And in the program meshup, I got a nice 3-D model watch. Then clean the no use staff, use the method showing in the video by using 'select face by vertex color', select the grey color and delete all the surround watch staff.
And now select 'surface reconstruction poission', and change the octree depth to 10. And get the final model but without color. You could see the shape of watch and with some support ground
Now transfer the orginal color to the plaster. And save the project to .obj. And use the 3D Max to open this floder.
