A rare design from Seiko’s eccentric archives, this reversible double-dial watch from The Blackdiamond Collection is a playful yet elegant statement of duality. Powered by the minimalist V400 quartz movement, it strips watchmaking down to its essentials—then flips expectations entirely.
On one side, a classic Roman numeral dial in white evokes a refined, almost neoclassical charm. On the other, a sleek, matte black face with polished stick markers and a diamond-shaped hour hand adds a bold, contemporary edge. The rotating case lets you choose your mood, whether formal or avant-garde.
Crafted with a two-tone case—brushed steel paired with a gold-tone bezel—and paired with a black leather strap, this piece balances quirk and class. It’s a prime example of why The Blackdiamond Collection has become a cult favorite: each model in the series brings a unique twist to Seiko’s precision watchmaking.
Key features:
- Reversible case with dual dials – dress up or down with a flip
- Roman numeral dial vs. minimalist noir dial for dual styling
- From the collectible Blackdiamond Collection – known for its quirky and uncommon designs
