Case Back: Transparent. The hard transparent back cover is a great way to add style and elegance to your wrist. High-end clear back watches are becoming more and more popular.
Crystal: Sapphire Crystal. As a good watch, we use sapphire which has higher impact resistance, airtightness and hardness than other materials, and the processing cost is also high, so most of it is used for top watch brands. Tips: The A watch is applied with mineral glass instead of sapphire.
Hand: Silver-tone. For the watch, the hands is silver-tone, which can highly improve the outlook of the watch.
Second Markers: Minute Markers around the outer rim. The second mark of the dial design is a small disc, placed on the outside of the clock to indicate the time.
Dial Markers: Dot. We can use watches with dots. Unlike ordinary dials, watches use some simple dots as dial markers to show us the current time.
