Case Back: Transparent. In the world of watches, a transparent back cover is very common and even the most common part of a watch. It is simple, durable and easy to see engine inside.
Crystal: Sapphire Crystal. We use sapphire crystal for the watch, which is a special anti-reflective coating that minimizes light reflection and provides scratch resistance without affecting its brightness. Tips: The A watch is applied with mineral glass instead of sapphire.
Hand: Silver-tone. For the watch, we apply with hands of silver-tone, which can highly improve the outlook of the watch.
Dial Markers: Dot. The luxury dot of the watch dial markers is used as a marker instead of Roman numerals and can affect the appearance of the dial.
