Yesterday I received the JaysandKays adapter kit for my G-9000-3V, which includes both the adapters and a nice-quality 22mm 3-ring Zulu strap (or a 2-piece strap if you prefer). I chose the strap in the olive color with the black PVD hardware. The kit is $25 on eBay.
The adapters fit very well on the G-9000, and they have a nice textured finish. They give the watch a more substantial look, and allow easy swapping of 22mm Zulu or NATO straps.
Here is the JaysandKays Zulu on the adapters.
I also tried this setup with a 22mm Barton NATO. This works very well, and the NATO flap doesn't make the watch ride up as it did with the standard adapters on my AE-2000. I have some other Barton NATOs that might look good with this watch.
I like how the white and red stripes on the strap match the lettering and markings on the dial.
A benefit of using a Zulu or NATO strap is that it gets those rough bumpers on the case back cover a little away from the wrist. Sometimes they would be scratchy on my wrist when I used the standard G-9000-3V strap.
I recommend the JaysandKays Mudman G-9000 adapter kit. It's good quality stuff at a reasonable price.
