Rolex Explorer II 216570 Super Clone: 42mm Oystersteel GMT with Caliber 3187 and Orange 24-Hour Hand

Case, Crown and Crystal - 42mm Oystersteel Build with Fixed 24-Hour Bezel

The Explorer II 216570 super clone features a 42mm Oystersteel case measuring 12.5mm thick, built on a 904L stainless steel core that matches the genuine reference for corrosion resistance and wrist weight. The 50mm lug-to-lug and 21mm lug width follow the 2011 case redesign that grew the Explorer II from the previous 40mm 16570 to the modern 42mm profile.

Case Geometry and Finishing

The case finishing follows the Explorer II's tool-watch grammar with a brushed top surface and high-polish chamfers along the flanks. Brushed satin runs across the top of the lugs and the case profile. Polished facets frame the case sides for legible light play under cockpit lighting and outdoor sun. The crown guards sit flush against the screw-down Twinlock crown at 3 o'clock for snag-free wear under explorer kit and travel layers.

Sapphire Crystal, Caseback and Fixed Bezel

Anti-reflective sapphire crystal with a Cyclops lens over the date covers the dial on the Explorer II 216570 super clone. The fixed Oystersteel bezel carries deeply engraved 24-hour Arabic numerals that the orange 24-hour hand reads against for second time-zone tracking. A solid screw-down Oyster caseback seals the movement against pressure, and the case holds 100 meters of water resistance for swimming, showering, and light water use.

 White "Polar" or Black Dial with Chromalight Hour Markers

The Explorer II 216570 super clone offers a choice of the signature white "Polar" dial or the classic black dial, both finished with Chromalight blue-glow luminous markers. The white "Polar" configuration uses black-finished hour markers and hands, with the orange 24-hour hand as the only color accent against the white background. The black dial configuration uses white-gold-tone hands with luminous fill, giving the handset a floating appearance against the matte black surface.

Rolex Coronet, Explorer II Script and Orange 24-Hour Hand

The applied Rolex coronet sits at 12 o'clock above the "EXPLORER II" script, with the orange "GMT" text and depth rating printed below 6 o'clock on the dial. The independent orange 24-hour hand sweeps once every 24 hours and reads against the engraved bezel for second time-zone tracking. The Mercedes-style hour and minute hands carry Chromalight, the same paramagnetic luminous material the genuine reference uses for blue-glow lume return.

Date Window, Cyclops and Pilot-Watch Legibility

The Explorer II 216570 super clone places the date aperture at 3 o'clock with a 2.5x Cyclops magnification lens on the sapphire crystal for fast date reading. The instantaneous date change at midnight follows the genuine Caliber 3187 layout. Pilot-watch and cave-explorer legibility holds across daylight, dusk, and full-darkness conditions for travel, expedition, and desk-side use.

 Swiss-Grade Clone of the Rolex Caliber 3187

The Explorer II 216570 super clone runs on a Swiss-grade automatic movement that matches the genuine Caliber 3187 in frequency, autonomy, and independent GMT-hand function. The movement operates at 28,800 vibrations per hour, holds 48 hours of power reserve, and uses a bidirectional Perpetual rotor for automatic winding. The genuine Caliber 3187 features Rolex's blue Parachrom hairspring and Paraflex shock absorbers, and the clone caliber follows the same architectural layout under the solid Oyster caseback.

Accuracy and Independent GMT Function

Daily deviation holds within -5 to +10 seconds per day on the Explorer II 216570 super clone after factory regulation. The independent 24-hour hand on the genuine 3187 sets in 1-hour jumps via the crown, separate from the main 12-hour hand, and the clone caliber follows the same setting logic for true second time-zone use. Travelers use the local time on the main hands and home time on the orange 24-hour hand reading against the engraved bezel.

Oyster Bracelet with Oysterlock Folding Safety Clasp

The Explorer II 216570 super clone features the 3-link Oyster bracelet with solid center links and brushed satin outer links, matching the genuine reference's tool-watch construction. The bracelet tapers from 21mm at the case to 18mm at the clasp. The Oysterlock folding safety clasp closes with the same double-push security mechanism the genuine reference uses, holding the bracelet flat against the wrist under daily strain.

Wrist Feel, Weight and Comfort

The Explorer II 216570 super clone weighs 155 grams approximately on the full Oyster bracelet, matching the wrist feel of the genuine Oystersteel reference within a 5-gram margin. The 42mm case sits flush on 6.5-inch to 8.5-inch wrists thanks to the 50mm lug-to-lug measurement and the slim 12.5mm thickness. The brushed bracelet finish hides daily-wear marks better than a polished bracelet, and the Oysterlock clasp prevents accidental opening during active wear.
