“This collaboration embodies both rarity and emotion. The moon and turquoise express two eternal forces—mystery and vitality—brought together in a case of pure gold. We proudly offer our collectors this unique edition that bridges fine art, craftsmanship, and celestial inspiration.”
—Tim Richardson, Co-CEO and Co-Founder of Exquisite Timepieces

Astronomical
Arnold & Son has long been recognised for pioneering the integration of fine stones and celestial materials such as meteorite, pietersite, and turquoise. Each natural element, shaped by millennia, becomes a canvas for horological expression.
The Luna Magna’s signature astronomical moon—a 12 mm, three-dimensional sphere—rotates in harmony with the lunar cycle. In this edition, the moon is composed of half turquoise and half Cacholong opal, representing the balance between Earth and sky. The 44 mm 5N red gold case enhances this dialogue of light and texture, producing a warm and radiant presence on the wrist.
Created exclusively for Exquisite Timepieces, this edition draws on turquoise’s rich cultural and spiritual legacy. Venerated by ancient civilisations for its protective and healing properties, turquoise has long symbolised a bridge between the celestial and terrestrial worlds. Through this limited release, Arnold & Son and Exquisite Timepieces pay tribute to both the stone’s heritage and the artistry of haute horlogerie.

An endless mechanism
At its heart, the Luna Magna houses the A&S1021 calibre, a manual-winding movement entirely developed and manufactured in-house. Offering a 90-hour power reserve, the movement also features a secondary moon-phase display on the reverse side for precise astronomical adjustment.
Produced in a strictly limited edition of five pieces and available exclusively through Exquisite Timepieces, the Luna Magna Red Gold Turquoise stands as a radiant celebration of craftsmanship, rarity, and partnership—a celestial masterpiece brought to life in gold.
