Longines Master Collection Annual Calendar Automatic Silver Barleycorn Dial Stainless Steel Bracelet 40 mm [L2.910.4.78.6]

The Longines Master Collection Annual Calendar [L2.910.4.78.6] Automatic is a distinguished Swiss timepiece that combines classic aesthetics with the practical sophistication of an annual calendar complication in a versatile 40 mm stainless steel package. Designed for collectors and enthusiasts who appreciate both mechanical refinement and everyday usability, this model features a beautifully textured silver barleycorn dial that enhances visual depth while maintaining a timeless, elegant appearance.

The standout feature of this model is the annual calendar display, which intelligently accounts for the varying lengths of months (30 or 31 days), requiring adjustment only once per year at the end of February — a hallmark of advanced mechanical watchmaking. The date window is harmoniously integrated into the layout, and polished hands and applied indexes ensure excellent legibility in all lighting conditions.

At its core beats a self-winding Swiss mechanical movement with a monocrystalline silicon balance-spring, delivering reliable accuracy and an up to 72-hour power reserve — an impressive performance benchmark for mechanical watches in this category. The integrated stainless steel bracelet, finished with a secure folding clasp, complements the case with refined continuity, making the watch suitable for both formal occasions and daily wear.

Protected by a scratch-resistant sapphire crystal and rated to 3 bar (30 m) water resistance, the Master Collection Annual Calendar [L2.910.4.78.6] is the perfect embodiment of Longines’ commitment to classical design, technical sophistication, and enduring quality.
