I have a Motorola citrus phone but It is no longer of any use as by mistake I dropped it and its screen get damaged. So I can’t use that phone anymore and I want to buy anew phone. One of my friend told me that I should go for wrist watch phone. I have never heard about this type of phone. Is this a combined version of wrist watch and phone or it is just a phone at wrist. Try to elaborate the features of common wrist watch phone?
