So I have been wanting a way to carry 2 watches with me when traveling. It is hard to find cases for traveling that fit larger watches. Usually they only fit small classic size watches. The bigger G-Shocks won't fit these small cases. I found this great case made by Oakley specifically made for large watches. It's called the Large Watch Vault. It's made very nicely and seems very sturdy and protective. It's like a nice sunglasses case, it won't get crushed or scratched easily. Just put you watch in it and throw it in a bag.
Just wanted to share this. It fits my Frogman and Gulfmaster like a glove. Oakley also makes a smaller version that would be perfect for a 5600 type square. I might have to get one of those for my GW-5000.
