Arnold & Son Perpetual Moon 41.5mm Platinum Limited Edition Mens Watch Celestial Blue
Ref. 1GLBX.U01A.C200X
The dial is the centrepiece here: a celestial blue base engraved with a radiating stellar motif, beneath which a large mother-of-pearl moon disc sits against a midnight-blue, grained PVD sky. The constellations are hand-painted and treated with Super-LumiNova, as are the painted details on the moon itself. Rhodium-plated hands and applied indices complete the layout. The 41.5 mm platinum case is 11.30 mm thick, with a domed, double-sided anti-reflective sapphire crystal above and an exhibition caseback revealing the in-house A&S1512. This manual-winding calibre runs at 21,600 vph with a 90-hour power reserve. A hand-stitched dark blue alligator strap closes with an 18-carat white gold pin buckle. One of 38 pieces.

Learn more about Arnold & Son
John Arnold was the outstanding English watchmaker of the eighteenth century, and the one who made precision timekeeping practical. Harrison had proved a chronometer could work; Arnold made it manufacturable, and it was Arnold who coined the word chronometer in its modern sense.
His detent escapement and helical balance spring became the basis of marine chronometer design for the next hundred and fifty years. His chronometers went to sea with Captain Cook, and his workshop and his son John Roger Arnold supplied the Royal Navy through the age of sail.
Arnold also made a watch small enough to be set into a ring, presented to George III, which was the technical marvel of its day.
The name was revived in modern Swiss watchmaking and the company now operates from La Chaux-de-Fonds under the same ownership as the movement maker La Joux-Perret.
Modern Arnold & Son keeps to the founder's territory — visible mechanics, tourbillons, dead-beat seconds and true-beat complications, generally with the movement architecture displayed on the dial side rather than hidden behind it.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
No. At 30m it will survive rain and handwashing, but not submersion of any kind.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is hand-wound, so it needs winding every day or two but never a battery.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 90 hours fully wound — enough to sit off the wrist over a weekend and still be running.
Is it a men's or women's watch?
Listed as men's.
