Fischer XRF Au750 (75.0%) & Mettler-Toledo Gravimetric Verification

The Rolex Day-Date 36 Gibeon Meteorite Dial 18K Everose Gold Reference 118135 is a direct Swiss foundry specimen engineered in 18K Rose Gold Au750 (36.0 mm x 12.0 mm) with a certified Mettler-Toledo mass of 118.9g, Fischer XRF Au750 metallurgical verification, and Rolex Manufacture Cal. 3155 running at 28,800 vph (+0.4 s/d, 302 deg) with a 72-hour power reserve and 100m / 330 ft - Twinlock Screw-Down rating.

Catalogued in our direct Swiss foundry Rolex assay archive under Specimen Code LAB-XRF-118135-W600, this Rolex Day-Date 36 Gibeon Meteorite Dial 18K Everose Gold Reference 118135 is smelted and CNC-machined in 18K Rose Gold Au750 (36.0 mm x 12.0 mm). Prior to archival release, the completed assembly is weighed on a calibrated Mettler-Toledo balance at 118.9g and scanned via non-destructive Fischer XRF spectroscopy.

How Is the Authentic Gibeon Meteorite Widmanstatten Dial Crafted on Rolex Ref. 118135?

The Rolex Day-Date President Reference 118135 features a genuine extraterrestrial Gibeon iron-nickel meteorite dial displaying an acid-etched Widmanstatten crystalline lattice pattern inside a 36.0 mm x 12.0 mm 18K Rose Gold Au750 case weighing 118.9g, because octahedral nickel-iron crystals cool over millions of years in space to form unique non-repeating metallic striations.

REFERENCE-SPECIFIC COLLECTOR Q&A
What laboratory instruments certify Reference 118135 (Rolex)?

Every 18K Factory specimen is verified on three calibrated instruments on 4K video: a Mettler-Toledo analytical balance (118.9g), a Fischer XRF spectrometer (18K Rose Gold Au750), and a Witschi Chronoscope (+0.4 s/d, 302 deg).

Does the 118.9g reading match the authentic original Rolex 118135 weight?

Yes. Our CNC foundry machines the 18K Everose Gold case and bracelet to replicate the exact 118.9g reference mass of the authentic manufacture timepiece.

What are the movement specifications for Reference 118135?

Reference 118135 is powered by the Rolex Manufacture Cal. 3155 operating at 28,800 vph (4 Hz) with a 72-hour power reserve, regulated across six positions to +0.4 s/d, 302 deg.

Is the dial on Rolex Ref. 118135 crafted from real Gibeon iron-nickel meteorite?

Yes. Each Rolex Day-Date President Ref. 118135 dial is sliced from genuine Gibeon metallic meteorite and acid-etched to reveal its natural Widmanstatten crystalline lattice inside our 118.9g 18K Rose Gold Au750 case.
