Casio has announced two new models in its Oceanus Manta line, the OCW-S7000CN-1AJF and OCW-SG1000CN-1AJR. Both are inspired by the calm and quiet of a moonlit night and feature hand-cut sapphire glass bezels made using traditional Edo Kiriko craftsmanship. The watches use black DLC-coated titanium cases and bands, combining durability with a premium finish.
OCW-S7000CN-1AJF
The OCW-S7000CN-1AJF features a sapphire glass bezel with precise, hand-cut lines crafted by Edo Kiriko artisan Toru Horiguchi. The pattern, known as “Thousand Lines,” captures reflections similar to the light of the moon on a calm sea. Each cut is made by hand on hard sapphire glass, which requires long hours of grinding and finishing.
The design theme “Calm Night” is expressed through an all-black titanium body and a bezel that reflects a subtle blue depending on the viewing angle. The dial has a textured matte surface inspired by the unevenness of the moon’s surface, giving it a soft, detailed look.
The watch measures 47.5 × 42.8 × 9.8 mm and weighs 81 g. It includes Bluetooth for smartphone link, MULTIBAND6 radio time correction, and Casio’s Tough Solar power system. Other functions include world time for 27 cities, a 1-second stopwatch, full automatic calendar, and a power-saving mode. It is 10 ATM water-resistant and fitted with a double-sided anti-reflective sapphire crystal. The indexes and hands feature Neobrite for low-light visibility.
The titanium band has arrow-shaped links with mirror-polished lines and a slide-adjustment clasp.
OCW-SG1000CN-1AJR
The OCW-SG1000CN-1AJR is a higher-end limited edition with only 600 units worldwide. It uses a sapphire bezel featuring the “Senjiku” pattern, also created by Toru Horiguchi. The bezel has 24 polished facets and a black-silver gradient achieved through vapor deposition, reflecting blue tones under light.
The dial uses a metal base embossed with textures resembling the moon’s surface, finished with layered plating and paint for depth. The emblem on the case back features a moon motif created through laser processing and DLC coating.
This model introduces Gallium Tough Solar, a solar system derived from satellite technology that improves power generation. It uses a crescent-shaped solar cell under the date window to collect light efficiently.
The watch measures 47.5 × 43 × 11.7 mm and weighs 99 g. It includes Bluetooth, MULTIBAND6, Tough Solar, and world time for 27 cities. Other features include automatic calendar, stopwatch, power-saving mode, and Neobrite hands. It is water-resistant up to 10 ATM.
The OCW-SG1000CN is made of black DLC-coated titanium with a dual-curved sapphire crystal and slide-adjustment clasp. It comes in a special box with a unique serial number.
