Citizen The Citizen Caliber 0100 Mother-of-Pearl (Super Titanium)

This was the mother-of-pearl edition of Citizen's Caliber 0100, limited to 200 pieces worldwide and now sold out. The 0100 is Citizen's showpiece, a light-powered quartz movement rated to within one second a year, and here the natural pattern of the mother-of-pearl dial is meant as a counterpoint to that precision, the seconds hand marking time against something that took years to form. The case and bracelet are Super Titanium hardened with Citizen's Duratect Alpha, 37.5 mm across, with a sapphire crystal and 50 m of water resistance, and the watch weighs 65 g. Every part that touches the skin is non-steel, so the guide marks it nickel-free. It listed at $7,400 and is now a watch to find used.
