1 JUMP­ING HOUR is when the hour hand jumps from one hour marker to an­other, in­stead of sweep­ing around the dial. Sim­i­larly, there are jump­ing min­utes and jump­ing sec­onds.

2 DATE COM­PLI­CA­TION may take the form of a sim­ple date win­dow, a day-date dis­play or com­pli­ca­tions such as an an­nual cal­en­dar or even a per­pet­ual cal­en­dar.

3 CHRONO­GRAPH is es­sen­tially a stop­watch on a wrist­watch. A fly­back chrono­graph en­ables a sin­gle press to re­set and im­me­di­ately restart a lap. A rat­tra­pante or split-se­cond chrono­graph can time two dif­fer­ent laps at once.

4 DUAL Time zone has two dif­fer­ent time zones shown on a dial. This is es­pe­cially use­ful for those who of­ten travel and need to be aware of lo­cal time as well as the time back home.

5 AS­TRO­NOM­I­CAL com­pli­ca­tions vary from the moon phase, which shows the moon cy­cle, to an equa­tion of time, which tracks so­lar time, to a plan­e­tar­ium model, which keeps track of plan­e­tary move­ment.

6 RE­PEATER is a chim­ing mech­a­nism that au­di­bly tells the time when­ever a pusher is pressed. It is one of the old­est com­pli­ca­tions.

7 TOURBILLON (see the watch 101 sec­tion in the pre­vi­ous page) can now ap­pear in even more com­plex forms, in­clud­ing dou­ble- and triple-axis tour­bil­lons, the fly­ing tourbillon as well as brand-spe­cific in­no­va­tions.
