GF-8235D-1BCR / GF-8235D-1B

Sold Out

The base model (GF-8250) of the Frogman GF-8235D-1B is inspired by the exterior design of the second-generation Frogman DW-8200 from 1995. Like all Frogman models it has a screw-back stainless steel case and is an ISO Diver’s 200M watch. Unlike the early Frogman watches this one has Tough Solar power and a tide and moon graph. Zona Casio reports that this model has a DLC coating on the bezel and the rest of the case may be coated as well (no official confirmation on this yet but it does appear that the bezel has a DLC coating).
