A crystal is an ordered solid material in which the atoms or molecules are arranged in a pattern that repeats in all three dimensions. Sapphire is second to diamond only in terms of hardness due to its atomic structure. The atomic structure makes sapphire crystal resistant to changes in shape. However, this also means that it is difficult to machine the crystal into complex shapes. From a seed, crystals can be grown in a number of ways. Raw crystal shapes can be used in a variety of ways. The smaller round crystals (Rolex Cellini Replica Watches) are cut into discs and shaped to be round. They are then polished using machines that rotate the discs in a paste. If you have enough discs and cutting machines to polish, then you can make 60,000 flat round watch crystals per year.

The Kyropoulos technique is used to grow crystals in more complex shapes. This method allows for the growth of large sapphires with optical qualities that are first or second grade. This method is what is used to make the crystal in the Rolex Cellini Replica Watches RM 056. Crystals with curved surfaces for different watch brands and the crystal developed for the RM 053-01 are a step above. Crystal watch cases have been used by other watch brands, but they are usually round with flat surfaces and no complexity in the case to hold the watch movement. The machining and polishing crystals are relatively easy if the case must be flat. It was not easy but it was within the limits of what we knew about machining crystal in more complex shapes on a smaller scale.

Rolex Cellini Replica Watches's watch cases are unique in that they have a three-part design. The three pieces must fit together within 1/100 millimetres. Rolex Cellini Replica Watches's RM 056 case is fully functional and has a 30-metre water resistance rating. Even though the case is made of well-known materials, it is still one of the more complex shapes to produce. To ensure accuracy, specialised measuring equipment must be used.

Both the upper and lower part of the case is curved, and not monotonic. The curvature of the case is not constant: it can be shallow in one place and slightly steeper elsewhere. Such curved surfaces are possible with a CNC machine that is accurate and within tolerances. It's a different story with crystal.Omega Aqua Terra Replica Watches The biggest problem is that you can cut out the basic shapes of the crystal pieces for the case but the real problems are in the polishing and finishing. The polishing is not visible! The polishing is done in a pot filled with viscous sand and cannot be measured. The piece must be removed from the machine to take periodic measurements and polish it to the required standard. If the tolerance is not within 1/100ths of a millimetre (at every point of contact between case parts), then the part will be rejected.

The drilling of holes for screws, pushers and the crown can cause further problems. The drilling could cause the crystal to shatter or crack at any moment. All the hard work done so far can be lost. It's as if the whole process is waiting for something to go wrong! Rolex Cellini Replica Watches's case has a complex middle section with a number ridges that are used to screw the movement into the case. In a crystal case, all ridges and surfaces must be polished to a high standard. There is no hiding place!
