The AW582 models that you have mentioned are GENUINE goods, the difference being the suffix, which denotes different colour variations.
Meanwhile, 行貨 and 水貨 don't make much difference when you buy at dealers like Time House and/or 邦士珠寶. The warranty treatment is the same: you buy the timepiece, keep the receipt for one year for warranty repairs, and don't temper with the watch (even battery change). You don't know which supplier in HK these shops get the Casios, you'll just have to trust them. In case of warranty issues, bring the watch back to the store of purchase, and let them take care of the rest. Don't bother asking these shops for the official warranty card -- under NO circumstances can you take control of any warranty documents.
Of course, the treatment at some retail locations are different. Javys, for example, issues their warranty cards to all Casio customers, but getting Casio timepieces at Javys' official locations often involves paying a premium price. City Chain also sources their Casios through Javys, and sell them at standard price, which scares off some buyers. However, City Chain issues Javys original warranty documents, which gives the customer more peace of mind regarding warranty issues.
Usually, the real Casio Japanese 水貨 involved are certain special edition models, as well as 電波時計 (especially, 5-band reception models and earlier ones), and usually can be found at stores in Sino Centre. These timepieces come with Japanese manuals only, and in case of warranty issues, the models concerned are very likely to be sent back to Japan for repair (although they can actually be serviced at Javys for a nominal fee).
