About this watch

The Longines Master Collection Small Seconds embodies the essence of luxury watchmaking with its refined aesthetics and practical features. At the core is the Longines caliber L512, a hand-wound movement that pays homage to traditional watchmaking while providing modern reliability. The case is crafted from high-quality stainless steel, elevating its durability and luxurious feel. With a diameter of 47.50 mm, this watch makes a bold statement while remaining comfortable on the wrist. The black dial features Roman numeral indexes and Feuille hands, adding classic sophistication and refined readability. Protected by a sapphire crystal, the dial is resistant to scratches, ensuring pristine wear. Pairing with a leather strap enhances its overall appeal, suitable for all-day wear. With a water resistance of 30 meters, it can withstand splashes and brief immersion in water, but not rigorous aquatic activities. The Longines Master Collection Small Seconds is a stunning watch that balances elegance, functionality, and craftsmanship, making it an ideal choice for luxury timepiece enthusiasts.
