Quick TakeThis Longines Master Collection beauty? Total package! Check out that moon phase complication nestled within the chronograph's hour counter–classy touch. The silver "barleycorn" dial, blued steel hands, against those bold Arabic numerals, create a great face. Flip it over, there is a L687 automatic movement doing its thing through the transparent sapphire case back. It's a great size, solid on the wrist, but won't control your arm. This watch is a perfect daily go to.

DescriptionThe L2.773.4.78.3 features a circular stainless steel enclosure, measuring 42.00 mm in diameter and 14.20 mm in height, with a lug-to-lug span of 49.50 mm, and 21mm lug width. A transparent case back, constructed from scratch-resistant sapphire, reveals the inner mechanisms, mirroring the sapphire crystal protecting the dial. The assembly has an aggregate mass of 102.9 g and achieves a pressure resistance equivalent to 3 bar. The dial surface is finished in a silver "barleycorn" texture, displaying time via painted Arabic numeral indices and blued steel hands.

This timepiece incorporates a self-winding mechanical L687 caliber. The mechanism oscillates at a frequency of 28,800 vibrations per hour, accumulating a power reserve of approximately 66 hours. Beyond standard timekeeping, functions encompass a small seconds subdial integrated with a 24-hour display, a date indicated by a crescent-tipped central hand, and a moon phase aperture. The chronograph, controlled through a column wheel, includes a central 60-second counter, a 12-hour counter within moon phase at 6 o'clock, plus 30-minute counter with companion day/month apertures at the 12 o'clock marker. Securement is a brown alligator strap with safety folding clasp.
