Casio Oceanus “Calm Night” Edition Brings Moonlit Craftsmanship to the Wrist

Casio’s Oceanus line has always stood at the intersection of precision and poetry, but the new “Calm Night” Limited Edition takes that balance to an entirely new level. Inspired by the soft glow of moonlight reflected on still water, these new timepieces are less about status and more about serenity — an ode to Japanese craftsmanship wrapped in modern solar technology.

Two models anchor this release: the OCW-S7000CN-1AJF and the OCW-SG1000CN-1AJR, both part of the Oceanus Manta family. Casio describes the series as a “fusion of beauty and technology,” but this time, it’s also a love letter to traditional artistry. Each bezel is hand-cut from sapphire glass using Edo Kiriko, a centuries-old glass-cutting craft from Tokyo. The work is done by master artisan Toru Horiguchi, whose precision cuts create patterns that shimmer like moonlight rippling across calm seas.

The OCW-S7000CN-1AJF captures this motif through its “Thousand Lines” pattern — a precise lattice of cuts that refract light in subtle blue hues, depending on the angle. The all-black DLC-coated titanium case and bracelet reflect the night sky’s depth, while the matte lunar-textured dial adds a tactile sense of quiet detail. Inside, it runs on Casio’s Tough Solar system with Bluetooth connectivity, MULTIBAND6 radio control, and world time for 27 cities. At 9.8mm thin and 81 grams, it’s remarkably lightweight yet undeniably premium.

Then comes the OCW-SG1000CN-1AJR — the true collector’s piece. Limited to just 600 units worldwide, this model takes the moonlit theme further with a “Senjiku” bezel pattern featuring 24 hand-polished facets and a black-to-silver gradient achieved through vapor deposition. The result is a play of shadow and reflection that feels alive on the wrist. Its case back bears a laser-engraved moon emblem, echoing the watch’s celestial muse.

Beyond aesthetics, this flagship model introduces Gallium Tough Solar, a next-gen solar tech inspired by satellite engineering. A crescent-shaped solar cell discreetly sits beneath the date window, ensuring optimal light absorption without disrupting the design. The craftsmanship extends to every touchpoint — from the dual-curved sapphire crystal to the slide-adjustment titanium clasp that adapts smoothly to the wrist.

Priced at ¥308,000 (US$2,023) for the OCW-S7000CN and ¥682,000 (US$4,480) for the limited OCW-SG1000CN, both models arrive in November 2025, each housed in an exclusive presentation box.

While Casio is best known for its rugged G-Shocks, the Oceanus line has quietly become its platform for elegance — where technology doesn’t overpower design but enhances it. “Calm Night” feels like a meditation on that philosophy, blending modern engineering with traditional artistry in a way only Japanese watchmakers can.

This isn’t just a watch drop — it’s a reminder that even in an age of smartwatches and hyper-connected wearables, there’s still something deeply human about timepieces that reflect the light of craftsmanship under the calm of the moon.
