About this watch

The Longines Master Collection Small Seconds XL is a masterpiece of horology that combines elegance with functionality. Founded in 1832, Longines has built a reputation for producing high-quality timepieces that reflect a commitment to precision and style. The Master Collection, where this watch belongs, embodies the brand's philosophy of blending tradition with innovation. With its classic design and modern features, this watch is perfect for those who appreciate the finer things in life. At the heart of the Master Collection Small Seconds XL lies the Longines caliber L512, a handwound movement that showcases the brand’s dedication to precision. This movement is an adaptation of the well-known ETA 6498-1, recognized for its reliability and accuracy. The watch features a round case measuring 47.5 mm in diameter, crafted from stainless steel, giving it a robust yet refined look. The beige dial offers a soft contrast to the bold Arabic numerals that mark the hours. Equipped with sapphire glass, this timepiece is designed to withstand daily life while maintaining crystal-clear visibility. The open case back allows you to admire the intricate workings of the Longines caliber L512. With a lug width of 25.00 mm and a stainless steel bracelet, the watch strikes the right balance between presence and wearability. Water resistance of 30 meters makes it suitable for everyday wear, but not designed for swimming or diving. The handwound movement offers a power reserve of 46 hours and precise timekeeping with a frequency of 21600 vibrations per hour.
