Casio is extending its Oceanus line of solar-powered radio-controlled watches with models featuring deep blue ceramic bezels made using traditional Japanese Edo Kiriko cut glass techniques.
Edo Kiriko is a traditional Japanese technique of cutting patterns into glass that dates back 180 years. Edo is also the original name of the city now called Tokyo.
The Oceanus OCW-S4000S and OCW-S4000C blend traditional Japanese craftsmanship and advanced technology, inspired by contemporary Tokyo, a city of urban sophistication, history and tradition.
The watches are equipped with the Casio Connected Engine module that links to a smartphone to ensure it tells the correct time in any timezone.
