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. Sapphire crystal is the best choice for most people. Sapphire’s impact resistance, air tightness and hardness are higher than other materials, and the processing cost is higher, so it is mostly used for top watch brands. Tips: The A Replica 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 can highly improve the outlook of the watch.
Second Markers: Minute Markers around the outer rim. The second mark on the watch is located on the outside of the clock and is used to indicate the time.
Dial Markers: Roman Numeral. The watch with Roman numeral is used as a marker instead of dots and can affect the appearance of the dial.
