Quick TakeThis Longines Master Collection Moonphase is where old-school charm punches the clock alongside some serious watchmaking muscle. The silver dial and sharp Roman numerals, paired with those blued steel hands, scream classic, but that 42mm case, packed with a self-winding L687 that shows day, date, month, moonphase and chronograph? That is some high-octane. It's a detailed, complicated automatic watch that still feels clean.

DescriptionThe L2.773.4.71.2 model features a round, stainless steel enclosure with a diameter of 42.00 mm and a thickness measuring 14.20 mm. The distance between the lugs is 21 mm, while the complete lug-to-lug span extends to 49.50 mm. Total mass comes in at 102.9 grams. Sapphire crystal, treated with multi-layered anti-reflective coatings, protects the dial surface, and the transparent case back. It provides resistance to water pressures equivalent to 3 bar. The unit includes a silver colored face, with roman numeral hour markers.

The timepiece is controlled by the L687 caliber automatic movement. This mechanism operates at 28,800 vibrations/hour and features a monocrystalline silicon balance-spring, producing a power reserve of approximately 66 hours. Functionality encompasses time display (hours, minutes, seconds), with the date displayed via a crescent-tipped central hand. A 24-hour display is integrated into the small seconds subdial, moon phase. The chronograph incorporates a central 60-second hand, along with 12-hour and 30-minute counters. A Blue alligator strap accompanies.
