The Longines Master Collection Moonphase is a refined luxury timepiece featuring a 38.5mm stainless steel case with a sunray-brushed silver dial, adorned with 12 brilliant-cut diamond hour markers for elegant sparkle. The iconic moonphase complication at 6 o’clock displays lunar phases with a blue sky, golden stars, and a detailed moon disc—enhanced by a date ring around its perimeter. Powered by the automatic L899 caliber (based on ETA A31.L01), it offers a 45-hour power reserve and COSC-certified chronometer precision. The watch includes a polished stainless steel bracelet with brushed center links and a secure double-fold clasp. Water-resistant to 30m, it balances classic Haute Horlogerie aesthetics with everyday wearability. Ideal for formal events, business settings, or sophisticated daily use, this model exemplifies Longines’ heritage of Swiss elegance since 1832. The clean Arabic minute track, blued-steel hands, and subtle ‘Automatic’ and ‘Swiss Made’ inscriptions underscore its authenticity and craftsmanship.
