🌊 The Seigaiha Motif: Tradition with a Minimalist Twist

The main attraction of this -7JR edition is its silver dial, which pays homage to Japanese culture through subtle details of fine watchmaking:

• Silver Seigaiha Pattern: The dial features the traditional motif of waves and seas in overlapping concentric arcs. In Japanese culture, this pattern evokes the uninterrupted flow of the ocean, symbolizing the wish for lasting good fortune and peaceful days.
• Subtle, Shimmering Luster: Treated with an advanced combination of vapor deposition and printed finishes, the silver dial shifts in tone depending on the angle of the light. The result is a refined look that contrasts beautifully with the digital LCD display.
• A nod to local craftsmanship: The case back features the word “Casio” engraved in both English and katakana characters, a mark of authenticity reserved for the most special Made in Japan pieces.
• Special Gift Packaging: It comes in exclusive packaging designed specifically for this collection, making it a coveted item for collectors or an unforgettable gift.
