Case Back: Transparent. The transparent back cover is not soft or inflexible in any respect. It helps you see the engine inside clearly.
Crystal: Sapphire Crystal. Sapphire crystal is a good choice, because it can block moisture and dust, protect the hands, dial and movement. Tips: The A Replica is applied with mineral glass instead of sapphire.
Hand: Rose Gold-tone. The design of the watch’s hands is rose gold-tone, which fits your watch’s dial well.
Second Markers: Minute Markers around the outer rim. The design of the second hand in the watch is as shown in the figure above. It is called the hand of a clock. This design element is used in many well-known designs, such as clocks, clocks and so on.
Dial Markers: Roman Numeral. Roman numeral dial markings are different from ordinary dials. The watch uses a few simple arabic numbers to mark the dial to indicate the current time.
