Koi-Bra - Custom 39mm Seiko MOD - Daytona-Style VK63 Chronograph
KOI-BRA
WHERE UNEXPECTED COLORS SWIM TOGETHER.
Koi-Bra makes an impression before you even get to the details. Its smoky, pearl-like dial brings together swirling shades of silver, charcoal, and black, while gold-tone hands add a flash of warmth against the shifting pattern.
The coffee-bronze case takes the design in a different direction from the usual stainless-steel chronograph. A contrasting black-and-white bezel sharpens the look, and the black textured strap completes the combination without taking attention away from the dial.
At 39mm, this Daytona-style custom MOD brings together unusual colors and contrasting finishes in a design that feels deliberate from every angle. The gold hands tie into the warm case, while the cool, marbled dial keeps the whole watch from feeling predictable.
Inside, the genuine TMI VK63 Seiko quartz chronograph movement provides dependable timekeeping and chronograph functionality. Sapphire crystal protects the dial, and the watch carries a 5 ATM water-resistance rating.
Koi-Bra is proof that the right combination doesn't have to be the obvious one.
