Longines Master Collection Chronograph Moonphase L26734783
The Longines Master Collection Chronograph Moonphase Ref. L2.673.4.78.3 is a sophisticated and classically elegant timepiece that represents the pinnacle of Longines’ watchmaking expertise, combining a full calendar, chronograph, and moonphase complication in a beautifully balanced and highly legible layout. This 40mm stainless steel case, measuring 14.3mm in thickness with a 46.7mm lug-to-lug and 21mm lug width, houses a silver “barleycorn” dial with a distinctive textured finish that catches the light, complemented by blued steel hands and painted Arabic numeral hour markers for a refined, traditional aesthetic . The dial is a masterclass in functional elegance: a central half-moon hand indicates the date around the outer perimeter, while the 30-minute chronograph counter at 12 o’clock integrates day and month windows, the 12-hour counter at 6 o’clock houses the moonphase aperture, and a small seconds sub-dial at 9 o’clock includes a 24-hour AM/PM indicator . At its heart beats the in-house automatic Caliber L687, a self-winding mechanical movement operating at 28,800 vibrations per hour with a column-wheel chronograph mechanism and an impressive 66-hour power reserve . The watch is completed by a brown alligator leather strap with a triple-safety folding clasp and push-piece opening mechanism, offering both security and refined comfort, and is water-resistant to 30 meters (3 bar) with a scratch-resistant sapphire crystal and transparent caseback revealing the movement’s finishing . Presented in Longines’ signature packaging with a five-year warranty, this reference represents the perfect synthesis of Swiss horological tradition, sophisticated complications, and accessible luxury, making it an exceptional choice for the discerning collector who appreciates classical watchmaking with practical everyday functionality.
