they are not wind up,i have 3 one for sure is antique the other 2 i am not particularly sure. The antique one is black and silver and the band stretches and there are silver gems around the face and black ones beginning in the band. there is no brand name on it it only says quartz. the battery size is the small ones. The 2nd watch is silver linked band with a pink face and the brand is Anne Klein the second. The 3rd is silver with big links and circles and there is no name on it the face is plain black and white. i believe all 3 take the same size battery. thats the best description i can give at the moment should have a picture posted asap
