Arnold & Son has unveiled a new version of the HM Perpetual Moon with a steel case and blue guilloché dial. This watch with one of the biggest moonphase apertures on the market, is part of the Arnold & Son Royal Collection of timepieces inspired by watches created in the early part of John Arnold’s life, a tribute to traditional watchmaking and classical decorative arts.

The exceptional perpetual moonphase indication of this watch is a marvel in many ways. From the aesthetic side, the 29 mm moonphase disc, which runs from 10 to 2 o’clock on the dial, reveals one of the largest moons on the market – with a diameter of 11.2 mm for the moon alone. Additionally, this large moon is one of the most visually stunning recreations of the moon because it is a three-dimensional sculptured moon that was first hand-engraved and then duplicated for the series. The sculptured moon is then inserted into the guilloché disc.

It houses the exclusive Arnold & Son mechanical hand-wound movement, the calibre A&S1512. This calibre was especially developed for this model with the objective of offering a uniquely precise, big and three-dimensional moonphase. The calibre is also equipped with a double barrel to yield 90 hours of power reserve.

Besides all these technical features, the movement receives the attention and care worthy of a royal timepiece, such as manually chamfered bridges with polished edges, Côtes de Genève rayonnantes and fine circular graining, circular grained wheels, and blued screws with polished and chamfered edges.
The HM Perpetual moon measures 42 mm in diameter in its classically elegant stainless steel case. It comes with an exquisite hand-stitched alligator strap.
