A departure from its predecessor, which featured a full black exterior, the GMW-B5000TVB is eye-catching with its three-color switching pattern of brown, silver, and black. To realize this design, Casio made full use of multi-colored IP processing. The base titanium case is treated with titanium carbide (TIC) to ensure scratch resistance, and then masked to create a silver zone in the center of the case. After applying brown IP to the entire case in this state, the lower left corner of the case is masked to preserve the brown IP, and then black IP is applied to the entire case. Finally, when the center and bottom left of the case are unmasked, a beautifully color-coded pattern is revealed.
This may seem like a simple process, but in fact, this masking process is very special. The reason is that ordinary masking would have resulted in twisted or chipped color boundaries, and to avoid such defects, the color boundaries had been placed so that they overlapped the concave portions of the watch. With the new manufacturing method, however, this is no longer necessary, and the borders can now be expressed firmly even on flat surfaces.
