The GW-8230B is a faithful reproduction of the original in form, color, and even size. Compared to the recent MASTER OF G models, it is surprising to see how much smaller the early Frogman models were. One of these was the inclusion of Tough Solar. Unlike in the past, the power generation efficiency of solar panels has improved, but it still took a great deal of trial and error to create the look of the original model while securing the light-receiving area.
In addition, the sub-display, which in the original displayed diving time and calendar, has been changed to a tide graph and moon data in this GW-8230B. In its long history, Frogman has always made products that reflect the requests of divers, and all of its recent models have been equipped with a tide graph, but since "evolution" is also an important theme for the GW-8230B, these functions were deemed essential. However, it was extremely difficult to incorporate the tide graph and moon data into a small display while maintaining the original aesthetic - in other words, ensuring legibility - and this too was achieved through repeated trial and error.
