COSC Chronometer. Aviation Soul.

The Longines Spirit Black Dial (L3.410.4.53.6) is built for those who demand more than accuracy — they demand certified accuracy. A COSC-certified chronometer, the Spirit carries five stars on its dial as proof of its precision, meeting the Swiss Official Chronometer Testing Institute's rigorous standards of −4/+6 seconds per day. Inspired by Longines' rich aviation heritage, it wears that precision with confidence.
