a 24-hour hand. Easily tell what time it is in a different area while maintaining the time of the zone you’re in.
  • Chronograph: A stopwatch function that can be stopped, started, and reset with a click of a button on the side of the watch's case.
  • Moonphase Complication: Used by sailors to gauge the tides once upon a time, a moonphase shows whether the moon is full, new, waning, or waxing in an aesthetically pleasing display on the dial.
  • Power Reserve Indicator: Found in mechanical watches, a power reserve shows how many days or hours of power you have left in the tension of the mainspring and display.
  • Jumping Hour: Shows the hour on an aperture and changes every 60 minutes.
  • Alarm: This allows you to set a specific time for an alarm to go off without messing up the precision of the current time.
  • Minute Repeater: Common in the 18th and 19th centuries pocket watches, a lever will chime the time. This complication is generally now only produced as a nostalgic complication for collectors.
  • Tourbillon: Created by A.L. Breguet, this keeps the watch better balanced to maintain precision and eliminate errors caused by gravity and watch position.
