Crystal: Sapphire Crystal. Sapphire glass is a natural material that can reflect light to create optical illusions. Its long-lasting anti-reflective coating makes it ideal for scratch resistance, and the brightness of the crystal remains almost unchanged.
Second Markers: Minute Markers around the outer rim. The minute mark on the outer edge of the glass is a design element that represents time. It is also called the hand of a clock. This design element is used in many famous designs, such as clocks and other objects.
Bezel Material: Stainless Steel. A luxury watch with a stainless steel bezel is one of the most beautiful and delicate parts in the watch. The stainless steel bezel provides a durable, endurable and expensive look to the watch.
