Chronograph
Split-Seconds Chronograph
Date
Chronograph watches can measure and display elapsed time. Usually three subcounters on the dial display the elapsed seconds, minutes and hours.
Split-seconds chronographs can measure intermediary time thanks to another second hand which is able to catch up with the other running hand if needed.
The date is a small window on the dial which indicates the day of the month (between 1 and 31).
