Case Back: Transparent. Patek Philippe usually uses a transparent back, which is not soft or flexible at all. It helps you see the engine inside clearly.
Crystal: Sapphire Crystal. Sapphire glass has good thermal properties, excellent electrical and dielectric properties, and is resistant to chemical corrosion. It has the characteristics of high temperature resistance, good thermal conductivity, high hardness, infrared penetration, and good chemical stability. Tips: The A Replica is applied with mineral glass instead of sapphire.
Hand: Silver-tone. The hand design of the watch is silver-tone, which is the same color as your case color. It fits the watch well.
Second Markers: Minute Markers around the outer rim. The minute mark on the outer circle is a design element that represents time, and the second mark is a small disc placed on the outside of the watch to indicate the time.
Dial Markers: Roman Numeral. According to a study, the human eye is sensitive to number, unlike the ordinary dial, the watch uses some clear numbers as dial markings to show us what time it is.
