The cloisonné watch dials are in fine silver (999/1000) and the cloisonné wires are in 24k gold or fine silver wire. They have been fired in a kiln at 800°C at least 15 or more times. Each watch has an official French jeweler’s mark. I collaborate with the watch company Celeste Watch Company based in the United States. They install my enameled watch dial into their watch. The watches feature a Swiss quartz movement with a sapphire crystal and are water resistant up to 30 meters. The watch bands are made of leather.
