A sight to behold is this Sarpaneva Korona K0 Northern Lights special edition in stainless steel featuring a special dial created in collaboration with James Thompson of Black Badger. Underneath the recognizable Sarpaneva skeletonized blue grille lies a plate coated with Black Badger's insanely bright proprietary luminescence inspired by the Northern Lights over Finland. At 6 o’clock, an aperture reveals one of two solid gold “Moonfaces”... one Moonface crafted in 18k white gold, the other in rose gold tracking the 29.5-day lunar cycle.
The reverse side reveals Sarpaneva's grille-style rotor mounted with 4 large and 2 small solid gold weights and yet another white gold Moonface. Underneath the rotor is the modified Soprod A10 movement which operates at 4 Hz and carries a Power Reserve of 42 hours.
The 46mm scalloped case is one of my favorites across any maker and wears smaller than its size suggests. The thickness (including crystal) measures 11.8mm and is 50 millimeters lug-to-lug. No Box & Papers.
This watch received a Complete Overhaul at the Sarpaneva atelier February 2025.
