Casio Edifice ERA-100 Watches

Whatever one may say, but the Edifice ERA-100 watch got as many as three digital displays, which makes it not so ana-digi as a digi-ana. Together with other analog dial details, this creates a perfect symbiosis of functionality and attractive appearance. The older “brother” ERA200 certainly became an ideological inspirer, but here everything was done without a double sensor, and therefore cheaper.
