Patek Philippe Super Complicated Timepieces Series 5303 Modification (Engraving Series-St. Paul's Cathedral)
The decoration is inspired by London St. PaulSt. Paul's Cathedral。The master manual carving removes excess metal, giving this miniature painting a three-dimensional embossed feel. The depths of these carvings are 1 mm and 0.5 mm respectively. First, carving knives of different size are used to carefully carve the outline of the pattern, then a copper engraving needle is used to further carve out subtle details, and finally, they are polished, polished and sandblasted to create a contrast in texture. The entire manual carving process takes more than 120 hours.
