Hey guys, after being inspired by a post on here on modifying the gshock to enable the use of a zulu strap, i went ahead and followed all the instructions and here is the result below.
Gshock mudman GW-9000A
What I needed to carry out this little project:
Buy a Suunto Vector strap (these straps come with 2 C-clips, these clips are why you are buying the strap). I live in the UK so ordered it from here

Also you will need a 22mm Zulu watch Strap. this strap will feed through the C-clips. I bought my one here, its got pvd buckles so its all black.

The last thing you need is a biro/pen. you need the tube inside that contains the ink, but use an empty one. This tube will have to be cut with a scissors into 4 pieces. each piece being very short so its fiddly. The screws that hold the strap that came with your gshock will feed through the C-clip, and then through the small piece of biro, then in to the gshock. dont screw. same thing goes for the other side. I found i had to cut the pieces several times to get the correct length. SO, when the first side is screwed in, you will nee to do the same for the other side, but it can be tricky, so i found the best way to get the byro tube into the right place was to just drop it in to the gap (you will know what im on about if you have completed the first bit) and then feed the screw through the C-clip then into the watch again. Be sure you have cut the byro tubes to good lengths , because if you cut them too short, the C-clip will bend when you screw the screws in all the way.
The Photo below shows part of the biro tube just after the Clip on the inside, watch is a bit dirty, but id worry if a Gshock was too clean.
The zulu strap felt stiff and uncomfortable when it was new, but after 2 days of wearing it in, it feels fine now.
