Thanks Mike, now I know why these watches are not popular here, it seems that many have the perception base on the first generation, the AA or AB series. I personally don't fancy these first gen either and i only have one the GB-5600AA-1a which reminiscent the first ever G the DW-5600C ,first gen are slow to connect and disconnect,lack many control functions and only have CDT up to minute interval. Now for the gen 2,it's a total different beast,it's much faster and shows caller names and number.while I understand that many may not have the right phone and few years down the road these watches may no longer works is a concern, i do feel that even without Bluetooth, they are still great G shocks, take the GB-X6900B-1 now, priced at Amazon for around 120 plus, as compare to normal GD-X which cost around 80 to 90 plus for the ordinary series, i do feel the extra alarm, the vibration, the 100 cities world time, the 1 second CDT,the great viewing angle without shadow distortion and bigger digits , are well worth the extra money over the normal GD-X, as for looks and colors, they are compatible with any GD-X band and bezels if you ever get bored of the looks. Now back to the right phone topic, i guess at this point because i have the right phone and the right app,these watches serves its purpose well for me, at least for the next 2 to 3 years to come, then it's just like buying any other smart watches from Samsung or LG or Moto etc,few years later, these smart watches will also be obsolete because they no longer have the processing power to keep up with new phones. Then they will definitely be useless. Not so for the GB-B series, well, at least they are still G shocks which doesn't need a phone to serve its basic purpose, as a G-Shock ,of course it's just my point of view,and I totally respect everyone's decision on their preference of G-Shock. The Bluetooth strength is also the weakness of the watch when it comes to consumers' expectation. It's just such a pity.
