Ceramic Bezel Characteristics

The Rolex Watch Deepsea 136660 features a Ceracom ceramic bezel showcasing meticulous craftsmanship. The process begins with mixing nano zirconia powder with a specific amount of colorant and molding agent. After drying and curing, the dispersed particles are injected into a mold cavity through an injection molding machine to form the ceramic bezel blank. This is only a small part of the process. The green blank is then sintered at high temperatures for 96 hours at 1600°C to form the final product. After precise machining and surface polishing, the pure, bright green bezel emerges. The color is adjusted hundreds of times to present a hall-level golden green ceramic bezel, indistinguishable to the naked eye, even for professionals.

Bezel Details

The bezel markers of the Rolex Watch Deepsea 136660 are based on 3D scans of the original, with each numeral having larger gaps at the top and smaller gaps at the bottom, unlike the evenly spaced gaps found in market versions. The markers are laser-engraved and polished, with micro-chamfering at the edges, identical to the original.

Coloring Technique

The ceramic bezel’s numbers, markers, and lettering are colored using Physical Vapor Deposition (PVD). This process involves coating the ceramic with a one-micron thick layer of metal, which is then polished off, leaving the metal only in the recessed areas. This technique results in a brilliant sheen on the bezel, with the precious metal markings remaining clear and legible. The use of 18k platinum ensures the durability of the markings, preventing discoloration when exposed to water or oil.

Night Pearl and Sapphire Crystal

The bezel of the Rolex Watch Deepsea 136660 features a honey-colored luminous pearl with a double-sided spherical sapphire glass bead. The inner metal edge appears milky white when magnified, matching the color of the luminous markers. The bezel is attached to the base using an interlocking method, not double-sided tape, ensuring a secure fit. The bezel and base tolerance must be within 3 microns to prevent cracking during assembly.

Dial Details

The dial markers are smooth and rounded, with no imperfections. The printing on the dial is free of burrs, with a consistent and glossy finish. The markers are filled with Swiss Super-LumiNova BGW9, a luminous powder that appears as sandstone glass. The luminous intensity of the markers, hands, and pearl is consistent, with the luminous powder slightly recessed compared to the marker edges.

Hand Details

The hands feature chamfered edges, with the central hub of the second hand raised above the plane of the hand. Each hand is hand-polished and coated with genuine white gold, resulting in a bright and luxurious finish. The hands use Swiss BGW9 ice blue lume for superior visibility in the dark. The minute and hour hands are finely polished, with no visible burrs and a sharp, rounded tip.

Case and Crown

The case of the Rolex Watch Deepsea 136660 is made from imported 904L stainless steel, which contains 1.5 times more chromium, nickel, and molybdenum than 316L steel, making it more resistant to corrosion and oxidation. The case features high-strength brushing in many areas, and the shape is based on the original mold, with perfect replication of the original’s feel and aesthetic. The crown is screw-down with a triple-lock waterproof system, and the classic crown logo is engraved on the top, matching the original in size and position.

Caseback and Inner Bezel

The inner bezel features a laser-etched logo, with each watch having a unique serial number. The caseback has clear, three-dimensional teeth and a polished edge, identical to the original. The engraving on the case matches the original in font and finish.

Bracelet Details

The bracelet’s center links are brushed, while the sides are polished, providing a smooth feel. The three-link Oyster bracelet features a polished finish, with the inner details meticulously handled. The clasp includes the “dragon and phoenix” logo, engraved with the same technique as the original. The outer shell of the clasp is machine-pressed from a single piece of 904L steel.
