When I received it, it was fine and working correctly. I took it off and placed it on my bedside table in my bedroom and when I went to wear it again, it didn't work. I have followed the instructions book both times when I wound and set the time but the thing I'm noticing this time is that the internal parts (in the centre bottom viewing circle) that were moving when I first received, set and wound it, are no longer moving.

(I selected bicolour because the watch face is gold and blue..?)
