Officine Panerai Luminor Chrono Daylight 44mm PAM 00250 and PAM 00251

Daylight. While Sylvester Stallone wears a Panerai in the 1996 disaster movie Daylight, Panerai's use of the name daylight initially referred to Panerai watches with a white dial. Today the name is used in conjunction with Panerai's Luminor based tradition chronograph watches.

The traditional chronograph design, consist of a watch with a stop watch function. The stop watch function uses the main second hand to measure seconds and one or two sub-dials to measure minutes or hours. These watches feature two buttons, one to start and stop the stopwatch function, and the other one to reset the main second hand and sub-dials all back to zero.

Today, we have more complicated chronographs, like the single button flyback or splits seconds chronographs, but must chronograph still follow the traditional design.
