Reference: OCW-S7000CN-1A (Made in Japan - Yamagata Premium Production)

This watch is the definition of Japanese elegance. Belonging to the premium Manta S7000 line (the finest and most elegant), this special edition is a collaboration with the master craftsmen of Naito Indigo Dyeing.

The design captures the concept of “Kuro-zome”: an indigo blue so deep it borders on black, evoking the natural oxidation of traditional dye.

• The Sapphire Bezel: It is not metal, but a ring of vapor-deposited sapphire crystal. It features a mesmerizing gradient from blue-green to dark purple, mimicking the changing hues of natural dye.
• The Textured Dial: The dial is not smooth; it has a pressed texture that replicates hand-dyed fabric, with a gradient from black to dark blue.
• Black DLC Body: The entire titanium case and bracelet have a deep black DLC (Diamond-Like Carbon) coating, completing the “Stealth Luxury” aesthetic.

This is a JDM (Japan Domestic Market) model, difficult to find outside of Japan and manufactured on Casio's famous premium production line in Yamagata.

⚠️ STYLE NOTE (The “Look & Feel”)

• The Color: In studio photos it looks very blue, but in real life it is much more subtle and elegant. It is a dark watch, where the purple and blue tones of the bezel appear to “dance” when light hits the sapphire. It is not garish, it is mysterious.
• Comfort: At only 9.5mm thick and 83 grams, it is probably the most comfortable chronograph available. It slips under any dress shirt without snagging.
