Case Back: Solid. The sturdy back cover is the “second skin” of the watch. It covers metal and provides daily wear protection for the watch.
Crystal: Sapphire Crystal. Sapphire glass has good ornamental properties and can bring people a brand new visual effect when looking at the time. Tips: The A watch is applied with mineral glass instead of sapphire.
Hand: Silver-tone. The style of the watch’s hands is silver-tone, that makes your watch luxury and funny.
Second Markers: Minute Markers around the outer rim. The design of other signs in the watch is also called the hand of the clock. This design element is used in many well-known designs.
Dial Markers: Dot. With a dot unlike the ordinary dial, the watch uses some simple dots as dial markings to show us what time it is.
