Longines Master Collection Moonphase Automatic Silver Barleycorn Dial Brown Alligator Strap 40 mm [L2.909.4.78.3]

The Longines Master Collection Moonphase [L2.909.4.78.3] Automatic is a refined showcase of Swiss mechanical mastery and classic complication, elegantly balanced in a 40 mm stainless steel case. Its beautifully textured silver barleycorn dial creates depth and character, serving as the backdrop for the integrated moonphase display and discreet date function, which together offer both practical utility and horological distinction. 

Polished hands and applied indexes provide crisp legibility, while the traditional moonphase indication adds a timeless complexity that elevates this model beyond everyday timekeeping. The watch is mounted on a brown alligator leather strap with a triple safety folding clasp and push-piece opening mechanism, ensuring comfort and confidence on the wrist. 

Driven by a self-winding mechanical movement with an approximate 72-hour power reserve, this Moonphase model combines enduring performance with classic aesthetics. Protected by a scratch-resistant sapphire crystal and water resistant to 3 bar (30 m), the Master Collection Moonphase [L2.909.4.78.3] is a compelling choice for those who value refined Swiss watchmaking tradition with everyday functionality.
