About this watch

The Longines Master Collection 40 Chronograph Calendar L2.673.4.71.6 is a masterpiece of watchmaking excellence, blending elegance, functionality, and craftsmanship in perfect harmony. This stunning timepiece is designed for those who appreciate the finer things in life, with a round stainless steel case featuring a polished sunburst finish that catches the light beautifully. The silver dial is adorned with stick and dot indexes, ensuring readability, while the Feuille hands glide smoothly across the face, giving it a touch of sophistication. The chronograph functions are clearly displayed, making it easy to track time with precision. One of the standout features of this watch is its moonphase indicator, adding a unique touch to its charm. Powered by Longines' own caliber L678.2 movement, celebrated for its reliability and performance, this automatic timepiece boasts a 42-hour power reserve and operates at a frequency of 28,800 vibrations per hour. With its full calendar functionality, indicating the day, date, and month, you have all the information you need right at your fingertips. The watch's comfort is also noteworthy, with a height of 14.30 mm and a lug width of 21.00 mm, making it relatively slim and easy to wear even for extended periods. Its durable stainless steel bracelet is adjustable, ensuring a snug fit on any wrist. While the watch is rated for 30 meters of water resistance, it's essential to remember this isn't a diving watch, but it can withstand splashes and brief immersion, making it perfect for everyday wear.
