Case, Crown and Crystal — 40mm 18k White Gold Build
The Rolex Day-Date 228239 super clone carries a 40mm white-gold-tone case measuring 12mm in thickness, built on a 904L-grade stainless steel core finished with high-grade white-gold PVD for long-term color stability. The Day-Date 40 case profile widens the lugs and broadens the bezel compared with the prior 218239 generation, and this super clone reproduces that geometry at CNC tolerance.
Case Geometry and Finishing
The case finishing follows the Day-Date's vertical brushing on the lug tops, mirror-polished lug flanks, and a chamfered transition to the President bracelet. The Twinlock screw-down crown sits flush against the case, signed with the Rolex crown logo. The Day-Date 228239 case shape mirrors the genuine reference within tight dimensional tolerance, holding the same lug-to-lug span on the wrist.
Fluted Bezel, Sapphire Crystal and Caseback
The fluted white-gold-tone bezel rotates with the case and carries the precise 60 grooves of the genuine reference. Anti-reflective sapphire crystal covers the dial and includes the Cyclops 2.5x date magnifier at 3 o'clock. The screw-down solid caseback seals the Day-Date 228239 super clone to 100 meters of water resistance, suited to daily wear and incidental submersion.
