I own only two G-Shocks at present, a DW-5600E and a GW-4000. As much as I like the DW-5600E, it's frustrating to not be able to make adjustments both up and down. For example, if I want to change the countdown timer from 50 minutes to 45 minutes, I only have the option of pressing the upper right button to add minutes. I can't use the lower right button to subtract minutes because it operates the light. On many G-Shocks, as you know, there is a dedicated light button in the center bottom. Do all of these G-Shocks allow for up and down adjustment, whereas any square G-Shock will not (e.g., the GW-5000)?
If I want the functionality of the DW-5600E plus up/down adjustability plus world time, what would you recommend or suggest? I'm considering the GD-350-8 but am open to other suggestions.
