As winter approaches and the first snowflakes fall, it is as if the world pauses for a second. That is exactly the feeling Swatch has captured in its latest release: the Mission to Earthphase – Moonshine Gold “Cold Moon” (reference SO33W701L). It combines everything that has made the Bioceramic MoonSwatch collection popular — the clean white look, the gold accents, the moonphase, the earthphase, and Snoopy — but with a wintry twist that makes the model entirely unique.
A watch where no two are alike
The most fascinating thing about this new version is the lasered snowflake on the moonphase indicator. Each example gets its own motif, which means no watch is ever identical to another — just like real snowflakes. It is a detail that feels both playful and technically impressive, perfect for collectors who love that little something extra. The treatment is applied to one of the two full moons on the moonphase disc, both coated in OMEGA’s Moonshine™ Gold.
Design that captures the winter feeling
The white bioceramic case and bezel bring snow-covered landscapes straight to mind. Together with the subtle gold details on the moonphase and cool blue accents on the dial and bezel, the result is an expression that feels both fresh and luxurious. The watch keeps the layout that has made the Earthphase models so appreciated: the earthphase indicator with Earth against a starry sky (Swatch’s twist that shows how Earth appears from the Moon, following the 29.5-day cycle in reverse), the moonphase with two full moons in OMEGA Moonshine Gold, the asymmetric Speedmaster case, and the tachymeter with the classic “dot over ninety.” And as always in the MoonSwatch world, there is a discreet but charming link to Snoopy — here Snoopy and Woodstock reworked at nine o’clock to suit the winter theme.
The details that make the whole
Swatch continues to use its own bioceramic, which gives the watch a light and modern feel on the wrist. The glass is domed and made of biosourced material with an engraved “S” in the centre. The hour markers and hands glow strongly in the dark thanks to Grade A Super-LumiNova, and both the moonphase and earthphase offer secret UV details that only appear under blue light — including a hidden phrase next to Snoopy nodding to the pioneering spirit of the Moonwatch. The battery hatch is adorned with an earth-inspired design, and the model comes on a white VELCRO® rubber strap (with a white bioceramic loop) that reinforces the overall feel. In brief, the specifications: a 42 mm white bioceramic case, 13.75 mm thick, 47.3 mm lug-to-lug, a quartz movement with chronograph (seconds), moonphase, and earthphase, water resistance to 3 bar, a domed biosourced crystal with engraved S, and a white opaline dial with a Moonshine Gold moonphase.
Availability — but only when it snows
The sale started on 4 December 2025 — the same day as the Cold Full Moon. The model was sold globally until 20 March 2026, but with an unusual rule: after the premiere day it was released only when it was snowing in Switzerland. That means even countries without winter weather followed the weather reports with excitement, hoping for the next snowfall. The retail price is CHF 350 (around €385 / USD 450), consistent with prior Moonshine Gold editions.
A winter dream for anyone who loves the white MoonSwatch look
The clean all-white design has long been a favourite among MoonSwatch fans, and here it is joined by everything that makes the model special: gold, moonphase, earthphase, and Snoopy — topped with the unique snowflake that makes each example personal. For the watch that started this whole collaboration, see our look at the Omega x Swatch MoonSwatch.
