About this watch

The Longines Master Collection Power Reserve, reference L2.666.4.51.5, is a masterpiece of watchmaking that embodies the perfect balance between technical innovation and timeless aesthetics. The black guilloche dial with intricate pattern catches the light beautifully, giving the watch a dynamic quality. The 42 mm stainless steel case feels robust yet refined, suitable for various occasions. The sapphire crystal offers excellent scratch resistance, while the feuille hands add a vintage flair to the design. At its heart is the Longines caliber L602, an automatic movement with 21 jewels and a frequency of 28,800 beats per hour, offering reliable and accurate timekeeping experience. The power reserve indicator adds a layer of practicality, while the date function at 6 o'clock is easy to read without cluttering the dial. With a water resistance rating of 30 meters, this watch can withstand occasional rain but isn't designed for diving. It comes with a high-quality leather strap that feels incredibly comfortable on the wrist and weighs in at just the right amount, making it an excellent choice for long wear.
