About this watch

The Longines Master Collection 40 Moonphase, model L2.909.4.51.6, is a masterpiece of luxury watchmaking. This elegant timepiece boasts a classic design with a black guilloché dial adorned with Roman numerals, exuding timeless appeal. The round stainless steel case (40mm diameter) and sleek design make it versatile for various occasions. At its heart beats the self-winding Longines caliber L899.2 movement, featuring a moon phase indicator and date function. This automatic movement is based on the reliable ETA A31.L91, with a frequency of 25,200 vibrations per hour and a power reserve of 64 hours. The watch's durability is ensured by its stainless steel case, resistant to corrosion and scratching. Protected by sapphire crystal, the stunning guilloché dial remains vibrant and clear. The comfortable stainless steel bracelet features a deployment clasp, adding an extra layer of sophistication. With a water resistance rating of 30 meters, this watch is suitable for light splashes but not designed for aquatic adventures. The Longines Master Collection 40 Moonphase is an investment in style and craftsmanship, available at authorized retailers or luxury boutiques.
