Longines Master Collection Annual Calendar Automatic 42 mm Silver Barleycorn Dial Bracelet [L2.920.4.78.6]

The Longines Master Collection Annual Calendar Automatic 42 mm [L2.920.4.78.6] stands as a compelling expression of refined Swiss horology, distinguished by one of watchmaking’s most practical and appreciated complications: the annual calendar.

An annual calendar is an advanced mechanical function that automatically recognizes the differing lengths of the calendar year. Unlike a standard date watch, which must be manually adjusted at the end of every month with fewer than 31 days, an annual calendar intelligently differentiates between 30-day and 31-day months. As a result, the wearer needs to correct the calendar only once per year, at the end of February. This balance of mechanical sophistication and everyday convenience places the annual calendar firmly above a simple date complication, while remaining more accessible than a perpetual calendar.

Encased in polished stainless steel, the 42 mm case frames a refined silver dial finished with a traditional barleycorn texture. Elegant Arabic numerals and finely shaped hands preserve the classical identity of the Master Collection, while the calendar display is integrated seamlessly to maintain dial symmetry and legibility.

At the heart of the watch is a Longines self-winding mechanical movement engineered to support the annual calendar complication while delivering a robust 72-hour power reserve. Beating at 25,200 vibrations per hour, the movement combines reliability, precision, and ease of use, and may be admired through the sapphire exhibition caseback.

A scratch-resistant sapphire crystal protects the dial, while the stainless steel bracelet is secured by a triple-safety folding clasp with push-piece opening mechanism, ensuring both comfort and security. Water resistance to 30 metres makes this timepiece well suited for refined daily wear, offering a rare combination of timeless design, mechanical intelligence, and long-term practicality.
