Case Back: Transparent. Patek Philippe generally uses a transparent back, and the screw-in design ensures tight waterproof performance. The transparent back cover has good waterproof performance and durability.
Crystal: Sapphire Crystal. The sapphire crystal is made of high-quality glass, and the dial is clearly visible. Tips: The A watch is applied with mineral glass instead of sapphire.
Hand: Rose Gold-tone. As you can see in the pictures above, the hand design of the watch is rose gold-tone that is simple but luxury.
Second Markers: Minute Markers around the outer rim. The design of other marks in the watch is also called the hand of the clock. This design element is used in many famous designs, such as clocks and other objects.
Dial Markers: Dot. We can use an dotted watch to tell us what time it is, which is different from a normal dial.
