Longines’ quartz chronographs fitted with calibre L538
or L541 show the hours, minutes, seconds and the date.
As far as concerns the chronograph functions, these
models can be used to time events that last up to 30
minutes (cal. L538) or 12 hours (cal. L541), and show
the results to a 1/10th of a second.
