Ok so I ordered a black gw6900-1v. I am now kinda wanting to have a white one as well. So my options are to buy a new bezel and band that I can interchange or buy a white watch. Would it be practical to change the bezel and band whenever I wanted to wear a white watch? This would save me a little bit of money. Or would it be worth the extra money to buy a whole other watch? I found a white dw6900 for under $100. Is there any dif between the gw6900 and dw6900? they are both atomic solar watches correct?
