ince its debut in 1999, the Lunar Chronograph has represented a rare and harmonious union of complications: Chronograph, date, and moon phase brought together in a balanced, architectural composition. It has always stood for classical Swiss watchmaking with a bold, independent spirit. With the Aurora, that spirit evolves.

The transformation begins with the dial. Fully CVD-coated, it shifts from deep green to vivid blue depending on the light, reminiscent of the aurora borealis that inspired its name. The effect is subtle yet captivating, turning every movement of the wrist into a change of atmosphere.

The chronograph center seconds measures elapsed time with clarity and precision, supported by a 30-minute counter and a 12-hour counter. At 3 o’clock, the moon phase introduces a poetic counterpoint, connecting mechanical time to celestial rhythm. A central analog date traced at the outer edge of the dial, while the small seconds at 9 o’clock adds visual equilibrium.

Together, these elements form a composition that feels layered, complex, yet entirely coherent. The white hands glide across the dial with confident contrast, linking heritage to a surface that feels unmistakably modern. Tradition is not replaced here, it is illuminated.

The 41 mm polished stainless-steel case carries the unmistakable Chronoswiss DNA: the iconic onion crown and screwed lugs that have defined the brand for decades. These details anchor the watch in its lineage while allowing the dial to take center stage.

Paired with a contemporary grey nubuck strap, the Aurora gains a fresh, understated elegance. The matte softness of the leather complements the dial’s shifting tones, creating a silhouette that feels refined and bold.

Inside beats the automatic Caliber C.755 with a power reserve of 46 hours. Visible through the sapphire case back, the movement reveals meticulous finishing that reflects Chronoswiss’ commitment to mechanical authenticity. Precision here is not an abstract promise. It is visible, tangible, and alive.

The Lunar Chronograph Aurora is not a reinvention for the sake of novelty. It is a careful evolution of a model that has shaped Chronoswiss for over two decades. Classic complications meet contemporary materials, expressive surfaces meet disciplined mechanics.

For collectors who value heritage but seek distinction, the Aurora offers both. A timeless chronograph, now seen in a different light.
