Sarpaneva Moomin 80: A Masterclass in Multi-Color Super-LumiNova Artistry
Sarpaneva Pushes the Boundaries of Lume with Ten Super-LumiNova Colors
Finnish watchmaker Stepan Sarpaneva has unveiled the Sarpaneva Moomin 80, a pair of special edition timepieces celebrating the 80th anniversary of Tove Jansson's beloved Moomin characters. What makes these watches truly remarkable is their unprecedented use of ten different Super-LumiNova colors on a single dial — a feat of lume artistry that transforms the watch face into a luminous painting after dark.
How Ten Lume Colors Create a Living Dial
The three-part stainless steel dial recreates an illustration from Jansson's 1946 book Comet in Moominland, bringing the scene to life with a vivid night sky and a comet streaking overhead. Each element of the artwork is hand-finished and hand-painted with Swiss Super-LumiNova, using ten distinct color formulations to achieve the full spectrum of the original illustration.
When charged under light and viewed in darkness, the dial transforms entirely. The Moomin characters, the night sky, and the comet each glow in their designated colors, creating what Sarpaneva describes as a "fascinating tale in Super-LumiNova." The current hour is revealed through an aperture at 12 o'clock, while a two-tone Super-LumiNova-treated hand indicates the minutes.

Two Editions: Color and Monochrome
The Moomin 80 is available in two variants. The colored edition features the full palette of ten Super-LumiNova hues, while the monochromatic edition echoes the original black-and-white book print — both glowing brilliantly in the dark. The case is crafted from high-grade Outokumpu steel, measuring 42mm in diameter and 11.4mm thick, with 100m water resistance.
Technical Specifications
Powered by a modified Soprod A10 calibre with 42-hour power reserve, the Moomin 80 features a skeletonized winding rotor with Sarpaneva's signature Moonface design in white gold with Super-LumiNova accents. The front sapphire crystal has multiple layers of AR coating, and the caseback is transparent.
Why Super-LumiNova Matters in Modern Watchmaking
Super-LumiNova, produced by Swiss company RC Tritec, is the gold standard for photoluminescent watch markings. Unlike older tritium-based lume, it is non-radioactive, reusable indefinitely, and available in over 40 colors. The BGW9 variant (blue-green glow) and C3 variant (green glow) remain the most common, but Sarpaneva's use of ten distinct formulations demonstrates how far the technology has come.
Frequently Asked Questions
Q: How long does Super-LumiNova glow after charging?
A: Super-LumiNova reaches full brightness almost instantly and remains visible for 6-10 hours depending on the grade and thickness of application. After 30 minutes in darkness, it typically retains about 50% of its initial brightness.
Q: What is the difference between BGW9 and C3 Super-LumiNova?
A: BGW9 emits a blue-green glow and appears white in daylight, making it ideal for dress watches. C3 produces a bright green glow and appears cream/green in daylight, offering maximum brightness for dive and tool watches.
Q: Is the Sarpaneva Moomin 80 limited?
A: Yes, only 60 pieces will be produced — 30 with colored dials and 30 in monochrome. Each is priced at EUR 13,500 excluding taxes.
