In Japan the Frogman is one of the most loved G-Shock types amongst collectors.

The first G-Shock of the Frogman design was the DW-6300, released in 1993. It didn't had the name on the case, but it was soon nicknamed Frogman.

It was followed up in 1995 by the DW-8200 Frogman in the "Masters of G" series.

The next generation Frogman was the DW-9900 was introduced in 1999. It has the "Frogman" text on the right. The  Seaman (DW-9950) is the slightly different overseas version of this Frogman model.

In 2001 the Tough Solar GW-200 was released (not all models are solar).

It took until 2009 before Casio released a new Atomic Frogman version, the GWF-1000. It's a quite expensive model, but I have one, the Men In Burning Red GWF-1000RD-4JF.

In 2010 Casio came with a non-Atomic variant, the GF-8250-9JF, which was a tribute to the DW-8250Y-9T.
