Features

• ChronographComplicated watch with a function for measuring short time periods in addition to its function for permanently displaying hours, minutes and seconds.
• ChronometerLabel given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
• DateThe day of the month, displayed in a window on a watch dial typically at the 3 o'clock or 6 o'clock position.
• Limited editionA series of watches whose production run is determined in advance of production and limited to a set number.
• Small secondsA hand on a sub-dial which tracks seconds; typically it completes a full rotation in one minute.
• Split-Seconds (Rattrapante)In appearance a split-seconds chronograph is only slightly different from a standard chronograph. Its special feature is the additional device which drives a second center-sweep seconds hand called the split-seconds hand. When the chronograph mechanism is activated the two superimposed hands rotate around the dial. If the split-seconds pusher is pressed the split-seconds hand will stop, allowing the user to read the intermediate time. Meanwhile the chronograph seconds hand continues to turn. If the same pusher is pressed again, the split-seconds hand will catch up with the chronograph hand and continue to rotate in perfect unison with it. This operation can be re-peated as many times as desired.
• TachymeterA tachymeter is an instrument for measuring speed. It is a chronograph with a graduated dial on which speed can be read off in kilometres per hour based on 1000 metres distance.
• Transparent case backA transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.
