This is one of the materials used for watch dials. The shell of the black-lipped pearl oyster, a bivalve of the Pteriidae family distributed in the tropical western Pacific, is disc-shaped and flat, with a yellowish-brown exterior, but the interior is black-silver and has a strong, pearl-like luster. Therefore, it has been used as a material for craft products since ancient times. In high-end watches, it is thinly sliced and applied to the dial, with reinforcement for strength. Recently, due to its high light transmittance, it is also used as a dial for Eco-Drive watches. ☆ The luxurious, sparkling black mother-of-pearl, a dial that looks like a pearl, is very beautiful. It has various appearances depending on the viewing angle, and you can't help but stare at it. It's a watch like a piece of jewelry! In my subjective opinion, I find natural dials more captivating than the artificial dials made by the craftsmen of Grand Seiko.
