The Swatch x Omega Bioceramic MoonSwatch Mission to Earthphase – Moonshine Gold (SO33W701L), known as the “Cold Moon” edition, is a serene yet enchanting timepiece inspired by December’s Cold Moon. Featuring a crisp white bioceramic case, icy blue accents, Moonshine™ Gold details, and a winter-themed Snoopy & Woodstock design, this special edition blends frosty seasonal charm with classic Speedmaster DNA. Released in celebration of the December Cold Full Moon, it captures the magic of winter nights, the beauty of lunar cycles, and the excitement of collecting unique limited-release MoonSwatches.
Key Features
✅ Official Swatch × Omega Collaboration — Part of the Bioceramic MoonSwatch collection, combining Swatch’s creative, playful design and Omega’s Moonwatch heritage.
✅ White Bioceramic Case & Strap — The Cold Moon features a white Bioceramic case, crown, and pushers, paired with a matching white rubber strap with VELCRO® closure and a white Bioceramic loop — giving it a crisp, wintry aesthetic.
✅ Earthphase Complication — At 10 o’clock, the watch displays an “Earthphase” indicator showing Earth as seen from the Moon, with oceans that glow blue under UV light.
✅ Moonphase with Moonshine™ Gold Moons — At 2 o’clock sits the moonphase sub-dial with two full moons, both coated in Omega’s Moonshine Gold. One moon bears a distinctive Snoopy-style design, while the other features a unique snowflake motif — each snowflake being individually laser-engraved so no two watches are identical.
✅ Snoopy & Woodstock Illustration with Winter Twist — Beneath the Earthphase indicator there’s an illustration of Snoopy and Woodstock (in space-gear), now given a snowy/winter re-imagining for the Cold Moon edition; a hidden phrase becomes visible under UV light.
✅ Quartz Chronograph Movement (Chronograph Seconds Only) — The watch uses a quartz movement, powering timekeeping plus the Earthphase and moonphase complications.
✅ Super-LumiNova® Accents — Hour markers, hour & minute hands, and the tip of the chronograph seconds hand are coated with Grade A Super-LumiNova® (green emission) for visibility in the dark.
✅ Distinctive Design Details — Features include a white opaline dial, recessed sub-dials, a fine circular-patterned outer dial ring, a box-shaped bio-sourced glass crystal engraved with the Swatch “S”, and an Earth-inspired battery cover — all hallmarks of the MoonSwatch lineage.
✅ Limited & Seasonal Release — The Cold Moon edition was released on 4 December 2025 (the Cold Moon) and is available until 20 March 2026 — but after the initial release, it will only be available for purchase on days when it is snowing in Switzerland.

Why Choose the “Cold Moon” (SO33W701L)?
The Cold Moon edition stands out as a seasonal, whimsical, and collectible take on the Earthphase MoonSwatch line. Its all-white Bioceramic treatment — combined with deep-blue sub-dials and Moonshine Gold moons — creates a “winter snow / arctic night” aesthetic that’s distinct among MoonSwatches. The unique, laser-engraved snowflake motif on the moonphase dial gives each piece its own identity, reinforcing the idea of a “no two the same” collectible. Meanwhile, the presence of beloved characters (Snoopy & Woodstock), UV-reactive details, and the rare Earthphase complication make it a fun yet tasteful nod to both space lore and pop culture. If you value individuality, storytelling, and a design that's seasonal yet wearable, the Cold Moon is a strong candidate.
