In a move that has watch enthusiasts and Casio aficionados buzzing, the Japanese electronics giant has unveiled a stunning new addition to its premium Oceanus line. The Casio Oceanus Manta OCW-S7000CN-1A has been released in Japan, marking a significant step in the brand's pursuit of high-end, technologically advanced timepieces. Launched in October 2025 under the evocative "Calm Night" design theme, this watch isn't just about telling time—it's about making a statement.
Unveiled alongside its sibling, the OCW-SG1000CN-1A, the Manta model immediately stands out with its sleek, almost stealthy aesthetic and impressive list of features. But what makes this watch so special, and is it worth its premium price tag? Let's dive into the details.
First Impressions: A Study in Midnight Elegance
The moment you lay eyes on the Oceanus Manta OCW-S7000CN-1A, the "Calm Night" theme becomes brilliantly clear. The watch case and bracelet are crafted entirely from black DLC-coated titanium, a material chosen for its exceptional strength, light weight, and resistance to scratches. This gives the watch a sophisticated, matte-black profile that is both modern and timeless.
Measuring 47.5mm by 42.8mm with an incredibly slim profile of just 9.8mm, the watch wears much smaller than its dimensions might suggest. This sleek, low-profile design ensures it slides comfortably under a shirt cuff, making it as suitable for a boardroom as it is for a weekend outing. The star of the show, however, might be the sapphire glass bezel. Casio has expertly cut angled lines into this incredibly hard material, creating a mesmerizing play of light that dances across the watch's surface with every subtle movement of the wrist.

The Dial: Depth and Legibility in the Dark
Peer through that sculpted sapphire bezel, and you'll find a textured black dial that evokes the deep, quiet stillness of a night sky. The dial houses three classic analog hands for timekeeping, complemented by three sub-dials that add functionality without cluttering the elegant face. A key feature for a watch of this caliber is the automatic hand position correction function, which ensures the hands are always perfectly aligned, maintaining precision and aesthetic integrity.
As reported in a detailed hands-on feature by MyNavi, the legibility and craftsmanship of the dial are exceptional, reinforcing its position as a true premium offering from Casio. You can read their in-depth initial impressions here.
Brawn and Brains: A Technological Powerhouse
Beneath its calm exterior lies a heart of pure technological innovation. The Casio Oceanus Manta OCW-S7000CN-1A is a "connected analog" watch in the truest sense. It leverages both radio-controlled timekeeping (via Japan's Multiband 6 system) and Bluetooth connectivity to ensure it is never more than a second off from the atomic clock standard.
By connecting to the dedicated Casio Watches smartphone app, users can access a suite of tools and settings. This includes easily switching between world time zones, setting alarms, and managing other functions that are more conveniently handled on a phone screen. The watch also features a precise 1/1-second stopwatch for timing events.
Practicality is a cornerstone of the Oceanus line. With 10 ATM water resistance, this watch is more than capable of handling swimming and snorkeling, while the Tough Solar charging system means any light source—sunlight or indoor lighting—is enough to keep the battery perpetually charged, eliminating the need for battery replacements.
Pricing, Availability, and the Big Question
The Casio Oceanus Manta OCW-S7000CN-1A carries a retail price of ¥308,000 (approximately $1,968) in Japan. Interestingly, while the watch is listed on Casio's Japanese online store, initial reports indicate it is currently only available for purchase at Casio's physical retail locations in the country.
This limited availability raises the most significant question for international fans: Will the OCW-S7000CN-1A be released outside of Japan? Casio America already sells Oceanus models, such as the reference OCW-S7000E-2A, which is currently available for $1,350. The existence of a similar model in the US lineup gives hope that the "Calm Night" Manta may eventually make its way to other markets, but Casio has yet to make an official announcement.
Final Thoughts
The release of the Casio Oceanus Manta OCW-S7000CN-1A is a clear signal that Casio is deeply committed to competing in the luxury watch segment. It masterfully combines a sophisticated, Japanese-design-focused aesthetic with the brand's unparalleled expertise in practical, cutting-edge technology. For those in Japan who can get their hands on one, it represents a unique opportunity to own a piece of modern horological art. For the rest of the world, we can only wait and hope that this "Calm Night" will soon dawn in our markets as well.
