Longines has long been celebrated for its dedication to horological excellence, and the Master Collection represents the very heart of this heritage. It is a line where traditional elegance meets modern precision, making it a favorite for those who appreciate the finer details of watchmaking. This 40mm stainless steel model features a striking sunray blue dial protected by scratch-resistant sapphire crystal. Powered by the reliable L888 automatic movement, it offers a glimpse into its mechanical heart through a transparent case back, finished with a secure triple safety folding clasp.
