About this watch

The Longines Master Collection 40 Chronograph Calendar is a masterpiece of luxury watchmaking, blending traditional craftsmanship with innovative technology. Its stainless steel case and striking black dial exude sophistication, while the guilloche finish on the dial adds a layer of texture. The round case, measuring 40 mm in diameter, sits comfortably on the wrist, making it suitable for various occasions. The Longines caliber L687.2 is a self-winding movement that features a column-wheel mechanism and a longer power reserve, with 25 jewels and a frequency of 28,800 vibrations per hour. This movement offers a full calendar display, indicating the day, date, and month, as well as a chronograph for timing activities with accuracy. The moonphase indicator is a beautiful addition that adds a touch of romance and astronomy to your wrist. With its water resistance of 30 meters, this watch can withstand splashes of water, but it’s not designed for swimming or diving. The Longines Master Collection stands out for its combination of functionality and elegance, making it perfect for anyone who appreciates the finer things in life.
