Longines Longines Master Collection

The L687 by Longines stands out as an impressive calibre, built upon ETA's robust and reliable 7751 movement. This calibre boasts a multitude of complications, including hours, minutes, and small seconds with a 24-hour indicator positioned at nine o'clock. It also features a date indicator encircling the dial, a column wheel chronograph mechanism with a central 60-seconds hand, a moon phase display with a 12-hour counter at six o'clock, and a 30-minute counter alongside day and month displays at 12. Operating at 28,800 beats per hour, it offers a power reserve of 66 hours. The movement showcases refined components, with elegant decorations like perlage and a rotor adorned with intricate wave patterns and gold engraving of the Longines brand name.
