Longines 2025 Annual Calendar. Longines master collection, a classic swiss timepiece, perfectly illustrates the longines ethos of timeless elegance through watchmaking expertise. With a dial aesthetic that is typical of the masters collection, the annual calendar function, displayed at 3 o’clock, automatically registers different month lengths, so provided you keep it running, you won’t have to make any adjustments to it.

The master collection has a wide variety of complications, from power reserve displays to calendar chronographs with moon phase and more, but these new models are the first for longines to have an annual calendar. Hours, minutes, seconds, month and date by annual calendar.
