A sophisticated luxury timepiece from Longines' iconic Master Collection, featuring a white guilloché dial with applied Arabic numerals, blue steel hands, and three subdials for chronograph functions (30-min counter at 3 o'clock, 12-hour counter at 6 o'clock, small seconds at 9 o'clock), plus a moonphase display at 6 o'clock with date window integrated into the 12-hour counter. The watch includes an annual calendar complication showing month (APR), day (5), and year (2019) via dedicated subdials—indicating this is likely a promotional or display model. Crafted in stainless steel with 18K yellow gold bezel, crown, and center links, it showcases elegant two-tone design. The automatic movement (Caliber L678/L679 family) ensures precision and reliability. Water-resistant to 30m, it features a sapphire crystal and a polished/brushed bracelet with deployant clasp. Ideal for formal business settings, weddings, or upscale evening events where refined horology meets timeless elegance. Its balanced proportions (approx. 42mm case) suit men’s wrists comfortably, combining heritage craftsmanship with modern functionality.
