Hi guys, I was looking at Justin/Mike's 320 for sale: http://omegaforums.net/threads/omega-320-chronograph-18k-gold-recent-service.5613/ compared with Ash's http://omegaforums.net/attachments/dsc_8476-omegaforums-1010-jpg.18940/ and noticed some differences with the dials, including the lack of the tachy on Justin's, and the slight pillow/cushion effect on Ash's, creating the shimmering effect. Are there any other dial combinations in these? Daniel
