ABOUT THE MOVEMENT
Perfecting the art of beautification, Arnold & Son created a timepiece that strikes the perfect balance between aesthetics and complex timekeeping. This timepiece is the Arnold & Son Perpetual Moon. The Perpetual Moon features one of the largest moon phase indicators on a wristwatch. Running this diamond of a timepiece is the A&S1512 manual winding movement. One of the unique features of the A&S1512 is that it also displays a moon phase indicator on the back of the movement. Pointed by a central hand, this sub-dial is fitted right beside the balance wheel. The A&S1512 also offers a power reserve of approximately 90 hours while vibrating at a frequency of 21,600 vph.
