Longines Master Collection Annual Calendar

Longines launched the Master Collection in 2005 and since then this iconic watch collection has enjoyed an undeniable level of success. Over the years, The Longines Master Collection has been enhanced by new features, but has never lost sight of the timeless classical elegance that is emblematic of the brand, and that contributes to its global success. Longines now offers an annual calendar as part of its Master Collection, controlled by a new mechanical movement.

Combining classical elegance with excellence, the models from The Longines Master Collection featuring an annual calendar contain the new automatic L897 caliber in a stainless-steel case measuring 40 mm in diameter.

With 64 hours of power reserve and the annual calendar displayed at 3 o’clock, the movement can be viewed through the transparent case back. The rhodium plated or blued steel hands jump off the black or silver barleycorn or sunray blue dial.

These elegant timepieces are complimented by a steel bracelet or black, brown or blue alligator watch strap, all fitted with a folding safety clasp.
