Avigation BigEye 41mm Petroleum Dial

A titanium case and a petroleum-colored dial set the Longines Avigation BigEye, L28161932, apart in the Heritage Avigation line. At 41 mm, it uses a fixed titanium bezel, painted Arabic numerals, black hands and luminous markers. A 60-second subdial sits at 9:00, while the chronograph runs a central seconds hand with a 30-minute counter at 3 and a 12-hour counter at 6.

Caliber L688 is self-winding, beats at 28,800 vibrations per hour and holds about 66 hours. The sapphire crystal and screw-down case back give 30 meters of water resistance. The case is 14.5 mm thick, with a 20 mm leather strap and a pin buckle.
