Rolex GMT-Master II 126713 Clean Factory Collect– Black Dial 3285 Movement In-Depth Review

Introduction to the C Factory GMT-Master II 126713

The Rolex GMT-Master II reference 126713 is a modern two-tone interpretation of the iconic pilot's watch, blending stainless steel with 18K yellow gold. The Clean Factory (often referred to as C Factory) has produced a super clone version that aims to replicate every detail, from the black lacquered dial to the Cerachrom bezel insert and the in-house 3285 movement. For buyers seeking an affordable alternative that closely mirrors the genuine piece, this Collectoffers a compelling balance of aesthetics and function.

Clean Factory – Crafting a High-Grade Collect

Clean Factory has built a reputation among Collectenthusiasts for its attention to case finishing, bezel engraving, and movement replication. Their GMT-Master II 126713 is no exception. The case is 40mm in diameter, machined from 316L stainless steel, and features sharp edges with a mix of brushed and polished surfaces that match the genuine. The crown guards are correctly shaped, and the winding crown sits flush with the case. The sapphire crystal is slightly domed with a colorless anti-reflective coating, just like the original.

Dial and Hands – Black Lacquer with 18K Gold Accents

The black dial is glossy and deep, with applied hour markers crafted in 18K yellow gold (simulated via gold-plating on the Collect). The Chromalight lume on the hands and hour markers emits a consistent blue glow after charging. The hands are correctly proportioned, with the GMT hand finished in gold to match the bezel. The Cyclops lens over the date window is magnified 2.5x and aligned perfectly, a common flaw in lower-tier Collectthat C Factory gets right.

Bezel and Bracelet – Two-Tone Excellence

The bidirectional 24-hour bezel is the centerpiece of the GMT-Master II. On the 126713, the bezel is solid 18K yellow gold (on the Collectit is gold-plated stainless steel with a precise color match). The gray and black Cerachrom ceramic insert has deeply engraved numerals and graduations filled with platinum-colored paint. The bezel action is crisp, with 120 clicks and no backplay. The bracelet uses the 'Intergold' five-piece link design: brushed stainless steel outer links and polished gold center links. The Easylink extension system is functional, allowing a 5mm adjustment.

The 3285 Caliber – Performance of the Clone Movement

The Clean Factory Collecthouses a clone of Rolex’s calibre 3285, a self-winding movement with a 70-hour power reserve. The rotor is gold-plated with correct Geneva stripes, and the balance bridge is engraved. The movement hacks and hand-winds smoothly. Accuracy out of the box is typically within +/-5 seconds per day, which rivals many genuine Swiss movements. While the finishing is not as fine as the genuine, it is transparent through the exhibition caseback and looks convincing at a glance.

Buying Tips – How to Choose a Top-Tier Collect

When evaluating a Clean Factory GMT-Master II 126713 Collectconsider these critical points:

• Bezel font thickness: Compare to genuine photos. C Factory uses a slightly bolder font than some competitors but is close to gen.
• Case finish: The lugs should be sharp, not rounded. The chamfers on the lugs should be polished and defined.
• Dial lume: Under UV light, the lume should be applied evenly without blotches. The color should be blue, not green.
• Weight: The Collectweighs about 155 grams (genuine is around 170g), so it feels substantial but slightly lighter due to gold plating vs. solid gold.
• Crystal height: The sapphire should protrude slightly above the bezel, with a subtle dome.

Fake vs. Real Checks – Spotting a Clean Factory Collect

Even the best Collecthas tells. For the 126713, inspect:

• Date wheel: Genuine has open 6 and 9, the Collectmay have slightly different font.
• Gold hue: The Collectgold can be a touch brighter; compare under sunlight.
• Rehaut engraving: The inner ring should have 'ROLEX' repeated, with the crown at 12 perfectly centered. On the Collectthe alignment is often slightly off.
• Movement decoration: Genuine 3285 has a fully gold-plated rotor and blued screws; the clone has faux blued screws but the gold plating is lighter.

Who It Suits – Styling and Lifestyle

The two-tone black and gold GMT-Master II is versatile. It works for business attire (suits with a crisp white shirt) and casual weekends (jeans and a polo). The black dial reduces glare, making it legible in bright conditions. It is an excellent choice for travelers, collectors who want the look of a gold Rolex without the investment, or anyone who appreciates the aesthetics of the 'Root Beer' bezel (gray/black) but prefers a darker dial.

Styling Notes

• Pair with warm-toned accessories (brown leather belt, gold ring) to complement the gold accents.
• Wear on the bracelet for a classic look, or swap to a black rubber strap for a sportier vibe.
• Avoid overly flashy clothing; let the watch be the statement piece.
