Replica KB Factory Rolex Yacht-Master “Rainbow Bezel”

Design & Gem Setting

KB Factory achieves near-perfect color gradation on its rainbow bezel, using hand-set baguette-cut sapphires that transition smoothly through pink, violet, and blue tones. Each stone is aligned with laser-guided positioning to ensure perfect symmetry and depth. The lugs are micro-paved with high-clarity cubic zirconia, creating a seamless sparkle under any light — a finishing touch that closely matches Rolex’s genuine gem-setting standards.

The black lacquered dial enhances the contrast of the gemstones, while the polished white-gold-tone hands and hour markers ensure excellent legibility. Every marker is evenly filled with Swiss-grade Super-Luminova, glowing evenly in dim environments.

Case & Build Quality

Crafted from 316L stainless steel, the KB version maintains a flawless polish and precise lug curvature. The 904L option upgrade is also available for collectors who demand authentic weight and corrosion resistance comparable to the real Yacht-Master. The case thickness (12.3 mm) and crown guard shape are identical to the genuine reference, maintaining accurate proportions and wrist comfort.

The sapphire crystal includes an ultra-clear cyclops lens with correct magnification (2.5×), and KB’s latest anti-reflective coating reduces glare significantly under sunlight.

Movement

Powered by the Seagull 2824 automatic movement, this KB edition offers:

• Stable timekeeping accuracy (±10 s/day)

• Smooth second-hand sweep (28,800 vph)

• Instant date jump mechanism

• 38–40 hour power reserve

Collectors can optionally upgrade to the Dandong 3235 clone movement, achieving a longer 70-hour reserve and enhanced stability — the same specification found in Clean Factory’s higher-end releases.

Strap & Comfort

The black FKM rubber strap matches Rolex’s Oysterflex in both flexibility and matte finish. It conforms naturally to the wrist and resists sweat, UV, and water exposure. The polished steel clasp carries deep Rolex engraving, and the deployment action feels solid and secure, reflecting KB’s improved engineering precision in 2025 models.
