Casio's new limited-edition titanium Oceanus watches now available to buy

Casio's Oceanus Retro Tone Collection (check out our launch coverage here) amounts to 800 watches for the Japanese market and nothing beyond it. As of August 7, both references have moved from reservation to direct sale.

That total gets an uneven split. The Manta OCW-S400RL-8AJR is capped at 300 pieces at ¥165,000, roughly $1,040. The Classic Line OCW-T2600RL-3AJR runs to 500 at ¥115,500, about $730. Neither is scheduled for release abroad, which means that overseas buyers will have to look towards proxy services (and the markups attached to them).

The dial work is where most of the value resides. Casio has built the gradient in three layers over a molded base — silver vapor deposition, colored coating, then a printed gradation pattern — finished half-matte, so that color and light radiate outward from the center. The main constraint is that a solar watch needs light to reach the cell beneath, so transmittance had to be carefully tuned.

Both ship on full vegetable-tanned calfskin from Tochigi Leather, a Japanese tannery operating since 1937. This material was specifically chosen because it patinas visibly with wear rather than staying the same over the years.

The Manta features premium hardware: a sapphire bezel ring, laser-treated across its top surface to a half-matte finish (Casio compares this to frost), plus Bluetooth syncing to the Casio Watches app. The Classic Line skips the wireless link entirely. Both are equipped with Tough Solar, and radio time correction across six global transmitters and world time for 29 cities. The Classic Line case measures 48.2 × 42.8 × 10.7 mm in titanium, weighs 49 grams, and is rated to 10 bar.

For scale, Casio's Oceanus Manta S7000 Awa indigo edition was limited to 800 pieces and did end up reaching the US at $1,900 earlier this year. Retro Tone's two references are relatively more limited, and so far, they have no equivalent route out of Japan.
