Mounting the hands to an automatic movement to make it preciously leveled is an acquired skill. Our watch masters do each assembly process to ensure the highest precision and integrity of the watch.

We follow the original design on the bezel, gasket, and back casing. The gasket and back casing are crucial to waterproofing the watch up to 300M. All our Clean Factory Rolex are fitted with Real Swiss Abyss Deep-Sea Water Sealants and unique Abyss double-core synthetic ”O” Rings. These are made from an Abyss patent combination of polymer neoprene and Fluorocarbon synthetic rubber, which is far more resistant to cracking, corrosion, and aging, which can be a problem with natural rubber. All our Clones are now pressure tested to 10 bars, so they are waterproof to 100 meters!

The back covering the watch’s case is one solid piece of stainless steel. This ensures that the watch is pressure-proof to handle deep-sea diving. Some of our Rolex watches come with a real green hologram sticker, which is glued perfectly on the back. As of 2012, real Rolex models no longer come with holograms, so we removed them from our models.

Our selected diver’s models now come with a working Helium Release Valve and the same extra-thick Sapphire crystal as the original, making them waterproof to 300 meters. Although slightly less flexible, it was developed to withstand high oxygen environments and other hostile chemicals and gases that will quickly deteriorate natural rubber gaskets.

The bezels are designed with smooth unidirectional or bidirectional clicks to achieve high accuracy. We use real, solid, high-tech ceramic material. They have 100% the same construction as genuine.

Each Ultra Durable In-House DanDong Clone Swiss caliber is fine-tuned at the final stage to ensure the time accuracy is within the Contrôle Officiel Suisse des Chronomètres standard of +6/-4 seconds per day using the most advanced digital Timegraphers. Also, two testing machines simulate extreme “G-Forces” on the movement to ensure flawless operation. A power drop machine simulates a three-meter drop onto a wooden floor – a long-standing Swiss standard is that a watch case and movement should withstand such a fall. The watch band is tested for strength and durability in our automatic Band Tester for 3 hours. A machine does torsion testing to test the strap’s strength and long-term durability.
