The Seaman has the typical asymmetric Frogman design, with the fake screws on the right side of the bezel (only the DW-6300 had fake pins instead of screws). These screws are pretty typical shaped on this Seaman. It somehow reminds me to a four leaf clover. Most remarkable for me on this Frogman are the straps. Instead of smooth resin, there is a structure in the middle part of the straps, which make them in my opinion actually look pretty sharp. The long strap has the usual shark fin shape as you find on all Frogman models, except the DW-6300. Compared to other Frogman models, the DW-9950 (and of course the DW-9900) fits rather small on your wrist. It is even smaller than the basic DW-6900 model.
Sorry, couldn't resist to do a little photoshop...

The Seaman wears smaller than a Basic 6900. I shot some pics during a break in the brewery and this GW-6900 is my brewing watch. I think they give a good comparison how it wears on my 7" wrist.
