I recently purchased my first G, a DW-5600e and I love it. I am interested in what lead other people in their decision to buy a specific model G-Shock.

I liked the DW-5600e for it's smaller size and retro design. It has all the basic features I need, and shows the time in all the modes. For the money it couldn't be beat. I figured the EL backlight would be brighter than on the solar models, and more cost effective. Assuming that the battery costs as much as $5 and that I go through one battery a year, I could afford to change the battery 12 times before I start getting close to the price solar models I saw online. Being able to sync to atomic time was an attractive feature until I wondered whether I actually really NEEDED it. I can sync the watch to atomic time myself whenever I feel like it, and the quartz accuracy wouldn't be off by more than 30 seconds in a given month (at most).
So far it hasn't come off my wrist. I'm loving this watch and can't believe I never gave these watches a chance until now. Now let's hear why YOU chose your model (if you have lots, choose the one you wear the most).
