The DW-5600 has been the legendary - signature model of G-Shock for decades. Next to it is the other sibling - the DW-6900. The base model DW-5600 has been upgraded with the latest features and functions, which can be found in a series of new models. Another reason why many watch enthusiasts love the DW-5600 is because of easily available spares like the module (the movement), the hard case, and the BNB (bezel and band). As a watch collector, a DW-5600 is a must-have. I call my DW-5600 'the morning watch' . Semi-retired, my morning routine - is exercise, house cleaning, or gardening. My 5 cents WIS. Hoped you will love it.
