nice, It Is made of gum and It works. the description was correct. have to Say that I received the Watch 3 months After the order, It arrived later than expected, the Sellers has Always been correct and answered me. we were cooperating for refund but then I received It so I did not ask for It anymore. as I told to the seller probabily the fault Is to ali express system that declares a shorter time to receive the goods when It Is impossible to have Them in time, and not the seller's fault (I think).
