The Longines Master Collection Retrograde, which houses an ETA calibre developed and produced exclusively for Longines, is a watch line with sleek, elegant lines and a genuine homage to the maison. It offers retrograde functions (day, date, seconds, 24-hour second time-zone) and a self-winding movement, embodying avant-garde mechanical horology while being simple to operate. Today, Longines has fitted this exclusive movement into a new, sleeker case, and the range also includes a variant with a power-reserve indication and three retrograde functions (day, date, 24-hour second time-zone).
