Watch Complications are anything that is added to a watch other than hours, minutes, seconds and that includes simple additions such as Day and Date Windows. The list is pretty lengthy, but let’s take a look at some of the commonly seen complications.
Triple Calendar The triple calendar takes the Day + Date complication one step further by adding the month of the year to the Day-Date display. Now, in addition to showing the day of the week and the date of the month, the display will also showcase the specific month.
Annual Calendar Staying with the theme of adding to the existing complication, the Annual Calendar adds a new element to the calendar function which already gives the day, the date and the month, and then adds the year to it. This complication does not take into account leap years.
The ubiquitous Alarm function needs no explanation. The only surprise is the knowledge that such a common feature is a complication.
A repeater is a complication in a mechanical watch or clock that audibly chimes the hours and often minutes at the press of a button. There are many types of repeater, from the simple repeater which merely strikes the number of hours, to the minute repeater which chimes the time down to the minute, using separate tones for hours, quarter hours, and minutes. They originated before widespread artificial illumination, to allow the time to be determined in the dark, and were also used by the visually impaired. Now they are mostly valued as expensive novelties by watch and clock enthusiasts. Repeaters should not be confused with striking clocks or watches, which do not strike on demand, but merely at regular intervals.

Minute Repeater Complication A common complication on vintage watches the Minute Repeater is now only seen on modern watches as an attempt to increase the cost and collectability of the pieces. The function causes the watch to chime when a mechanical lever on the side of the case is used.
A clinometer or inclinometer is an instrument for measuring angles of slope (or tilt), elevation or depression of an object with respect to gravity. It is also known as a tilt meter, tilt indicator, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, declinometer, and pitch & roll indicator. Clinometers measure both inclines (positive slopes, as seen by an observer looking upwards) and declines (negative slopes, as seen by an observer looking downward) using three different units of measure: degrees, percent, and topo (see Grade (slope)#Nomenclature for details). Astrolabes are inclinometers that were used for navigation and locating astronomical objects from ancient times to the Renaissance.
