LONGINES MASTER COLLECTION CHRONO MOONPHASE

The LONGINES MASTER COLLECTION CHRONO MOONPHASE is an exquisite timepiece that harmoniously blends classic elegance with advanced horological complications. Encased in polished stainless steel or 18k rose gold, the watch features a refined 40mm or 42mm diameter case, complemented by a scratch-resistant sapphire crystal with anti-reflective coating. The silver, black, or deep blue dial showcases a sunray-brushed finish, adorned with Roman numeral or diamond hour markers and blued steel hands for a timeless aesthetic.

At its heart lies the self-winding L687.4 column-wheel chronograph movement, offering a 54-hour power reserve. The watch boasts a chronograph function with 30-minute and 12-hour counters at 3 and 6 o’clock, respectively, while a moon phase indicator at 6 o’clock adds poetic complexity. A date subdial at 12 o’clock enhances practicality. The moon phase disc, set against a starry sky, completes a full cycle every 29.5 days with remarkable precision.

The transparent case back reveals the meticulously decorated movement, featuring perlage and blued screws. Water-resistant to 50 meters, the watch is paired with an alligator leather strap or stainless steel bracelet, secured by a double folding clasp. This masterpiece embodies LONGINES’ 190-year heritage of Swiss craftsmanship, merging technical prowess with understated luxury.
