About this watch

The Longines Master Collection Power Reserve is a stunning timepiece that embodies elegance, precision, and practical functionality. Its luxurious yellow gold case exudes warmth and sophistication, while the beige guilloche dial showcases intricate craftsmanship. The Arabic numeral indexes provide excellent readability, and the feuille hands move elegantly across the dial, protected by a high-quality sapphire crystal. At its heart lies the Longines caliber L602, an automatic movement based on the ETA 2897, boasting a frequency of 28,800 vibrations per hour for precision and reliability. The power reserve indicator allows you to see how much energy is left in the movement, ensuring that your watch is always ready to go. With a date function and water resistance of 30 meters, this timepiece is perfect for everyday wear. The comfort of a high-quality leather strap complements the gold case, providing a soft touch against the wrist.
