The Watch Spotter 
The Official U.S. Navy SEALs Website offers many public domain promotional photos, some featuring Navy SEALs wearing the Casio G-Shock DW-6600 watch during training. It’s common knowledge that the DW-6600 was issued to Navy SEALs in recent times and these photos are evidence of that. The DW-6600 is also featured in the 2014 film American Sniper starring Bradley Cooper, based on the life of Navy SEAL Chris Kyle who wrote about wearing a G-Shock in his memoir.
The DW-6600 is considered to be one of the all-time classic G-Shock gold watches and was a very popular military watch. It first appeared in 1994 and was one of the longest running models. It was a preferred watch for military use due to its low cost, light weight, shock protection, reliable 200-meter water resistance, 24 hour mode, and electro-luminescent backlight with afterglow (staying illuminated for a few seconds after the button is pressed). The DW-6600 is also known as the first G-Shock to feature the “EL” backlight which illuminates the entire display.
The DW-6600 effectively replaced the Rolex Submariner as the standard SEAL watch. The model was discontinued by Casio in 2010 with remaining stocks lasting into 2011. Since then Navy SEALs have been known to wear G-Shock and other brands like Suunto and Casio Pathfinder (now known as Pro Trek). Today there no longer appears to be a specific model that is recognized as the standard SEAL watch, and the type of watch a SEAL wears in the field is often a matter of personal choice.
Current low-cost G-Shock watches similar to the DW-6600 with a front-facing EL backlight button include the G-Shock DW-6900 and G-Shock DW-9052. The DW-6900 is a popular military choice and as the model number suggests it is the closest in design to the DW-6600 with the same exterior shape. The DW-9052 is known as a military-issue watch in certain countries and in some special force units around the world.
