When the moon becomes part of time
The Secunda Lunaris M combines classical horological craftsmanship with an extraordinary, hand-painted interpretation of the moon phase. On the finely silver-plated dial , the time, small seconds, date, weekday, and moon phase display merge into a harmonious composition of timeless elegance. The mysterious character of the moon becomes the defining design element of this exceptional precision pendulum clock.
The moon immortalizes itself in a dial. next to a calendar, a hand painted moon phase.
Special attention is also drawn to the elaborately domed, polished, and heat-blued Breguet hands, which add further depth and sophistication to the dial.
Finely ground, bright nickel-plated plates create an elegant contrast to the gold-plated gear wheels.
During winding, a so-called maintaining power mechanism ensures continuous power transmission and guarantees uninterrupted operation of the clock.
Exceptional precision is additionally ensured by the compensation pendulum with Invar rod and compensation tube, as well as the integrated aneroid capsule instrument with barometer display.
The Secunda Lunaris M is more than a clock — it is a fascinating interplay of mechanics, aesthetics, and astronomical inspiration, bringing a unique atmosphere to any room.
