Master Collection 42mm Blue Dial Leather

A sunray blue dial carries the full calendar workload on this Longines Master Collection, reference L27734920. A column wheel chronograph, moon phase, month and day indicators, and a date ring on the outer rim of the dial share the face with silvered polished hands and applied indexes. The stainless steel case measures 42 mm across and 14.20 mm thick, with a fixed bezel.

Inside, the self-winding L687.5 calibre beats at 28,800 vibrations per hour and stores up to 66 hours of power, visible through the sapphire case back. A sapphire crystal covers the dial, and water resistance is 30 meters. The 21 mm strap pairs alligator leather on top with calf leather underneath, closed by a triple safety folding clasp with push-piece opening. A dressy, full-featured watch for those who like complications.
