Longines has a particular skill for making complicated watches feel approachable, and the latest Master Collection Chrono Moonphase leans into that strength.
The watch brings together a chronograph, full calendar, moon phase and 24-hour indication, yet its appeal is less about the number of functions and more about how calmly they sit on the dial.
For collectors who like traditional watchmaking with everyday legibility, this is a familiar Longines formula sharpened with careful details.

At a glance
- Longines has introduced a new Master Collection Chrono Moonphase with chronograph, full calendar, moon phase and 24-hour functions.
- The 41mm stainless steel watch uses a silver barley grain dial, navy-blue Arabic numerals, blued steel hands and snail-finished sub-dials.
- It is powered by the automatic L687.5 column-wheel calibre with a silicon balance spring and up to 66 hours of power reserve.
A complicated dial that keeps its composure
The Master Collection has long been one of Longines’ clearest expressions of classical watch design, and this Chrono Moonphase stays close to that brief.
The 41mm stainless steel case is 13.80mm thick, giving the watch enough presence for its layered display without pushing it into oversized territory.
On the right side of the case, chronograph pushers control short-time measurement, reinforcing the watch’s practical side rather than treating the complication as decoration.

The silver dial carries a redesigned barley grain pattern, a traditional texture that adds depth without competing with the indications.
Longines pairs it with snail-finished sub-dials and a sandblasted bezel, so the surfaces change character as the light moves across the watch.
Blue accents bring order to the display
Legibility is often the weak point in watches that combine calendar, chronograph and lunar information, but Longines has used colour and hierarchy to keep the display readable.
The raised navy-blue Arabic numerals give the dial a clear outer structure, while blued steel hands create a visual connection across the different functions.
That blue-on-silver combination is traditional, but it works especially well here because it guides the eye without making the watch feel busy.
The moon phase adds the most romantic element, while the 24-hour indicator and calendar functions keep the watch grounded in daily usefulness.
The L687.5 calibre behind the display
Inside the watch is the exclusive Longines L687.5 automatic calibre, a column-wheel movement chosen for the chronograph’s operation.
It is fitted with a silicon balance spring and offers up to 66 hours of power reserve, a useful margin for a watch that may rotate between weekday wear and weekends off the wrist.
The movement is visible through a transparent case back, which suits the Master Collection’s preference for traditional mechanical appeal rather than hidden engineering.
Longines offers the watch on either a stainless steel bracelet or a dyed alligator leather strap, and both options include a micro-adjustment system.
