i took this shot yesterday. I was enroute to a meeting, and I noticed that the light was playing off the dial. I have not really been able to show the guilloche on th S dial well before. Normally you look at the watch and it is black. The guilloche is not apparent. There was also one moment when the sun turned the color of the dial to silver grey. I could not capture that effect. I will have to try a real light set up to control that
