Blending classical refinement with intricate watchmaking, the Longines Master Collection Chronograph Moonphase L2.962.4.73.2 features a 41mm stainless steel case paired with a blue alligator leather strap. Its silver barleycorn-patterned dial is arranged with painted Arabic numeral hour markers and blue hands, while a scratch-resistant sapphire crystal with anti-reflective coating on both sides ensures excellent clarity. A sapphire crystal exhibition case back offers a view of the movement within, and the triple-safety folding clasp includes a push-piece opening mechanism and fine adjustment system.
