Our Navy SEAL collection would not be complete without a chronograph. The further development of our 3500 series, the 3581.BO features a chronograph complication with three sub dials on a black-in-black dial. The timer is started or stopped with the upper pusher above the crown, while the lower pusher resents the measured time. Luminox Light Technology allows for at-a-glance visibility in dark circumstances.
