Nice video I’ve been looking at this watch as I don’t have a porcelain dial ... hmmm ... Minor note: Seiko is waaaaay more integrated than Rolex. Rolex doesn’t make its own sapphire crystals or hands. Seiko does; heck Seiko even grows the crystals for their GS quarts movements 🤷🏾♂️
They are both great watch dials I like them both but they are different. While similarities are shared between the two materials, porcelain is a ceramic made by firing a clay substance while enamel is produced by fusing powdered glass to a substrate material. I don't think one is better than the other they're just different.
