Finnish watchmaker Stepan Sarpaneva has said his ambition is to “seek out unique designs that are both elegant and completely unorthodox.”
This Korona Northern Lights is a perfect example of his philosophy. Its incredibly luminous dials in blue, green and violet showcase Sarpaneva’s signature precision moon face in gold.

Driven by an automatic Soprod A10 movement, the Korona Northern Lights is exquisitely finished and offers a rare example of the successful fusion of scrupulous watchmaking craftsmanship with unbridled creative freedom.
