Grande Cosmopolite Tourbillon
What are your watch's functions?
A function or complication is anything your watch does beyond telling the time. Select all that apply.
GMT / Dual Time
Shows a second time zone, usually using an additional hour hand that points to a separate 24 hour time scale on the dial or bezel.
Perpetual Calendar
Displays the date, month, and often the day of the week and year, automatically adjusting for the varying lengths of months and leap years.
Day / Night Indication
Represents the 24-hour cycle, distinguishing between day and night, usually in a sub-dial or section of the watch that changes design or color.
Power Reserve
Indicates how long the watch will run before it needs to be wound again, usually displayed on a gauge or sub-dial on the watch dial or caseback.
World Time
Displays the time in many time zones around the world simultaneously, usually using a rotating dial or bezel labeled with location names.
