Case Back: Transparent. In the world of watches, a transparent back cover is very common, not soft or flexible. It helps you see the engine inside clearly.
Crystal: Sapphire Crystal. Sapphire crystal is a good choice because it is a special anti-reflective coating that can minimize light reflection and provide scratch resistance without affecting its brightness. Sapphire crystal is a highly transparent crystal that can be used to make optical lenses, diffractive optical elements, and filters. Tips: The A watch is applied with mineral glass instead of sapphire.
Hand: Silver-tone. As you can see in the pictures above, the hand design of the watch is silver-tone, which is delicated and cool.
Second Markers: Minute Markers around the outer rim. The second mark on the dial is also called the clock hand. This design element has been used in many famous designs such as watches, clocks and other objects.
Dial Markers: Dot. The dot on the dial is used as a marker instead of Roman numerals and can affect the appearance of the dial.
