Official description

Available for the first time in steel, the Reference 5905 self-winding flyback chronograph with Annual Calendar radiates a resolutely sporty look. The rhythmic dial features an elegant and casual "sunburst" olive green color. The integrated bracelet is enhanced by contrasting polished and satin finishes. Thanks to the vertical disk-type clutch, the central chronograph seconds hand can be used as a permanent (running) seconds display. The patented Annual Calendar automatically takes account of 30- and 31-day months, requiring only one correction per year, on March 1st.
