True Moon

Since the dawn of time, the moon has been a constant source of inspiration for scholars, scientists, poets, lovers… and watchmakers. This fascinating satellite of our blue planet is known to exercise an influence on both tides and times, and lunar cycles are sometimes even credited with affecting moods and even madness! Despite scientific advances, there is something inexplicable about the mysterious visible and invisible aspects of this celestial luminary that continues to intrigue and incite us to contemplate its constant transformations. Horologists have long since found ways of reproducing moon phases on a watch dial, although such displays have always been somewhat inaccurate, either in terms of their visual depictions or their actual precision.  Time and space In presenting the True Moon watch, Arnold & Son pursues its mission of providing a realistic representation of our grand cosmic clock, already expressed through other creations including the groundbreaking True North presented in 2004. Like its predecessors, this stunning new model is entirely keeping with the Arnold & Son spirit of discovery, which originated in the 18th century quest for longitude and has since extended beyond maritime horizons to encompass exploration and navigation on land and even in the air.  The next step was of course space, a vast territory that Arnold & Son had already begun to chart with the creation of innovative perpetual calendar and equation of time mechanisms. While the latter revolved around enabling a correct calculation of true solar noon, the True Moon is powered by a world-first mechanism capable of keeping precise track of the true waxing and waning faces of the nocturnal heavenly body. To achieve this unprecedented feat, it is calculated on the exact synodal period corresponding to 29 days, 12 hours and 44 minutes. In keeping with its time-honoured philosophy, Arnold & Son once again succeeds through its new True Moon in transforming the most complex mechanical and scientific principles into poetry, romance and fascination. A truly astronomical achievement!
