Description
Omega Constellation 123.10.38.21.01.001 VS Factory Black Dial Replica Watch.To better appreciate the fine details of the watch, Omega uses scratch-resistant and anti-reflective sapphire glass. Before machining and finishing, sapphire glass is produced using the Werner method (also known as the flame fusion method). It involves using a hydrogen-oxygen flame to melt raw materials and then crystallizing the molten droplets into cylinders. With a Mohs hardness scale of 9 (scale 1-10), the resulting sapphire glass is extremely scratch-resistant and exceptionally hard, ensuring excellent visibility at all times.
