WATCHES & WONDERS 2021: Arnold & Son Luna Magna

From inside the Neuchâtel Observatory (Observatoire Cantonal de Neuchâtel) during their Watches & Wonders Geneva 2021 launch, Arnold & Son CEO Bertrand Savary announced the new Luna Magna, featuring not just the brand’s first three-dimensional moon but also, the largest such moon to date – 12mm in diametre, in a wristwatch.

Beneath an off-centred white lacquered dial at 12 o’clock is the rotating sphere made from white marble and aventurine glass. The glittering aventurine dial that forms the background was chosen, of course, to represent the night sky.

The case is in 5N red gold and measures 44mm (thickness of 15.90mm including the crystal), with domed sapphire on both sides. The additional height is obviously necessary given the size of the sphere, but the lugs are short and deeply tapered to make it fit more snugly.

As well as the time and three-dimensional moon on the front, there is a ‘more detailed’ secondary moon phase indicator on the back, which requires a one day correction every 122 years. Changes to the moon phase and time-setting are both done via the single crown.

It is all powered by the new manually-wound A&S1021 movement, developed for the Luna Magna, which beats at 21,600 VPH and has a power reserve of 90 hours. Finishing includes circular graining of the mainplate, blued screws, and Côtes de Genève. The moon phase indicator is circular satin-finished.

Arnold & Son is known for the outsized moon, so perhaps in a way it was only natural that they come up with this idea as well. It is a handsome new addition to their offerings and fits nicely adjacent to the Perpetual Moon collection.

Coming on a blue alligator strap with an 18 kt 5N red gold pin buckle, it is limited to twenty-eight pieces and has an RRP of CHF 43,900 (excluding taxes).
