Rado is known for their ceramic watches for a long time already, but nowadays many watch brands have watches with ceramic casings in their program. The Omega Speedmaster Replica Blue Side of the Moon I’m wearing this week is not really an exception there. But why would a watch manufacturer choose ceramic as material for a watch casing?
The main reason would be the enhanced scratch resistance compared to stainless steel. And even more to precious materials like gold an platinum.Now all ceramics are harder than steel and/or gold. However, Omega Speedmaster Replica Watches they’re much easier to break or shatter as well.In fact, Zirconium Dioxide has the highest mechanical strength and fracture toughness of all major fine ceramics. These characteristics result in an extremely high resistance against wear.
Besides this strength, ZrO2 for a ceramic has a relatively high thermal expansion. As not all components of a wristwatch can be made of ceramics, metals have to be used in the construction as well. Think of the movement, winding shaft, etc. The thermal expansion of ZrO2 is almost equal to that of steel, and therefore often the material of choice for joining these materials.
Raw Zirconium Oxide is a white crystalline oxide made by heating to high temperatures in air or oxygen of Zirconium. The principal commercial source of Zirconium is the mineral Zircon. Two-thirds of Zircon mining occurs in Australia and South Africa. The worldwide annual total Zirconium production is approximately 1.5 million tonnes, which obviously isn’t all used for producing watch casings.
Best Omega Replica Watches Review full official model indication of the Omega Speedmaster Blue Side of the Moon I’m wearing is ‘Omega Speedmaster Moonwatch Co-Axial Chronometer Moonphase Chronograph 44.25 mm’. No less. This immediately informs about the diameter of the watch, which is rather impressive as well. In my opinion, however, it’s OK-ish for a chronograph of this importance.
