This is a series in which three editorial staff members from the Japanese edition of Chronos give their impressions of popular models and discuss them. This time, Editor-in-Chief Masamasa Hirota, Deputy Editor-in-Chief Yukiya Suzuki, and newcomer Yasunori Doi will freely review the Oceanus OCW-T4000C-3AJF.

A unique dial color that combines blue and green
This multi-function connected watch features world time, home city swapping, a full auto-calendar, and mobile linking via Bluetooth®. It features a blue-green dial colored from both sides of the baseplate. Tough Solar. Approximately 20 months on a full charge (in power save mode). Ti (diameter 42.8mm, thickness 11.9mm). Water resistant to 10 bar. Price: 115,500 yen (tax included).
(I.e.
Well, this time we have the Oceanus "OCW-T4000C-3AJF." Following on from the previous "OCW-T200S-3AJF," this also has a green dial, which is an intricate color scheme.

The polycarbonate dial is coated with blue and then printed with green on the back. The color is somewhere between green and blue, and it changes color quite a bit depending on the light.
(I.e.The structure allows the printed surface to be seen through the vapor-deposited surface, which I think is a typical Casio attempt.
Hirota
Since it's made of polycarbonate, does that mean the entire dial generates power?
(I.e.No, it seems to be only the inner dial.
HirotaSo, did they try to prevent the solar cell from clouding the color? It means they really wanted to improve the color. The intention to "make the color come out beautifully" is clear, and because the cell is not visible, there's no sadness about solar dials.
The dial, which makes full use of Casio's poly-molding technology, is a highlight
(I.e.But if it's in-dial power generation, why didn't they use metal for the base plate?
HirotaHmm, I think Casio probably doesn't yet have the technology to make metal dials.
(I.e.Ah, I see. On the contrary.
HirotaWhen Casio first entered the watch industry, they were a new manufacturer and couldn't use metal cases, so they made plastic watches like G-SHOCK. As a result, they have accumulated a lot of plastic molding technology.
(I.e.Since then, both G-SHOCK and Oceanus have grown to the point where they can use metal cases.
HirotaI previously went to Yamagata Casio to do some reporting and saw the plastic molding process, and it was amazing. I don't think there are many factories that do plastic molding that well.
DoiThe indices and inner dial frames of this model are also made of plastic.
HirotaThe indexes are also plastic? Amazing. They're comparable to metal, so much so that you wouldn't know it unless someone told you. Casio has really improved the precision of their plastic molding molds, and even if you look at the cheapest G-SHOCK, the molds are clearly better than before. The line that appears when the top and bottom of the mold are mated together is called a parting line, but it's become much less noticeable.
